Semiconductor device
View Patent ↗The cell size is reduced and device reliability is improved for a semiconductor device including plural transistors making up a multi-channel output circuit. In a multi-channel circuit configuration, a group of transistors having a common function of plural channels are surrounded by a common trench for insulated isolation from another group of transistors having another function. The collectors of mutually adjacent transistors on the high side are commonly connected to a VH power supply, whereas the emitters of mutually adjacent transistors on the low side are commonly connected to a GND power supply.
1. A semiconductor device comprising:
a plurality of channels,
wherein a group of elements having a common function of the plurality of channels are enclosed in a common element isolation structure for insulated isolation from another group of elements, the another group of elements having another function and being enclose in another element isolation structure, and
wherein the group of elements is a group of diodes.
2. The semiconductor device according to claim 1 ,
wherein cathode regions of the group of diodes enclosed in the common element isolation structure are connected to common first potential wiring.
3. The semiconductor device according to claim 2 ,
wherein the group of diodes of mutually adjacent channels include a common cathode region.
