摘要:
A method of manufacturing a semiconductor device comprises forming a trench in a semiconductor substrate, forming a first insulating film having a first recessed portion in the trench, forming a coating film so as to fill the first recessed portion therewith, transforming the coating film into a second insulating film, planarizing the second insulating film to expose the first insulating film and the second insulating film, removing at least the second insulating film from the first recessed portion to moderate an aspect ratio for the first recessed portion formed in the trench, thereby forming a second recessed portion therein, and forming a third insulating film on a surface of the semiconductor substrate so as to fill the second recessed portion therewith.

摘要:
A p-type silicon substrate has an element isolation region of an STI structure formed therein. A transistor region isolated by the isolation region has a n-type source/drain diffusion layer. Further, a p-channel impurity layer is formed substantially only in its channel region for controlling its threshold voltage (Vth). A gate insulator film consisting of a high dielectric film is formed on the channel region with an Si3N4 film interposed therebetween. A metal gate electrode having its bottom and side surfaces covered with the gate insulator film is provided in a self-alignment manner with respect to the source/drain diffusion layer.

摘要:
In using an epitaxial growth method to selectively grow on a silicon substrate an epitaxial layer on which an element is to be formed, the epitaxial layer is formed so as to extend upward above a thermal oxide film that is an element isolating insulating film, in order to prevent formation of facets. Subsequently, unwanted portions of the epitaxial layer are removed by means of CMP to complete an STI element isolating structure.
