发明名称 METHOD OF FORMING POLYSILICON RESISTOR DURING REPLACEMENT METAL GATE PROCESS AND SEMICONDUCTOR DEVICE HAVING SAME
摘要 A method for manufacturing a semiconductor device, comprising forming a first gate stack portion on a substrate, the first gate stack portion including a first gate oxide layer and a first polysilicon layer on the first gate oxide layer, forming a second gate stack portion on the substrate, the second gate stack portion including a second gate oxide layer and a second polysilicon layer on the second gate oxide layer, forming a resistor portion on the substrate, the resistor portion including a third gate oxide layer and a third polysilicon layer on the third gate oxide layer, covering the resistor portion with a photoresist, removing respective first portions of the first and second polysilicon layers from the first and second gate stack portions, removing the photoresist from the resistor portion, and after removing the photoresist from the resistor portion, removing respective remaining portions of the first and second polysilicon layers from the first and second gate stack portions.
