Used TEGAL 903E #293806912 for sale

TEGAL 903E is a highly precise etcher/asher ideal for applications such as plating, masking, and semiconductor device manufacturing. It is part of TEGAL family of etchers and is capable of processing wafers in sizes up to 8 inches in diameter. It features an innovative automated PVR (Precise Vacuum Regulating) system, which eliminates manual control of the process pressure by ensuring uniform vacuum throughout the entire cycle. This improved vacuum control helps to maintain precise etching parameters and ensures optimal results. In addition, TEGAL 903 E is equipped with a custom designed two-headed electric heating element that is designed to distribute heat evenly across the wafer. The etcher also has a robust, yet user-friendly control system. It is programmed to keep the wafer temperature within a precise range based on the etching process parameters. A built-in countdown timer ensures a reliable etching process. Furthermore, 903E utilizes a specialized Windows-based software program to control the machine. This allows for customizable parameters and makes it easier to keep track of the etching process. The etcher is also equipped with a sophisticated digital chiller that allows for temperature regulation. This enhances the accuracy of the etching process, by ensuring that the wafer does not overheat during the process. In addition, 903 E features a built-in, run-time recorder, making it easier to track the results of each etch process. TEGAL 903E has a maximum etching rate of equal to or greater than 20 microns per minute, making it ideal for precision etching of delicate materials. It is also able to etch through high-density polyimide, polyester, and quartz substrates. This makes it suitable for use in high-tech industries such as semiconductor device manufacturing and precision machining. The etcher is designed and manufactured to the highest standards of quality. All its components are made of corrosion resistant stainless steel and are designed to provide years of reliable, efficient operation. TEGAL 903 E is rigorously tested and inspected before it leaves the factory and comes with a one year warranty. As such, it provides a reliable and cost-effective way to etch both large and small wafers.
