The insulating layer has a contact hole which exposes the conducting region. Next, a silicon-containing metallization layer and a silicon-free metallization layer are sequentially formed on the insulating layer such that the silicon-containing metallization layer contacts the conducting region through the contact hole. After heat-treating the substrate, the two metallization layers are patterned.Type: GrantFiled: September 29, 1997Date of Patent: December 12, 2000Assignee: Hyundai Electronics Industries Co., Ltd.Inventor: Seong-Wook Yoo
