Buffered chemical polishing
WebThere are several different methods that can be used to polish GaAs wafers, including chemical-mechanical polishing (CMP), buffered oxide etch (BOE), and mechanical polishing. In chemical-mechanical polishing, the wafer is placed on a rotating platform and a slurry of abrasive particles is applied to the surface. The abrasive particles remove ...

For the weak base ammonia (NH 3), the value of K b is 1.8x10-5, implying that the K a for the dissociation of its conjugate acid, NH 4 +, is K w /K b =10-14 /1.8x10-5 = 5.6x10-10. Thus, the pK a for NH 4 + = 9.25, so buffers using NH 4 + /NH 3 will work
