Abstract
A method for forming a MOSFET is described. The feature of this invention is that an epitaxial silicon layer with device isolation structures is formed over a substrate, wherein each device isolation structure is made of oxide. The invention need not etch the substrate for forming a device isolation structure. As a result, the invention not only prevents stress and dislocation generation and avoids leakage current, but also provides an easily method for forming a device isolation structure.
