Used SEMITOOL WSST #9097196 for sale

SEMITOOL WSST is an advanced photoresist equipment that utilizes ultra-violet laser technology to create patterns on semiconductor materials. The system is designed to deliver repeatable, long-term results with reliable uniformity and accuracy. The unit consists of two main components - the laser source and the stage. The UV laser source equipped with an acousto-optic modulator (AOM) to control the laser power. This provides precise control over the patterning area, allowing for high resolution feature definition. Additionally, the controller has a number of adjustable parameters which allow the operator to adjust the intensity, frequency, and pulse duration. The stage is the centerpiece of the machine; it is composed of three separate components - the substrate holder, the liquid crystal monitor, and the exposure mapping tool. The substrate holder supports substrates of up to 6-inch diameter, allowing for multiple resist patterning of substrates in a single batch. The liquid crystal monitor allows for precise positioning of the substrate, enabling the operator to accurately align the laser beam with the patterning area. The exposure mapping asset measures the exposure map during the patterning process so the operator can ensure the desired patterns are properly exposed. The model also includes a web-based GUI for easy operation. The interface allows the user to configure settings such as the laser power, the number of pulses, and the exposure time. In addition, the GUI also provides real-time feedback about the current status of the equipment, including patterning progress and the temperature of the substrate. In summary, WSST is a high-precision photoresist system that enables reliable patterning of a variety of semiconductor materials. The unit features an intuitive web-based GUI and advanced laser technology for precise control over the patterning process.
