Used SEMITOOL 470S #103617 for sale

SEMITOOL 470S is an advanced photoresist system for semiconductor processing. It is used in the fabrication of integrated circuit (IC) boards and other electronic devices. The system utilizes a thermo-optic technique to coat photoresist onto the wafer in order to program the chip layout and features. The process begins with a wafer assembly stage, followed by photolithography exposure and spin-coating. During exposure, a mask is placed between the wafer and the photoresist, then light is passed over the model. The resist is selectively exposed in areas where the light shines, while unexposed resist is removed in areas where the light is blocked. The photolithography exposure is then followed by a coating step, where the wafer is placed in SEMITOOL 470 S' thermal-optics coating chamber. This chamber allows for precise control of the thermal profile, temperature, and uniformity, enabling consistent, repeatable photoresist deposition. The chamber has a multi-zone heating mechanism, with one or multiple fan-assisted options for enhanced stability. Finally, the photoresist is cured in the curing oven of 470S. This oven has advanced precision control to ensure that the photoresist is properly cured and hardened. In addition, the oven can be programmed for multiple recipes, with pre-set temperatures and dwell times. Overall, 470 S is an advanced photoresist system for producing tight line widths and high pattern resolution. Its precision, repeatability, and thermal control enable reliable fabrication of IC boards and other sophisticated electronic devices.
