Abstract
An integrated circuit device includes a high-speed I/F circuit block which transfers data through a serial bus, and a driver logic circuit block which generates a display control signal. A first-conductivity-type transistor included in the high-speed I/F circuit block is formed in a second-conductivity-type well, and a second-conductivity-type transistor included in the high-speed I/F circuit block is formed in a first-conductivity-type well formed in a second-conductivity-type substrate to enclose the second-conductivity-type well. A first-conductivity-type transistor and a second-conductivity-type transistor included in the driver logic circuit block are formed in a region other than a region of the first-conductivity-type well for the high-speed interface circuit block.
