We report on the investigation of ohmic contact formation using sputtered titanium-tungsten contacts on an inductively coupled plasma (ICP) etch-damaged 4H-SiC surface. Transfer length method (TLM) measurements were performed to characterize how ICP-etch damage affects the performance of ohmic contacts to silicon carbide.
Carbide-derived carbon (CDC), also known as tunable nanoporous carbon, is the common term for carbon materials derived from carbide precursors, such as binary (e.g. SiC, TiC), or ternary carbides, also known as MAX phases (e.g., Ti 2 AlC, Ti 3 SiC 2). CDCs
Since CVD silicon carbide can be used in very thin sections, its low mass can improve throughput while it improves the use of space in crowded processing tools. We believe low resistivity CVD silicon carbide will revolutionize the deposition and etch processes.
4/12/2015· By increasing the etch temperature from 1100 C to 1200 C at an O 2 flow rate of 20 sccm, the etch rate increased by 63% (from 1.9 μm/min to 3.1 …
Silicon nitride has a negligible etch rate in TMAH; the etch rate for silicon dioxide in TMAH varies with the quality of the film, but is generally on the order of 0.1 nm/minute. Showing page 1. Found 393 sentences matching phrase "etch rate".Found in 10 ms.
Color centers in silicon carbide have recently attracted broad interest as high bright single photon sources and defect spins with long coherence time at room temperature. There have been several methods to generate silicon vacancy defects with excellent spin

The plasma etch is performed at a low pressure, 5 mtorr, which together with a high gas throughput, provides for rapid removal of the gaseous etch products. The lateral topology of the SiC microstructure is defined by a thin film of etch-resistant material, such as indium-tin-oxide, which is patterned using conventional photolithographic processes.
Silicon carbide (SiC) substrates are often used in the design of GaN-based electronics due to its high thermal conductivity (370 W/m-K) which can be leveraged to reduced device channel temperatures.

In this paper, a review of the current understanding and practice of reactive ion etch-ing of SiC is presented. We concentrate on the fluorine-based RIE of 6H-SiC, the most widely used polytype. However, some results in the plasma-assisted etching of 3C and 4H
For use in plasma etch environments, the silicon carbide etches more slowly than silicon, thus a protective layer of CVD SiC is coated on the surface. This protective coating can be placed on both large surface areas and on the inside walls of tubes and partial enclosures.
