Manufacturer:Tegal
Condition:Never Used
Tegal 900 series (tegal 901e,Tegal 903e) Plasma/RIE etch System are used by the Semiconductor Industry for integrated circuit fabrication. The system are used in one part of the sequence of manufacturing steps that transfer a pattern formed from a layer of photosensitive material, the photoresist, to a layer that makes up a permanent part of the final device. The process of defining a pattern with photoresist known as photolithography, while the etch process transfers the photoresist pattern to the permanent layer.The 900 Series systems deliver highly reliable, repeatable results in etching a variety of films used to manufacture semiconductor, telecommunications and optoelectronics devices, flat panel displays and thin film magnetic heads.
The Tegal 903e is a versatile diode plasma etch tool designed around a production-proven transport system that can accommodate 75-150 mm round silicon and gallium arsenide (GaAs) substrates. The transport can also be configured to accommodate rectangular substrates from 100-125 mm on a side.
