Publication number: 20220340429Abstract: A method for etching materials in which organic solvents are added to the etching mixture and combined in a mixing arrangement. When agitated organic materials mix with the etching agent and interact with the underlying material to form a shield around the etched areas that prevents the additional interaction of water with the newly etched areas and enables the etching of silicon oxides (SiOx) but does not oxidize Si. This method leads to milder reactions with less heat generation and avoids the safety hazards associated with conventional etching methods.Type: ApplicationFiled: April 27, 2021Publication date: October 27, 2022Applicant: BATTELLE MEMORIAL INSTITUTEInventors: Ran Yi, Ji-Guang Zhang
