Patent number: 10553502Abstract: A system and method for performing a wet etching process is disclosed. The system includes multiple processing stations accessible by a transfer device, including a measuring station to optically measure the thickness of a wafer before and after each etching steps in the process. The system also includes a controller to analyze the thickness measurements in view of a target wafer profile and generate an etch recipe, dynamically and in real time, for each etching step. In addition, the process controller can cause a single wafer wet etching station to etch the wafer according to the generated etching recipes. In addition, the system can, based on the pre and post-etch thickness measurements and target etch profile, generate and/or refine the etch recipes.Type: GrantFiled: June 8, 2018Date of Patent: February 4, 2020Assignee: VEECO PRECISION SURFACE PROCESSING LLCInventors: Laura Mauer, John Taddei, John Clark, Elena Lawrence, Eric Kurt Zwirnmann, David A.

Patent number: 10541180Abstract: A system and method are provided for etching semiconductor wafers (integrated circuit substrates) with advanced packaging using a two-step wet etching process. The first etch step uses an etchant that is non-selective to at least the wafer material (silicon) and metals, such as copper and titanium, that are present in the wafer. The second etch step uses an etchant that is selective to the wafer material (silicon) and has low selectivity for the metals, thereby leaving them at least substantially intact.Type: GrantFiled: February 23, 2018Date of Patent: January 21, 2020Assignee: VEECO PRECISION SURFACE PROCESSING LLCInventors: Laura Mauer, John Taddei, John Clark, Kenji Nulman
