Abstract:
1. A semiconductor device comprising: a first inverter disposed in a first row and a first column, including a second inverter disposed in a second row and a second column, including a second access transistor disposed in the first row and the second column, including a first access transistor disposed in the second row and the first column, including an upper surface of the first gate line is positioned lower than an upper end of the first second-conductivity-type high-concentration semiconductor, an upper surface of the second gate line is positioned lower than an upper end of the third second-conductivity-type high-concentration semiconductor, and a length of a portion between the first first-conductivity-type high-concentration semiconductor and the second first-conductivity-type high-concentration semiconductor of the first driver transistor and a length of a portion between the third first-conductivity-type high-concentration semiconductor and the fourth first-conductivity-type high-concentration semiconductor of the second driver transistor are shorter than a length of a portion between the seventh first-conductivity-type high-concentration semiconductor and the eighth first-conductivity-type high-concentration semiconductor of the first access transistor and a length of a portion between the fifth first-conductivity-type high-concentration semiconductor and the sixth first-conductivity-type high-concentration semiconductor of the second access transistor.
