Used VISION PRECISION GA 16 #9262207 for sale

VISION PRECISION GA 16 is a mask aligner designed for the production of wafer-level devices such as integrated circuits, memory chips, imaging sensors, and many other miniaturized technologies. The equipment uses photolithography to replicate patterns from a photoresist-coated silicon wafer onto a silicon master-mask, or "aligner". It employs two powerful, red-light laser beams that come from a fiber-coupled laser source, and pass through flexible opto-mechanical components for precise patterning and uniform control of the exposure on the masking layer. The laser light can be adjusted to different wavelengths, allowing higher resolution and higher throughput rates. GA 16 offers extraordinary accuracy and repeatability in its alignment process, with an alignment precision of approximately 25nm. This precision is ten times better than the traditional photolithography method, and enables creation of more intricate micro-devices. The system also features an automatic wafer-positioning unit that uses an automated microscope and fiducial recognition to precisely align the wafer to the mask. It also includes an array of advanced optical elements that allow adjustment of the beam parameters to suit complex patterning needs. VISION PRECISION GA 16 also utilizes a variable-slope reticle carrier for fine-tuned accuracy. This carrier facilitates precise, step wise registration of the mask on the wafer. An array of multiple-stage optics fine-tune the lighting and pattern resolution, and a special filtering machine enables quick protection of the optics from contaminates. The exposure process involves high-accuracy photo-optic rotary shutters that provide further adjustment of exposure. GA 16 is an efficient, sophisticated, and reliable mask aligner that is capable of operating in an automated mode with minimal human interaction. Its features enable precise and cost-effective production of micro-devices, providing manufacturers with many convenient features that make pattern replication on micro-scale a simple and error-free task.
