Abstract
A semiconductor device includes: a substrate having a cell region and a peripheral region; a thyristor on the cell region; a MOS transistor on the peripheral region; a first shallow trench isolation (STI) between the thyristor and the MOS transistor; and a second STI between the first STI and the MOS transistor. The thyristor further includes: a first semiconductor layer, a second semiconductor layer, a third semiconductor layer, and a fourth semiconductor layer on the cell region; patterned metal layers in the first semiconductor layer; vertical dielectric patterns on the patterned metal layers; and first contact plugs on the fourth semiconductor layer.
