WebPoly-silicon etching dimensions show a linearly proportional relationship with resist-trimming time; thus, the trimming amount can be controlled according to time. Fig. 8—35-nm Poly-silicon Gate Shape Formed by Resist Trimming. When the case 1 etching flow (see Fig. 6) is used, an initial resist-pattern dimension of 101.5 nm can be processed to a WebBecause of this, gate linewidth control is viewed by many as the most critical application for integrated metrology on etch systems. For several years, integrated metrology and wafer-level process control have been used in high volume manufacturing of 90 and 65nm polysilicon gate etch [1], [3], [17], [22].
