A novel method for etching trenches in silicon carbide | …

In this paper, a novel trench etching technique for silicon carbide is described. In this technique, ion implantation is used to first create an amorphous silicon carbide region. The amorphous layer is then etched away by wet chemical etching. Trenches of 0.3 to 0.8 μ have been obtained using a single implantaion/etching step. It has been demonstrated that deeper trenches can be obtained by

Dry etching - Wikipedia

Dry etching refers to the removal of material, typically a masked pattern of semiconductor material, by exposing the material to a boardment of ions (usually a plasma of reactive gases such as fluorocarbons, oxygen, chlorine, boron trichloride; sometimes with addition of nitrogen, argon, helium and other gases) that dislodge portions of the material from the exposed surface.

Etching with a hard mask - Texas Powerful Smart

The Modelization of the Wet Etching Rate by the …

This “theory” stipulates that the etch rate in doped SiO2 can be predicted by knowing the etch rate in nondoped one. Thus, we have extracted an entity what we called "segregation proportionality", proportional to the diffusion-segregation boron and phosphorus distributions in the silicon dioxide-silicon, and which can be physically and chemically explained.
