The system includes multiple processing stations accessible by a transfer device, including a measuring station to optically measure the thickness of a substrate, a controller to calculate an etch recipe for the substrate, in real time, and cause a single wafer wet etching station to etch the substrate according to the recipe. In addition, the system can measure the after etch thickness and calculate etch recipes, in real time, as a function of the final measurements of a previous substrate. The system can also include an in situ end point detection device for detecting the TSV reveal point while etching TSVs substrates. The system provides an automated solution to adjust etch recipe parameters in real time according to feedback concerning previously etched wafers and precisely control the TSV reveal height and etch duration using end point detection."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for performing a wet etching process","description":"A system and method for performing a wet etching process is disclosed.
