Patent ID: 7534553

Claim:
A method for fabricating a semiconductor device, comprising: preparing a substrate defined as active regions and inactive regions and provided with a plurality of conductive patterns; forming a buffer layer over the plurality of conductive patterns; forming an organic material having fluidity better than that of a photoresist layer on the buffer layer; flowing the organic material between the conductive patterns through a thermal treatment process, thereby filling a predeterminded portion of each gap between the conductive patterns to prevent the formation of voids; forming the photoresist layer without voids on the portions of the organic material and the buffer layer between the plurality of conductive patterns; forming a plurality of photoresist patterns, opening the active regions through a photo-exposure process and a developing process, wherein the organic material remains over the active regions, and the photoresist patterns and the organic material remain over the inactive regions; and performing an ion-implantation process using the plurality of photoresist patterns, thereby forming a plurality of junction regions in the active regions of the substrate.
