Abstract
A semiconductor device can be formed without use of an STI process. An insulating layer is formed over a semiconductor body. Portions of the insulating layer are removed to expose the semiconductor body, e.g., to expose bare silicon. A semiconductor material, e.g., silicon, is grown over the exposed semiconductor body. A device, such as a transistor, can then be formed in the grown semiconductor material.
