Filed: 1987-10-15
Abstract: PURPOSE:To improve mutual conductance and to prevent property variations by forming a sidewall of a gate electrode only on the side of the drain region by a selective anisotropic etching after depositing an insulating film. CONSTITUTION:A sidewall 4 consisting of an insulating film is formed only on the side of a drain region 12 of a gate electrode 3 by an anisotropic etching. When removing the insulating film on a source region 11, no sidewall will be formed by the anisotropic etching with masking the drain region 12. Thus, a double structure where a lightly doped impurity region 5 and a heavily doped impurity region 6 are formed can be provided only on the drain region 12. According to the constitution, the mutual conductance is improved, and semiconductor integrated circuit devices including LDD structured MOSFETs whose 'on' state source-drain series resistance is stable with high patterning accuracy can be prepared with high reproducibility.
