Semiconductor device with gate structure and oxide layer
A recently granted patent (Publication Number: US12002883B2) discloses a semiconductor device comprising a semiconductor substrate with a gate structure, drift regions, and source/drain regions. The device includes a unique gate oxide layer with distinct portions - a first portion between the gate structure and the substrate in a vertical direction, and a second portion between the first portion and the source/drain region in a horizontal direction. A spacer structure on the gate oxide layer contacts a depressed top surface of the second portion, with the bottom of the first portion higher than the bottom of the second portion in the vertical direction.
Furthermore, the patent describes additional features such as multiple drift regions and source/drain regions on opposite sides of the substrate under the gate structure. The gate oxide layer includes a third portion between the first portion and the second source/drain region, with a depressed top surface. The bottom of the first portion is higher than the bottom of the third portion in the vertical direction. These innovative design elements aim to enhance the performance and efficiency of the semiconductor device, showcasing advancements in semiconductor technology.
