发明名称 Method for fabricating semiconductor memory device
摘要 A method for manufacturing a semiconductor device comprises forming a first spacer layer at sidewalls of one or more gate electrodes, forming a trench by etching an isolation insulating layer exposed between the gate electrodes, forming a second spacer layer on sidewalls of the gate electrodes and an inner surface of the trench and forming an interlayer insulating layer between the gate electrodes.
