Used SVG 88 #293770159 for sale

SVG 88 is a photoresist system developed by SVG (Silicon Valley Group). Photoresists are light-sensitive materials typically used in the production of semiconductor and related electronic devices. They are essential in forming transistors, diodes, resistors, and other components. 88 is a thermal processing system designed to enable the printing and structuring of high-precision photoresist patterns on wafers. Its combination of features facilitate the fabrication of complex and intricate structures such as microscopic lines and through-wafer contacts. SVG 88 comprises three main components: a light source, a thermal controller, and a wafer holder. The light source consists of an array of miniature lamps with an output power of 40 milliwatts per lamp. These lamps emit energy in a uniform spatial distribution, enabling very precise etching of photoresist patterns. Furthermore, their extremely short exposure time provides fast patterning with minimal thermal exposure. The thermal controller and wafer holder help maintain the wafer at a uniform temperature during etching. This is achieved by use of an embedded temperature sensing head, which can measure very small temperature variations with high accuracy. The head is connected to a temperature controller, which is capable of making rapid and precise adjustments to the heating of the wafer. Finally, the wafer holder incorporates multiple degrees of freedom that allow it to manipulate the temperature-sensitive wafer in three-dimensional space. This affords great precision when positioning the wafer vis-à-vis the light source. It also reduces potential sources of distortion, ensuring a precise and uniform resist pattern. The features of 88 have made it a staple in producing complex structures with photoresist. It provides a robust and reliable solution for highly-accurate etching with minimized thermal loading. Furthermore, its user-friendly interface allows for fast and efficient operation, render it the preferred system by both experienced microfabrication engineers and students alike.
