| 摘要 |
A method of fabricating a semiconductor device, including the steps of (a) forming a channel at a surface of a semiconductor substrate only in the center of a region X which physically and electrically isolates adjacent regions Y in each of which a device is to be fabricated, and (b) forming a silicon oxide layer over the region X for physically and electrically isolating the adjacent regions Y from each other. The method suppresses dimensional shift and occurrence of a stress, and further makes it difficult for the reverse narrow channel effect to occur only by adding the small number of additional steps thereto.
