  • Publication number: 20240113217
    Abstract: An integrated circuit includes first and second trenches in a semiconductor substrate and a semiconductor mesa between the first and second trenches. A source region having a first conductivity type and a body region having an opposite second conductivity type are located within the semiconductor mesa. A trench shield is located within the first trench, and a gate electrode is over the trench shield between first and second sidewalls of the first trench. A gate dielectric is on a sidewall of the first trench between the gate electrode and the body region, and a pre-metal dielectric (PMD) layer is over the gate electrode. A gate contact through the PMD layer touches the gate electrode between the first and second sidewalls, and a trench shield contact through the PMD layer touches the trench shield between the first and second sidewalls.
