Quartz Crystal Etching, May 1954 Radio and Television News
WebThe silicon etching process is a chemical process that reduces the silicon layer to an n-dimensional structure. The sample is prepared by immersing the sample in an acidic solution and then lowered to a specific molten point. Once the sample is etched, a series of tests are performed to evaluate the etching rate, uniformity, and mask selectivity. WebJul 24, 2024 · To avoid carbon deposition on quartz crystal wafers during etching, O 2 was added to the process gas. An O 2 flow rate of 4 sccm is considered suitable because a high etching rate can be obtained without carbon deposition. Using argon instead of helium as the carrier gas in AP-PCVM will effectively solve problems such as the depletion of ...
