Power Supplies for Vacuum Thin-Film Depostion and Coating

Compiled by Terrence Thompson, Contributing Editor

This Vacuum Technology & Coating product showcase includes power supplies used in a wide variety of vacuum-based production deposition and coating applications.
 
 Deposition and coating systems require extremely dependable power supplies. Fortunately, a wide array exists to fit virtually any application. With increasingly demanding deposition and coating system requirements, and the ever present cost considerations for industrial and scientific applications, the expectations for power supplies increases.
 
 Power supplies provide outputs of DC or AC in a wide range of power levels. Power supplies can have primary outputs ranging from very low to hundreds of kilowatts with frequencies from DC to 13.56 MHz or beyond. Depending upon the application, voltage or current regulation may be more important. Current ratings also can range from low to very high. These are but a few considerations when selecting a power supply.
 
Options Abound
 
 
How crucial is size and are matching networks and cooling systems needed? What kind of output programming and control are needed and what specific computer or network digital interface needs must be met? There are many choices to meet the user needs.
 
 With DC supplies, there are steady and pulsed outputs. Typical DC power options include high-current, high-voltage and voltage-regulation. Pulsed DC supplies, for example, can improve surface uniformity in applications such as semiconductor wafer copper plating.
 
 For AC supplies, many factors must be considered. High-frequency power sources must deliver reliable power for continuous, demanding use in vacuum applications including vacuum processing such as PVD, RF sputtering, plasma etching or deposition and reactive ion etching.
 
Very Reliable Power Required
 
 
Analytical instrumentation power supply voltage requirements can range from just a few volts to several hundred thousand volts, often with multiple critical voltages in a particular instrument. Standard and custom high voltage power supplies are used in instruments for spectroscopy and many other analytical imaging and process applications. Voltage ripple (or lack thereof), stability over time, repeatability and accuracy are factors to consideration if reliable scientific data are the goal. For analytical instrumentation used in production process control, reliability is very important.

Thin-Film Deposition Rate Monitoring and Controller Product Showcase

Compiled by Terrence Thompson, Contributing Editor
This Vacuum Technology & Coating product showcase includes the thin-film deposition rate monitoring and controlling equipment used in a wide variety of production, R&D and other thin-film deposition applications. (Also, see the related Annual Power Supplies for Vacuum Thin-Film Deposition and Coating Product Showcase)
 
 Depositing thin films requires that you must know both the precise rate of deposition and how to alter or control same. Deposition monitors/controllers determine film thickness during the coating/deposition process itself by acquiring continuous rate and thickness data. Depending upon the item being coated, inprocess monitoring and control may be desirable. In other applications, checking the finished film is certainly sufficient.
 
Getting and Maintaining Control
 
 
There are several ways to monitor and control thin-film deposition parameters as well as ways to characterize the deposited films and coatings. Knowing exactly what materials are being deposited, the deposition rates, film thicknesses and uniformity can make a significant difference in process costs as well as suitability for the task at hand.
 
 Quartz crystal monitors are mass monitors. QCM deposition monitors only provide continuous rate and thickness data. There are differences in the frequency with which measurements are made which makes a difference. Monitors do not control deposition rates.
 
 Deposition controllers automatically control the deposition rate, typically by adjusting the deposition power as required to maintain the desired rate. Their main advantage of controllers is that they provide very accurate rate control that results in more-consistent coatings. Controllers provide mass programming which is typically described in terms of density, Z-ratio or tooling factor.
 
 Optical transmission monitoring works for transparent substrates (optical density) and are widely used with many variations on the theme. Sensors are specified by frequency range in wavelength (nm). Also, the number of inputs and type can be used to index the substrate and thickness of film while monitoring the wavelength and coating rate. Associated controller outputs can help model the transmission curve or signal the process to terminate each layer when desired thicknesses are achieved.
 
 With non-transparent substrate optical reflection sensors, the frequency (wavelength) range and sensor polarization is checked. Controllers monitor the index of substrate, index and thickness of film, monitoring wavelength and coating rate. Controller outputs can model a transmission curve and signal to terminate each layer.

