Semiconductor device and method for manufacturing the same

A thin film transistor structure in which a source electrode and a drain electrode formed from a metal material are in direct contact with an oxide semiconductor film may lead to high contact resistance. One cause of high contact resistance is that a Schottky junction is formed at a contact plane between the source and drain electrodes and the oxide semiconductor film. An oxygen-deficient oxide semiconductor layer which includes crystal grains with a size of 1 nm to 10 nm and has a higher carrier concentration than the oxide semiconductor film serving as a channel formation region is provided between the oxide semiconductor film and the source and drain electrodes.

Semiconductor device

An object is to realize high performance and low power consumption in a semiconductor device having an SOI structure.

Semiconductor integrated circuit and method for manufacturing the same

A semiconductor integrated circuit according to the present invention comprises a MOS transistor formed on an SOI substrate and a subsidiary transistor provided between a body node and a drain node of the MOS transistor and sharing a gate electrode with the MOS transistor, whereby body potential of the MOS transistor is controlled by gate and drain potentials. Accumulated body charge in a non-conducting state in the semiconductor integrated circuit is extracted by a resistor formed between the body node and a source, whereby various phenomena caused by floating body effect are eliminated. Since the body potential of the MOS transistor can be varied without creating an undesirable leakage current path, and hence without limitations to supplied voltage, its threshold voltage can be made variable so as to follow change in an input signal, thereby making it possible to achieve higher speed and lower voltage operation of the semiconductor integrated circuit. According to the present invention, it is possible to eliminate floating body effect, which is the greatest problem with an SOI transistor formed on an SOI substrate, and also to achieve lower voltage and greater current operation of a transistor without posing limitations to supplied voltage and without causing the problem of leakage current.
