Used Unknown BPE-2000W #9282437 for sale

SteamUnknown Unknown BPE-2000W is a photoresist equipment designed for microelectronics and semiconductor industry applications. This highly versatile system can be used for etching, patterning, modification, and repair of photoresist structures on a wide range of substrates. This unit utilizes a novel electrochemical process called Property-Aid, which promotes selectivity in the etching process by utilizing a high voltage differential produced by two photoresist layers of films sitting at different potentials. This enables the etching of close geometries without the need of a mask, while creating a uniform structure and maintaining the substrate integrity. The process begins with the spin-coating of a photoresist film on the required substrate. BPE-2000W machine utilizes blue-light to irradiate and activate the photoresist to allow selective etching, minimal bridging, higher annealing temperatures, and improved edge variation control. During the irradiation process, an optical densimeter is used to ensure uniformity of the exposure layer, and the recipe developed selects the optimal irradiation parameters based on the substrate composition, etch depth, and assumed photoresist film adhesion. Once the irradiation is complete, the two photoresist layers of films are connected to two electrodes, the lower one connected to ground and the upper one connected to a high voltage. The Property-Aid process initiates with a controlled current provided by Unknown BPE-2000W tool to etch a pattern into the photoresist film. The property-aid process also compensates for the higher temperature of the substrate during the etching cycle. Once the pattern is etched, the post-processing stage can consists of various processes, including dicing, flip chipping, reverse-etching, and via formation, depending on the application. BPE-2000W asset has a built-in dust protection feature to prevent particles from entering the photoresist film during the post-processing stage. Unknown BPE-2000W model can also offer optimal etch steps, minimizing the need for manual adjustments and enhancing uniformity and throughput in the microfabrication process. In conclusion, BPE-2000W equipment is a versatile and reliable photoresist system for the microelectronics and semiconductor industry, designed to etch close geometries, maintain substrate integrity, and improve edge variation control. Through the use of the Property-Aid process, the photoresist structures can be etched without the need of a mask, and the post-processing can consist of a variety of processes for optimal results. This reliable unit is designed to maximize uniformity and throughput, while ensuring dust protection and easy manual adjustments.
