Molten KOH etching was implemented on SiC substrates before growing epilayers on them. It was found that the creation of basal plane disloion (BPD) etch pits on the substrates can greatly enhance the conversion of BPDs to threading edge disloions during epitaxy, and thus low BPD density and BPD-free SiC epilayers are obtained by this method.
Epitaxy on novel substrate technology: to enable GaN-IC (e.g. GaN-on-SOI) or thicker GaN epitaxy for higher voltage range and (quasi)vertical devices GaN-IC :to develop isolation and integration modules to enable and design GaN-based integrated circuits such as high-side/low-side switches on chip.

A silicon carbide semi-insulating epitaxy layer is used to create power devices and integrated circuits having significant performance advantages over conventional devices. A silicon carbide semi-insulating layer is formed on a substrate, such as a conducting
Historically, silicon homoepitaxy employed an HCl/H 2 mixture as an in situ clean of the silicon substrate surface prior to the epitaxy process. Modern homo- and heteroepitaxy processes that employ chemical/mechanical polished substrates no longer require this step, and, instead, use a high temperature H 2 bake to remove any native oxide from the substrate surface.
