  • Publication number: 20240290882
    Abstract: A semiconductor device includes: a silicon layer having a frontside and an electrically insulated backside; a first trench extending through the silicon layer from the frontside to the electrically insulated backside and laterally isolating a first region of the silicon layer; an electrically conductive material in the first trench; a dielectric material separating the electrically conductive material from silicon material of the silicon layer; and a plurality of silicon plugs laterally surrounded by the dielectric material and dividing the electrically conductive material into a plurality of separate segments in the first trench. Additional embodiments of semiconductor devices and methods for manufacturing the semiconductor devices are also described.
