Semiconductor device

Abstract

A semiconductor device includes: a plurality of semiconductor units separated from each other by a trench; an insulating member disposed in the trench and over the plurality of semiconductor units; a connection electrode disposed on the insulating structure, extending laterally across the trench, and electrically connecting the plurality of semiconductor units; and a void disposed in the trench and defined by the insulating member; wherein the trench comprises a width W, and a vertical distance from a top surface of one of the plurality of semiconductor units to a bottom of the trench is L, with L/W being greater than or equal to 1.5.
