Plasma Etching of Deep High-Aspect Ratio Features Into …

This paper reports research performed on developing and optimizing a process recipe for the plasma etching of deep high-aspect ratio features into silicon carbide (SiC) material using an inductively-coupled plasma reactive-ion etch process. We performed a design of experiments (DOE) wherein the etch recipe parameters having the most impact on the etch process were varied over fixed ranges of

Highly selective silicon nitride to silicon oxide process in Oxford …

CNF TCN, page 5 Background (con’t) • N2 is an important etch product in silicon nitride etching. • Desorption of nitrogen can often be the limiting factor in nitride etching. • The addition of N2 to the plasma etch chemistry can enhance the nitride etch rate.

Chemical contribution of oxygen to silicon carbide …

This paper deals with the influence of the oxygen additive on the fluorinated plasma etch rate of silicon carbide. The assumption according to which the oxygen has a direct contribution to silicon carbide etching, by chemical reaction with carbon atoms, is generally reported in the literature. Our etching experiments are performed in a distributed electron cyclotron resonance reactor, on both

Formation of three-dimensional structures in the silicon …

A survey dealing with the technology of the formation of three-dimensional structures in silicon carbide substrates is presented. As for technology, this problem can be solved by variational ion-stimulated plasma-chemical etching, and most successfully by the source of inductively coupled plasma (ICP). Silicon carbide consists of silicon and carbon that form volatile fluorides in the reaction

Ohmic contact formation on inductively coupled plasma …

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.
