A process for forming low resistance contacts between silicide areas and upper level polysilicon interconnect layers including a specific doping technique that provides solid low resistance contacts between a lower level of a silicided area and an upper level polysilicon interconnect. The doping technique combines a doping implant of the upper level polysilicon and an ion-mixing implant into a single implant thereby achieving a low resistive implant which also reduces processing steps. |
