Patent number: 11948278Abstract: An image quality improvement method and an image processing apparatus using the same are provided. Denoising filtering is performed to an original image by a filter to obtain a preliminary processing image. The preliminary processing image is input to a multi-stage convolutional network model to generate an optimization image through the multi-stage convolutional network model. The multi-stage convolutional network model includes multiple convolutional network sub-models, and these convolutional network sub-models respectively correspond to different network architectures.Type: GrantFiled: August 18, 2021Date of Patent: April 2, 2024Assignee: National Chengchi UniversityInventors: Yan-Tsung Peng, Sha-Wo Huang, Ming-Hao Lin, Chin-Hsien Wu, Chun-Lin Tang

Patent number: 10566291Abstract: This disclosure relates to a structure for aligning layers of an integrated circuit (IC) structure that may include a first dielectric layer positioned above a semiconductor substrate having one or more active devices, a trench stop layer positioned above the first dielectric layer, a second dielectric layer positioned above the trench stop layer, and a plurality of metal-filled marking trenches extending vertically through the second dielectric layer and the trench stop layer and at least partially into the first dielectric layer. The metal-filled trenches are electrically isolated from any active devices contained in the IC.Type: GrantFiled: February 18, 2018Date of Patent: February 18, 2020Assignee: GLOBALFOUNDRIES INC.Inventors: Ming Hao Tang, Yuping Ren, Rui Chen, Bradley Morgenfeld, Zheng G.

Patent number: 10453751Abstract: A tone inversion method for integrated circuit (IC) fabrication includes providing a substrate with a layer of amorphous carbon over the substrate and a patterning layer over the amorphous carbon layer. The patterning layer is etched to define a first pattern of raised structures and a complementary recessed pattern that is filled with a layer of image reverse material. The first pattern of raised structures is then removed to define a second pattern of structures comprising the image reverse material. A selective etching step is used to transfer the second pattern into a dielectric layer disposed between the layer of amorphous carbon and the substrate.Type: GrantFiled: February 14, 2017Date of Patent: October 22, 2019Assignee: GLOBALFOUNDRIES INC.Inventors: Xiaofeng Qiu, Michael V. Aquilino, Patrick D. Carpenter, Jessica Dechene, Ming Hao Tang, Haigou Huang, Huy Cao
