Publication number: 20250089324Abstract: A gate oxide layer for a high voltage transistor is formed using methods that avoid thinning in the corners of the gate oxide layer. A recess is formed in a silicon substrate. The exposed surfaces of the recess are thermally oxidized to form a thermal oxide layer of the gate oxide layer. A high temperature oxide layer of the gate oxide layer is then formed within the exposed surfaces of the recess by chemical vapor deposition. The combination of the thermal oxide layer and the high temperature oxide layer results in a gate oxide layer that does not exhibit the double hump phenomenon in the drain current vs. gate voltage curve. The high temperature oxide layer may include a rim that extends out of the recess.Type: ApplicationFiled: September 8, 2023Publication date: March 13, 2025Inventors: Jhu-Min Song, Yi-Kai Ciou, Chi-Te Lin, Yi-Huan Chen, Szu-Hsien Liu, Chan-Yu Hung, Chien-Chih Chou, Fei-Yun Chen

Publication number: 20250006731Abstract: A high voltage transistor may include a plurality of source/drain regions, a gate structure, and a gate oxide layer that enables the gate structure to selectively control a channel region between the source/drain regions. The gate oxide layer may extend laterally outward toward one or more of the plurality of source/drain regions such that at least a portion of the gate oxide layer is not under the gate structure. The gate oxide layer extending laterally outward from under the gate structure enables the gate oxide layer to be used as a self-aligned structure for forming the source/drain regions of the high voltage transistor. In particular, the gate oxide layer extending laterally outward from under the gate structure enables the gate oxide layer to be used to form the source/drain regions at a greater spacing from the gate structure without the use of additional implant masks when forming the source/drain regions.Type: ApplicationFiled: June 30, 2023Publication date: January 2, 2025Inventors: Kau-Chu LIN, Chan-yu HUNG, Fei-Yun CHEN
