Abstract
Abstract In connection with the fabrication of an integrated circuit, a method for simultaneously completing the formation of a contact, an interconnect, a gate and a source or drain is disclosed. An integrated circuit field effect structure wherein a diffused silicon area is connected directly to a polysilicon member by conductive silicon and more specifically the source or drain of one device is directly and continuously connected to the gate of an adjacent device by a conductive silicon member.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
170 words
An integrated circuit which includes a plurality of gate type devices wherein each such device includes a separated source and drain in a semiconductor body and a gate spaced insulatively above and between the source and drain, the improvement comprises: a silicon contact member to provide electrical coupling to one of said source and drain in a first gate type device, said silicon contact member being contiguous to said semiconductor body at one of said source and drain in said first gate type device; a silicon gate member to form said gate insulatively spaced above and between the source and drain of a second gate type device; and a silicon interconnect member to provide electrical coupling between said silicon gate member and said silicon contact member, said interconnect member being integrated with and contiguous to said contact and gate members, whereby one of said source and drain of said first gate type device is electrically coupled to said gate of said second gate type device and high density circuits achieved.
Claim 2
Dependent Claim
170 words
An integrated circuit which includes a plurality of gate type devices wherein each such device includes a separated source and drain in a semiconductor body and a gate spaced insulatively above and between the source and drain, the improvement comprises: a silicon contact member to provide electrical coupling to one of said source and drain in a first gate type device, said silicon contact member being contiguous to said semiconductor body at one of said source and drain in said first gate type device; a silicon gate member to form said gate insulatively spaced above and between the source and drain of a second gate type device; and a silicon interconnect member to provide electrical coupling between said silicon gate member and said silicon contact member, said interconnect member being integrated with and contiguous to said contact and gate members, whereby one of said source and drain of said first gate type device is electrically coupled to said gate of said second gate type device and high density circuits achieved.
Claim 3
Dependent Claim
31 words
The improvement of claim 1 wherein said silicon contact, gate and interconnect members are of the same conduCtivity type material as said source and drain of said first gate type device.
Claim 4
Dependent Claim
21 words
The improvement of claim 1 wherein said silicon contact, gate and interconnect members are primarily of polycrystalline silicon having impurities therein.
