Title:
SEMICONDUCTOR DEVICE AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
Japanese Patent JP2007165480
Kind Code:
A
Abstract:

To provide a semiconductor device which has a transistor of a salicide structure and a transistor of a nonsalicide structure that are formed on one board, and prevents an increase in the contact resistance of the transistor of the salicide structure that is caused by a protective film formed upon forming the salicide structure.

The semiconductor device includes a first MIS (metal insulator semiconductor) transistor 51 of a nonsalicide structure, and a second MIS transistor 52 of a salicide structure. Both transistors 51 and 52 are formed on a board 11 made of silicon. The first MIS transistor 51 has a first gate electrode 14A made of silicon, a first side wall 15A, a first source/drain 16A, and a plasma reactant film 18 grown under a plasma atmosphere which plasma reactant film 18 covers the upper surface of the first gate electrode 14A and the upper surface of the first source/drain 16A.
