Used SVG / PERKIN ELMER / ASML 642 HT #293645522 for sale

SVG / PERKIN ELMER / ASML 642 HT is a mask aligner, or optical lithography tool, used for measuring and aligning micron and sub-micron scale features. It is the latest version of the reliable and popular SVG 641 HT, and is optimized for processing wafer sizes up to 200 mm. SVG 642 HT makes use of an excimer laser, LasertecTM programmable stepper and a unique alignment equipment with integrated low-temperature liquid-crystal photomask. The laser emits a high-resolution, uniform laser beam which is focused onto the alignment area of the mask. The programmable stepper precisely positions the wafer in a series of x and y directions, allowing for better alignment of the patterns on the mask relative to the wafer. In addition to its sophisticated alignment system, ASML 642 HT also features a number of other state-of-the-art technologies, such as its low-temperature liquid-crystal photomask for enhanced accuracy and resolution. This allows for larger feature sizes than with a regular optical photomask, enabling the formation of complex structures, such as self-aligned contact holes. 642 HT also features a unique, variable power optic unit which allows the user to fine-tune the power of the laser during the lithography process. This machine provides increased flexibility, allowing it to achieve the desired optical characteristics. In addition, PERKIN ELMER 642 HT also features a multipurpose, modular design which makes it a highly versatile tool for a variety of lithography applications. From basic photolithography for masking to more complex processes such as pre-bonds and hybrid constructions, SVG / PERKIN ELMER / ASML 642 HT provides a comprehensive solution for every user. SVG 642 HT is equipped with a fast processing speed of up to 6000 wph and a large area capability of up to 200 mm diameter. This makes it an ideal choice for high-volume production needs. Its robust design, reliable performance and affordability make it an ideal choice for users in need of precise and precise results in a wide range of production applications.