Phase II-J Retrofitable Computer Control for Sputtering Systems
 
 AJA International’s LabView based Phase II-J is a field retrofitable computer control system for magnetron sputtering systems. This straightforward, user friendly control system utilizes a large, flat-screen laptop in a 19-inch rack drawer connected to a single 7-inch high × 19-inch wide rack mount hardware module. The back panel of the hardware module is populated with connectors to interface to all aspects of the sputtering system. The Phase II-J control system allows the user to operate in either the “manual mode” or the “automated processing mode”. In the “automated processing mode,” the user designs process “layers” which are then compiled and saved as a “process.” The
 
system allows 10 unique user entry points, which are accessible only by password, limiting access to a user’s layers and preventing unexpected corruption of a user’s saved processes. The standard Phase II-J control system will accommodate up to five DC power supplies, four RF power supplies, one 4-way DC switchbox, one 3-way RF switchbox, (4) process gases, closed loop automatic pressure control and substrate temperature control. Processes are aborted if plasma is not detected. Special “soak layers” can be easily incorporated into the process. Finally, data logging is standard with an adjustable refresh period. Process data can be downloaded to common spreadsheet programs.

Thin Film Deposition Controller for Maximum Throughput in OLED Applications
 
 
 INFICON’s CygnusThin Film Deposition Controller maximizes process capability and flexibility for OLED (Organic Light-Emitting Diode) applications in the production of flat panel displays. Cygnus Thin Film Deposition Controller is unique in its ability to precisely control the ratios of up to six materials independently, or in any combination, with a rate resolution of 0.01 Å per second. This accuracy, powered by ModeLock—the patented INFICON quartz crystal measurement technology, is critical to the low-density materials and low deposition rates associated with OLED processes. As substrates are cycled through the system, flexible deposition sequencing allows continuous rate control and saves valuable production time by eliminating the need to reheat source material with every substrate. Automatic Zratio determination, or Auto Z, increases the accuracy of thickness and rate control and eliminates the need for the user to estimate the acoustic impedance (Z) ratio. This is especially important for maintaining thickness and rate accuracy for materials where the Z-ratio is not known. Extensive logic I/O features provide comprehensive process control integration. Cygnus also offers up to three digital to analog outputs per source – source power, rate, and thickness. The user can identify the true thickness deposited on the substrate from multiple sources through the Cygnus thickness-summing feature. Applications software provides complete programming of one or multiple Cygnus Controllers from a PC, using RS232 or IEEE interface.

Thin Film Coating Instrumentation
 
Nor-Cal offers an extensive selection of commonly used quartz crystal feedthroughs, sensors and multi-channel monitors, cables, quartz crystals, accessories and replacement parts for use in semiconductor, optical and industrial thermal deposition processes. Custom feedthroughs are available with a variety of flanges in all sizes. Our coating instrumentation products support one of the more popular methods of thin film measurement and rate control the crystal monitor, which utilizes the piezoelectric properties of a quartz crystal. The electrical characteristics of the crystal, which is held in place by the sensor, change during deposition. Single sensors are generally used for short deposition runs, whereas, dual sensors allow for longer runs. Dual sensors require an airline to operate a pneumatic shutter which covers one crystal at a time. The sensor is either welded to the feedthrough or attached with connectors. Most sensors are available with cooling lines. The application determines the correct choice of sensor. The sensor determines compatible feedthroughs and cabling. The chamber determines the appropriate feedthrough and flange. For application temps up to 150°C, electrical connection between the sensor and feedthrough is accomplished with a vacuum coaxial cable. A bakeable, one piece sensor/feedthrough replaces the standard in-vac cable with a stainless steel high-temp coaxial line for high temperature applications up to 300°C. The feedthrough is the air-to-vacuum connection between the sensor and the oscillator. The feedthrough transfers the quartz crystal’s piezo-electric vibrations to the oscillator via a short coaxial cable. The oscillator conditions the signals and transfers them to the monitor via another coaxial cable. The monitor then measures, interprets and displays the thickness, rate and frequency of deposition. Nor-Cal’s thin film deposition monitors are available with up to six independent channels to read six single sensors or three dual sensors simultaneously. Each sensor requires its own cabling and oscillator. Contact our sales staff for help with your system configuration.

