temperature develops layer over the surface of SiC and protects it from further catastrophic oxidation to SiO occurred at higher temperatures. Such pro- tective action continues up to the melting point of SiO 2 (1996K) [28]. A number of studies were performed on the two modes of oxidation ...
METHOD FOR OXIDATION OF A SILICON SUBSTRATEMethod for oxidation of a silicon substrate under ultrahigh vacuum base conditions, wherein the substrate undergoes a number of oxidation cycles with exposure to oxygen and heat treatment for converting the adsorbed oxygen into silicon oxide....
A semiconductor wafer containing a silicon nitride layer to be oxidized according to the present invention can be heated in any of a number of ways--the type of heating used is not critical. In the preferred embodiment, the wafer is heated by rapid thermal annealing (RTA). In other approach...
Liquid-phase oxidants can be used to produce abundant oxygen-containing functional groups on the surface of carbon materials. (1) H2SO4. As a strong oxidizing acid, changes in the dosage of H2SO4 affect the number of oxygen-containing functional groups of carbon materials, while also ...
Oxidation tests were carried out in samples from an ultra low carbon and two silicon bearing steels to determine the distribution and morphology of the oxide species present. The ultra low carbon steel was oxidized for short periods of time within a chamber designed to obtain thin oxide layers ...
The sustainable increase in the number of integrated basic components on a chip is becoming a significant challenge for the advancement of the internet of things (IoT) technology, especially in the post-Moore era. In terms of the scaling down limitation of silicon-based materials, two-dimensional...
