Used TAMARACK M304 #9398334 for sale

TAMARACK M304 is an advanced and reliable optical stepper designed specifically for the microchip industry. The stepper utilizes a high-precision placement equipment that ensures the highest precision and repeatable accuracy during the device completion process. Its multi-camera, five-axis motion system allows for fast throughput rates and facilitates the production of high-yield products. M304 features a 200mm wafer stage that can handle wafers up to 8 inches in size. The stepper also includes a custom Exposure Column for die attenuation control at every wafer site. This exposure column also enables high- fidelity broadband exposure that reduces the chance of exposure errors during the exposure process. Furthermore, the integrated microlens scanning unit helps to minimize pixel aberrations and ensures each die receives an accurate exposure. The machine's high-flexure level compensation mechanism can correct misalignments up to 1 micron, which helps to reduce wafer scrap. The machine also features a multi-axis scan stage with a 50 kHz scan speed that facilitates high-speed, dynamic scan at each wafer site. Additionally, the tool's multi-resolution imaging path enables ultra-high resolution imaging and enables image acquisition in less than 1 second. This stepper also offers advanced target recognition and focus development algorithms that have been designed to help reduce exposure time and focus errors. Moreover, the asset has a multi-zone dose control model that allows the user to adjust the dose levels at each wafer site. The stepper also includes extremely precise and repeatable vacuum and load/unload functions that are essential for image placement accuracy and throughput. TAMARACK M304 provides advanced functionality and extremely high precision, making it perfect for use in microchip applications. Its five-axis motion equipment and proprietary exposure column provide high throughput and excellent yields, while its scanning and dose control functions ensure accurate exposure. Its features also make it easy to use for both experienced operators and those new to wafer stepping technology.
