Patent
Semiconductor integrated circuit unit
TL;DR: A semiconductor integrated circuit unit, suitable for the control of a motor, has an integrated structure within the same semiconductor substrate, comprising an inverter circuit, drive circuits for driving the switching elements of the inverter circuits, an internal power source circuit for supplying power to the drive circuits which drive the upper arm side of the inverted circuit, and a logical circuit for transmitting a signal to drive circuits that drive the lower arm of an inverted circuit as discussed by the authors.
Patent
Trench gate type semiconductor device with current sensing cell
TL;DR: In this article, a trench gate type semiconductor device with a current sensing cell is composed so that the orientation of crystal face at side walls of trenches forming channels of trench gates in a main cell is equal or almost equal, or equivalent or almost equivalent to the orientation in the sensing cell.
