发明名称 PROCESS FLOW FOR REPLACEMENT METAL GATE TRANSISTORS
摘要 <p>A replacement metal gate transistor and methods of forming replacement metal gate transistors are described. Various examples provide methods of manufacturing a replacement metal gate transistor that includes depositing a dielectric layer into a trench, wherein the dielectric layer is deposited onto the bottom of the trench and the sidewalls of the trench, depositing a first metal layer into the trench, wherein the first metal layer is deposited onto the bottom of the trench and the sidewalls of the trench over the dielectric layer, depositing a second metal layer into the trench, wherein the second metal layer is deposited onto the bottom of the trench and the sidewalls of the trench over the first metal layer, removing at least a portion of the second metal layer from the sidewalls of the trench, and depositing a conducting layer into the trench. Other embodiments are disclosed and claimed.</p>
