Molecular models of the different molecules active in Piranha solution: peroxysulfuric acid (H 2 SO 5) and hydrogen peroxide (H 2 O 2). Piranha solution, also known as piranha etch, is a mixture of sulfuric acid (H 2 SO 4) and hydrogen peroxide (H 2 O 2). The resulting mixture is used to clean organic residues off substrates, for example ...
The RCA clean is a standard set of wafer cleaning steps which need to be performed before high-temperature processing steps (oxidation, diffusion, CVD) of silicon wafers in semiconductor manufacturing. Werner Kern developed the basic procedure in 1965 while working for RCA, the Radio Corporation of America.
Etching tanks used to perform Piranha, hydrofluoric acid or RCA clean on 4-inch wafer batches at LAAS technological facility in Toulouse, France. Etching is used in microfabrication to chemically remove layers from the surface of a wafer during manufacturing. Etching is a critically important process module in fabrication, and every wafer ...

SVM (Silicon Valley Microelectronics, Inc.) is a privately held California corporation which provides silicon wafers and services to the semiconductor and solar industries. SVM sells a variety of wafer diameters, including 100mm, 200mm, and 300mm Prime and Test device quality wafers.
He pulled out an old map published by the International Atomic Energy Agency that noted from 1946 to 1970, more than 56,000 barrels of radioactive waste had been dumped into the Pacific Ocean on ...
Oxidation of silicon is a common and frequent step in the manufacture of integrated circuits (IC). The goal of oxidation is to grow a high quality, uniform oxide layer on a silicon substrate. During oxidation, a chemical reaction between the oxidants and the silicon atoms produces a layer of oxide on the silicon surface of the wafer.
Piranha solution in particular constitutes quite a harsh treatment that can potentially damage the integrity of the silicon surface. Finlayson-Pitts et al. investigated the effect of certain treatments on silicon and concluded that both the roughness (3-5 Å) and the presence of scattered large particles were preserved after 1 cycle of plasma ...
