  • Publication number: 20240136189
    Abstract: A lateral high-voltage transistor includes a semiconductor substrate, a body region formed by dopant implantation in the semiconductor substrate, the body region having a lateral boundary, a dielectric layer arranged over the semiconductor substrate, and a structured gate layer arranged over the dielectric layer. The structured gate layer overlaps the body region in the semiconductor substrate in a zone between the lateral boundary of the body region and a gate edge of the structured gate layer. The lateral boundary of the body region is a boundary defined by dopant implantation.

  • Patent number: 11887852
    Abstract: A method of manufacturing a lateral transistor is described. The method includes providing a semiconductor substrate. A dielectric layer is formed over the semiconductor substrate. A gate layer is formed over the dielectric layer. A photoresist layer is applied over the gate layer. The photoresist layer is opened by lithography to form a first opening of a first opening size in the photoresist layer. The first opening is transferred into a second opening of a second opening size, the second opening being either formed in the photoresist layer or in an auxiliary layer. A body region is formed in the semiconductor substrate by dopant implantation. Further the gate layer is structured to form a gate edge. An overlap between the structured gate layer and the body region is controlled by an offset between the first opening size and the second opening size.
