Used CREST 2800DA #9288204 for sale

CREST 2800DA is a high-performance wafer processing equipment designed for use in semiconductor fabrication facilities. The system is equipped with a Delta Auto-Chamber, a 100 MHz clock source, and a scan wafer arm. The Delta Auto-Chamber is a proprietary equipment developed by CREST for processing wafers of up to 450mm in diameter. The wafers are automatically moved between the process chambers and into the pre-processing chamber, making the process highly efficient and providing quick cycle times. The triple turret-style scan wafer arm is controlled by an advanced software algorithm. This enables positioning of the wafer within +/- 0.8 mm accuracy, reducing misalignment and ensuring quality results. 2800DA has two main steps in wafer processing. In the first step, the wafer enters the pre-processing chamber where it is cleaned, primed, and made ready for the next stage. In the second step, the wafer is transferred to the Delta Auto-Chamber where two different chemicals are sprayed, through the use of a direct injection method. The chemicals are precisely mixed and sprayed onto the wafer in a uniform manner, resulting in consistent wafer quality. The process is fully automated, and up to seven chemicals can be sprayed and combined at once. CREST 2800DA unit boasts incredible precision, with fractions of micron accuracy for processing. The machine also has a vacuum handling feature which automatically controls the vacuum pressure during the process, in order to ensure the correct etch speed. Additionally, the tool has a temperature control feature that ensures uniform heating and cooling on the wafer surface. Overall, 2800DA is an advanced wafer processing asset that provides optimized performance and improved productivity. It is highly efficient, reducing misalignment and providing precise results. The model's advanced features and integrated software make it an ideal choice for those looking for high-precision wafer processing.
