POLYSILICON RESISTOR STRUCTURES - A simplified explanation of the abstract

This abstract first appeared for US patent application 18516311 titled 'POLYSILICON RESISTOR STRUCTURES

Simplified Explanation

The present disclosure describes a method for forming polysilicon resistors with high-k dielectrics and polysilicon gate electrodes. The method includes depositing a resistor stack on a substrate having spaced apart first and second isolation regions. Further, the method includes patterning the resistor stack to form a polysilicon resistor structure on the first isolation region and a gate structure between the first and second isolation regions, and doping the polysilicon resistor structure to form a doped layer in the polysilicon layer of the polysilicon resistor structure and source-drain regions in the substrate adjacent to the gate structure. Also, the method includes replacing the polysilicon layer in the gate structure with a metal gate electrode to form a transistor structure.

  • Deposit resistor stack on substrate with isolation regions
  • Pattern resistor stack to form polysilicon resistor and gate structures
  • Dope polysilicon resistor structure and source-drain regions
  • Replace polysilicon layer in gate structure with metal gate electrode
