Patent JP-H0883838-A (JP)
Title: Manufacture of semiconductor device
Inventor: SATO TSUKASA
IPC: H01L23/522
Filed: 1994-09-09
Abstract: PURPOSE: To prevent the short of a contact hole at the time of formation of interconnects which is caused by higher integration and fineness by forming polycrystalline silicon layers in two levels in and on the fringe of the contact hole which becomes a connection between a semiconductor substrate and an upper interconnect. CONSTITUTION: In and on the fringe of a contact hole 5 which becomes a connection between a semiconductor substrate 1 and an upper interconnect film 10, a two-layer pad electrode which, consisting of a first polysilicon film 6 and a second polysilicon film 8, connects the upper interconnect film 10 and the semiconductor substrate 1 is formed. By using the structure that the two pad electrode layers which are constituted of the polysilicon layers are put at the contact section between the metal interconnect 10 and the substrate 10, the contact can be secured even if there is a little deviation in position. Due to the existence of two interlayer insulating films 4, 7, the pad electrode layers are prevented from being brought into contact with an adjacent electrode 3.  Due to this structure, there is no contact between a wiring pattern of a circuit in a first layer and the metal interconnect and thereby a semiconductor device can be free from bad contact.
