Used SEMITOOL SST-742-280 #293657532 for sale

SEMITOOL SST-742-280 is a photoresist processing equipment designed for high precision photolithography. This system has the ability to handle wafers up to 8" with a process capability from 5um to 4um resolution. It is designed for ultra-precise imaging on the wafer surface which is essential for creating high-density integrated circuits. SST-742-280 unit is based on an inverted optical microscope machine for light exposure and precise positioning of the wafer. The wafer is exposed to ultraviolet light through a high-precision mask. The mask has a variety of fine grids that allow you to adjust the size and shape of the images. The wafer is then exposed using a high-intensity ultra-violet lamp. The intensity of the light can be adjusted to provide the desired photoresist image resolution. SEMITOOL SST-742-280 tool includes a liquid crystal display (LCD) monitor that allows the user to view the photo mask details in real time. The LCD monitor is also capable of displaying feedback images of the photoresist patterns for quality control. This asset also includes an automated alignment unit which ensures that the mask is accurately lined up with the wafer to achieve precise alignment. SST-742-280 is equipped with a conveyor model to transfer the wafers between processing stations. This equipment includes peel-off capability to allow for more efficient processing of individual wafers. It is also equipped with a recessed table design to provide improved contact between the wafer and mask. SEMITOOL SST-742-280 system is a highly reliable and flexible tool for precise photolithography. It supports post-exposure, etching, and post-bake process to finish the job. This unit is built with a programmable logic controller and a self-optimizing monitor to ensure that the process settings remain constant throughout the job. Additionally, this machine includes a temperature-controlled environment which helps to ensure reproducibility of the photoresist images.
