Patent ID: 7259412

Claim:
A solid state imaging device, comprising: a semiconductor substrate of a first conductivity type; a transistor provided on a surface of the substrate, the transistor including a first gate electrode provided above the substrate, a first impurity area of a second conductivity type and a second impurity area of the second conductivity type, the first impurity area and the second impurity area being formed in the surface of the substrate and sandwiching a region under the first gate electrode; a third impurity area of the second conductivity type formed in the surface of the substrate and spaced from the second impurity area at an opposite side to the first gate electrode; a fourth impurity area of the second conductivity type formed under the second impurity area and connected to the third impurity area, the fourth impurity area being out of contact with the second impurity area; a second gate electrode provided above the substrate; and a fifth impurity area of the second conductivity type formed in the surface of the substrate, the third impurity area and the fifth impurity area sandwiching a region under the second gate electrode.
