Used GCA 8000/8500 #9101642 for sale

GCA 8000/8500 is a wafer stepper manufactured by GCA Corporation. The equipment is composed of a four-axis wafer-handling robot, a precision microscope, a motorized wafer stage, a high-resolution, cooled CCD camera and an integrated control system. GCA 8000/8500 has a versatile modular design that allows for easy upgrades and interface flexibility. The four-axis wafer-handling robot is responsible for loading and unloading of wafers to and from the machine. The robot is capable of handling up to 200mm (8 inch) wafers and also features an auto-alignment capability. The precision microscope allows for precise alignment of the wafer to provide focus and magnification controls to allow for imaging of patterns as small as 0.5 μm. The motorized stage is capable of accurately positioning wafers to ensure accurate imaging and overlay registration. The CCD camera is the heart of the unit and is capable of providing true geometrical and resolution specifications of 0.35 μm for the highest quality imaging. The camera also has a choice of color filters that are suitable for 3, 5 and 6 inch wafers. The cooled CCD allows for low noise images at high speeds for optimal throughput. The machine's intuitive control tool with touch screen interface is user friendly and simple to operate. An integrated search-and-find feature allows for easy retrieval of stored patterns and GCA 8000/8500 provides full capability for high speed manual, semi-automatic or fully automated exposures. GCA 8000/8500 is well suited for applications in the semiconductor industry such as mask alignment processing, optical mask inspection, tape automated bonding, MEMS device fabrication, IC packaging and PCB processing. The asset offers unparalleled performance, reliability and flexibility necessary for precision wafer processing.
