Abstract
Description
technical field
[0001] The application relates to a semiconductor cleaning agent and a preparation method thereof, belonging to the technical field of semiconductor cleaning. Background technique
[0002] In the production of silicon transistors and integrated circuits, almost every process has the problem of cleaning silicon wafers. The quality of silicon wafers has a serious impact on device performance. Improper handling may cause all silicon wafers to be scrapped and fail to produce qualified products. Products, or manufactured products have poor performance, poor stability and reliability.
[0003] After a series of processing of the silicon material, the surface of the silicon wafer will form sand, cutting abrasives, fingerprints and metal ions. The purpose of cleaning is to remove pollutants such as particles, metal ions and organic substances on the surface of the silicon wafer, so that the surface of the silicon wafer can reach No corrosion, oxidation, no residue a...
