Semiconductor device including a SRAM section and a logic circuit section |
摘要 |
A semiconductor device including a SRAM section and a logic circuit section includes: a first n-type MIS transistor including a first n-type gate electrode formed with a first gate insulating film interposed on a first element formation region of a semiconductor substrate in the SRAM section; and a second n-type MIS transistor including a second n-type gate electrode formed with a second gate insulating film interposed on a second element formation region of the semiconductor substrate in the logic circuit section. A first impurity concentration of a first n-type impurity in the first n-type gate electrode is lower than a second impurity concentration of a second n-type impurity in the second n-type gate electrode.
