Used ACCRETECH / TSK UF 2000 #9251570 for sale

ACCRETECH / TSK UF 2000 is a fully automated 300mm wafer prober. It is designed for use in semiconductor wafer processing, allowing for reliable measurement and testing of devices on a wafer in a high-throughput environment. This prober offers advanced alignment capabilities including real time correction of wafer misalignment and an advanced stage calibration equipment. TSK UF 2000 is suitable for use in cleanroom environments and can support up to four hot and two cold chucks as well as multiple stage assemblies, illuminating any wafer size above 200mm. ACCRETECH UF2000's motorized and pre-aligned x, y and theta stage enable precise 4-axis local scanning of samples into a variety of specialized prober cards or dedicated modules, allowing, for instance, for probing and inspection of multiple contact pins on signal devices. The prober head is equipped with four needles which can extend up to 75mm to ensure the sample probe is always in contact with the wafer surface. It also features a gridless pattern recognition system, which utilizes two image sensors to enhance precision when sampling over small sample sizes. The sample's coordinates are immediately calculated to optimize the position of the probing point. Furthermore, ACCRETECH / TSK UF2000's Align Max unit allows it to correct for subtle wafer misalignments by referencing sample grid images to a pre-defined pattern. This helps ensure the reliability of wafer testing results, especially in situations where significant variation in temperature and humidity can result in subtle shifting of sample coordinates. The prober also features a built-in stage calibration machine, providing a more accurate stage position. In terms of durability, UF2000 is designed to run non-stop with an impressive repeatability rate of 0.2μm. Additionally, the prober is built to protect the wafer from contamination as it uses a multi-stage air cushion to keep the wafer firmly in place on the chuck. In conclusion, UF 2000 is an ideal choice for semiconductor wafer processing due its combination of reliability, accuracy and precision. It has a range of features that allow it to handle the most delicate measurement and testing tasks. Thanks to its advanced features, ACCRETECH UF 2000 is a reliable piece of equipment that facilitates efficient testing and measurement of devices on wafers in a high-throughput environment.
