摘要: A method of trimming spacers includes etching a silicon oxide spacer when forming an outmost spacer, so that a silicon carbon nitride spacer contacting the gate electrode exposes an area. The exposure area of the silicon carbon nitride spacer can then be partly removed by phosphate acid. At the end of the semiconductor process, at least part of the top surface of the silicon carbon nitride spacer will be lower than the top surface of a gate electrode.
