Latest Patents

Akiya's latest patents include a Constant Current Circuit and a Semiconductor Integrated Circuit. The Constant Current Circuit patent describes a design where a drain terminal is connected to an output terminal of a current. A gate voltage operable in a saturation region is applied to a source-grounded transistor. This design features an increase current generating circuit that produces an increase current equivalent to the increase of a current due to the channel length modulation effect of the transistor. Additionally, a current mirror circuit generates a current that matches the value of the increase current and supplies it to the drain terminal of the transistor.

The Semiconductor Integrated Circuit patent details an insulated gate type semiconductor device. This device consists of a semiconductor layer serving as an active region, isolated from a semiconductor substrate by a substrate isolation insulating film. A T-shaped gate electrode is comprised of a trunk-shaped main gate electrode and a crosspiece-shaped conductor pattern on the semiconductor layer. The design ensures that the thickness of the gate insulating film directly under the crosspiece-shaped conductor pattern is greater than that under the main gate electrode. This innovation helps prevent short-circuits between electrodes, short-circuits between separators, and reduces parasitic capacitance.
