Abstract: PURPOSE: A method for forming an HLR(high load register) of a rapid SRAM is provided by using a doped polysilicon, and stabilize an element operation by stably maintaining HLR's butting contact and a resistance of Vcc line at a low value. CONSTITUTION: An insulating layer is formed on a semiconductor substrate. The insulating layer is selectively etched to form a contact area. A doped polysilicon(24) having a predetermined resistance is deposited on the insulating layer by a predetermined thickness. Ion-implantation is selectively performed on a predetermined part of the doped polysilicon layer, thereby forming a load resistor layer of a predetermined resistance. Thereby, since a HLR's butting contact and a resistance of VCC line are stably maintained at a low value, a stability of an element operation and an element reliability are enhanced. Also, the post Vcc ion-implantation step can be eliminated, and thus a production cost is reduced.
