Abstract:
A method of forming a contact in an integrated circuit, comprising the steps of:(a) forming first and second insulated gates on a substrate;(b) implanting a first dose of dopants into said substrate between said first and second gates using said first and second gates as at least a part of the implant mask;(c) forming a first sidewall spacer on said first gate and adjacent said second gate;(d) forming a second sidewall spacer on said second gate and adjacent said first gate;(e) implanting a second dose of dopants into said substrate between said first and second gates using said first and second gates plus said first and second sidewall spacers as at least a part of the implant mask;(f) removing both said first and second sidewall spacers; and(g) forming a contact to said substrate between said first and second gates.
