Silicon dioxide, also known as silica (from the Latin silex), is a chemical compound that is an oxide of silicon with the chemical formula SiO2. It has been known since ancient times. Silica is most commonly found in nature as quartz, as well as in various living organisms.[5][6] In...
Silicon dioxidehas been used as a primarygate dielectricmaterial in metal-oxide-semiconductor field effect transistors (MOSFETs) for more than 30 years. However, as the dimension of MOSFET devices are scaled down to sub-0.1μm,higher dielectric constantmaterials are needed to allow the use of phy...
A novel gate insulator consisting of silicon dioxide (SiO2) with a thin silicon (Si) interfacial layer has been investigated for high-power microwave indium phosphide (InP) metal-insulator-semiconductor field effect transistors (MISFETs). The role of the silicon interfacial layer on the chemical na...
Silicon Dioxide Deposition by Atmospheric Pressure and Low-Temperature CVD Using TEOS and Ozone 来自 Semantic Scholar 喜欢 0 阅读量: 98 作者: K Fujino 摘要: It is demonstrated that high quality SiO 2 films can be deposited on thermally grown oxide, silicon, and aluminum steps by atmospheric...
The process involves a sequence of steps in which dopants are implanted into the silicon, thin films of silicon dioxide and silicon are grown, and metal is deposited. Between each step, the wafer is patterned so that the materials appear only where they are desired. Because transistors are a...
It is a chemical element with atomic number 14 and is abundant in the Earth's crust, accounting for about 28% of its composition. Silicon is not found in its pure form in nature, but primarily exists in compounds like silicon dioxide (SiO2), and in silicate minerals. Over time, silicon...
Dept. of Chemistry. 被引量: 0发表: 1989年 Structure analysis of silicon dioxide films formed by oxidation of silane The structure of a silicon dioxide film deposited on a silicon substrate by oxidation of silane at 340°C was analyzed by using electron‐diffraction and i... N Nagasima - ...
Then, a second lithography step is used to define the position where the trenches will be found (Figure 3F), and the silicon dioxide layer is removed by ion-beam etching (Figure 3G). Once the SiO22 has been removed, the trenches in the silicon substrate are created using the so-called ...
Lagonegro et al. [30] performed blood contact tests on silicon oxycarbide nanowires synthesized viachemical vapor deposition(CVD). It was shown that nanowires with low carbon content (13.4 at.%) promoted platelet activation similarly to flat silicon dioxide samples in porcine platelet rich plasma ...
