WebSemiconductor Lithography (Photolithography) - The Basic Process. The fabrication of an integrated circuit (IC) requires a variety of physical and chemical processes performed on a semiconductor (e.g., silicon) substrate. In general, the various processes used to make an IC fall into three categories: film deposition, patterning, and ... WebWet chemical etching is the most common strategy for glass microfabrication. In most cases, hydrofluoric acid (HF) is used as the main etchant for any type of silicate glass. … WebBut as the HF is depleted (used up) from the solution the etch rate would change. Thus, a Buffering solution is added that controls the HF concentration as: NH 4 F NH 3 HF The HF concentration remains “saturated”. As HF is consumed etching SiO 2, the above reaction replaces the HF, keeping the etch rate constant. Wet Chemical Etching: mla research tool
