Method of forming a vertical diode and method of manufacturing a semiconductor device using the same
Patent number: 8241979Abstract: A method of forming a vertical diode and a method of manufacturing a semiconductor device (e.g., a semiconductor memory device such as a phase-change memory device) includes forming an insulating structure having an opening on a substrate and filling the opening with an amorphous silicon layer. A metal silicide layer is formed to contact at least a portion of the amorphous silicon layer and a polysilicon layer is then formed in the opening by crystallizing the amorphous silicon layer using the metal silicide layer. A doped polysilicon layer is formed by implanting impurities into the polysilicon layer. Thus, the polysilicon layer is formed in the opening without performing a selective epitaxial growth (SEG) process, so that electrical characteristics of the diode may be improved.Type: GrantFiled: August 20, 2010Date of Patent: August 14, 2012Assignee: Samsung Electronics Co., Ltd.Inventors: Sang-Jin Park, Kong-Soo Lee, Yong-Woo Hyung, Young-Sub You, Jae-Jong Han -
