Publication number: 20240128313Abstract: A method includes providing a substrate, forming a patterned hard mask layer over the substrate, etching the patterned hard mask layer to form a hole that penetrates the patterned hard mask layer, forming a barrier portion in the hole, removing the patterned hard mask layer, and forming a gate structure over the substrate. Formation of the gate structure includes forming a dielectric body portion on the substrate. The barrier portion that is thicker than the dielectric body portion adjoins one end of the dielectric body portion. The dielectric body portion and the barrier portion are collectively referred to as a gate dielectric layer. Formation of the gate structure further includes forming a gate electrode on the gate dielectric layer and forming gate spacers on opposite sidewalls of the gate electrode. During formation of the gate spacers, a portion of the barrier portion is removed to form a recessed corner.Type: ApplicationFiled: October 17, 2022Publication date: April 18, 2024Applicant: Vanguard International Semiconductor CorporationInventors: Tse-Hsiao LIU, Chih-Wei LIN, Po-Hao CHIU, Pi-Kuang CHUANG, Ching-Yi HSU

Publication number: 20240088246Abstract: Various embodiments of the present application are directed towards a control gate layout to improve an etch process window for word lines. In some embodiments, an integrated chip comprises a memory array, an erase gate, a word line, and a control gate. The memory array comprises a plurality of cells in a plurality of rows and a plurality of columns. The erase gate and the word line are elongated in parallel along a row of the memory array. The control gate is elongated along the row and is between and borders the erase gate and the word line. Further, the control gate has a pad region protruding towards the erase gate and the word line. Because the pad region protrudes towards the erase gate and the word line, a width of the pad region is spread between word-line and erase-gate sides of the control gate.Type: ApplicationFiled: November 16, 2023Publication date: March 14, 2024Inventors: Yu-Ling Hsu, Ping-Cheng Li, Hung-Ling Shih, Po-Wei Liu, Wen-Tuo Huang, Yong-Shiuan Tsair, Chia-Sheng Lin, Shih Kuang Yang
