Abstract

Official abstract text for this publication.

A method of forming a Fin-FET is provided. A substrate is provided, then a mask layer is formed thereabove. A first trench is formed in the substrate and the mask layer. A semiconductor layer is formed in the first trench. Next, the mask layer is removed such that the semi-conductive layer becomes a fin structure embedded in the substrate and protruded above the substrate. Finally, a gate layer is formed on the fin structure.

First claim

Opening claim text (preview).

What is claimed is: 1. A method of forming a Fin-FET, comprising: providing a substrate; forming a mask layer on the substrate; forming a first trench having an acute angle less than 30 degrees in the mask layer and the substrate; forming a semiconductor layer in the first trench; completely removing the mask layer such that the semiconductor layer becomes a fin structure embedded in the substrate and protruding from the substrate; and forming a gate layer on the fin str…
