Abstract
A method of fabricating a semiconductor device includes providing a substrate structure comprising a semiconductor substrate of a first conductivity type, a drift layer on the semiconductor substrate, and a fin array on the drift layer and surrounded by a recess region. The fin array comprises a first row of fins and a second row of fins parallel to each other and separated from each other by a space. The first row of fins comprises a plurality of first elongated fins extending parallel to each other in a first direction. The second row of fins comprises a plurality of second elongated fins extending parallel to each other in a second direction parallel to the first direction. The method also includes epitaxially regrowing a gate layer surrounding the first and second row of fins on the drift layer and filling the recess region.