EIES-IV Guardian ™ Thin Film Controller
 
Sigma Instruments, a supplier of QCM-based thin film deposition monitors and controllers, now offers a thin film controller based on the principle of Electron Impact Emission Spectrometry. The EIES-IV Guardianwas developed in collaboration with the original inventor of EIES, Dr. Larry Lu, of C Lu Laboratories. In EIES, the materialbeing deposited is thermally excited, which creates photons in proportion to the amount of material present. A photodetector measures the light emitted, which translates into the deposition rate of the material. Multiple materials are controlled by monitoring each material's unique optical emission spectra. The Guardian integrates EIES with Sigma's field-proven thin film process control software and a Windows-based PC, to expand the capabilities of EIES for today's complex films. For users of older Sentinel® EIES systems, Sigma's EIES-IV Guardian is compatible with Sentinel® sensors, to ease the cost of upgrading. The Guardian can control deposition rates from 0.1 to 10,000 Å/s. It operates one or two sensors, up to 8 optical inputs and controls up to 6 deposition sources, enabling co-deposition of up to 6 materials.

The unit has four slots for I/O cards that can house either an input card (8 optically isolated inputs) or an output card (8 form-C SPDT relays). The sensor-head/source-control modules provide two channels each for crystal frequency measurement and two separate, isolated, analog 0 to 10 volt (plus and minus) outputs for source control. The 880 can house four such modules, supporting up to eight channels of sensor input and 8 analog outputs, and enabling averaging and co-deposition functions. Advanced measurement technique provides high accuracy at constant 100 ms measurement period. RS232/485 interface standard, industrial fields busses optional. Flash memory removable module option for transferring process recipes, and for back-up in case of failure. Thickness display is 0.000 to 999.9 kA and the rate display is 0.0 to 999 Å/s. Source outputs are ± 2.5, 5, 10 volts @ 10 mA with 4 user definable function keys.

This crystal oscillation controller provides high resolution to 0.005Å, a multi-layer calculation for excellent film thickness results, an improved life span, simultaneous four element deposition control, and a flexible deposition program with up to 30 phases. The half-rack, high-speed CRTM-6000 provides film thickness control, deposition rate control, power control before and after deposition, and multilayer deposition control for applications that require multi-layer thin film deposition with high resolution. This controller features high resolution of 0.04 Å, high speed sampling rate of 125 milliseconds, a long life oscillator, a processing program that permits continuous deposition of up to 99 layers and an RS-232C interface.
 

 

 

 
  MIESEC Non-contact Accurate, Cost-Effective Measurement of Metal Film Thickness
 
ULVAC Technologies, Inc.’s MESEC, a new metal film metrology instrument for copper seed and electroplated copper layers on 200- or 300-mm silicon wafers. Designed for use in PVD, CVD, plating, and CMP equipment applications, the MESEC unit directly evaluates device wafers using the non-contact, non-destructive eddy current detection method. Copper films with thickness in the range of 0.03 µm to 5 µm can be measured with the higher speed, better accuracy, and at significantly lower cost than other methods. ULVAC’s proprietary amplifier circuit design in the MESEC unit enhances the Eddy current signal to noise ratio resulting in improved measurement accuracy. Additionally, ULVAC uses a small sensor, which strikes a good balance between spatial resolution requirements and background noise elimination. ULVAC has developed two types of the MESEC units: Built-in Type (MESEC BIT) and Stand-alone Type (MESEC SAT). The MESEC BIT is designed for in-situ measurements in thin film deposition systems and surface preparation equipment. The MESEC SAT is a freestanding metrology instrument that measures any thin conductive metals or alloy films (Al, Cu, AlCu, etc.) on silicon wafers. This unit features an open cassette, SMIF or FOUP load port design and is used for in-line or off-line measurements.
