Patent number: 11947134Abstract: A device is provided to generate a three-dimensional (3D) real image. A display panel is divided into several sub-areas for emitting scenes. Through a projecting lens-array unit, the scenes enter a fusion lens unit to form a real image of light field at a position beyond common barrier. Through an eyepiece unit, the image is emitted to human eye. Thus, the present invention provides a device for near-eye viewing, which reduces existing human-eye vergence accommodation conflict (VAC) in most augmented reality and mixed reality devices. Therein, the display of near-eye light field is a process of light-field reproduction, which merges the scenes and reduces aberration.Type: GrantFiled: January 22, 2021Date of Patent: April 2, 2024Assignee: National Taiwan UniversityInventors: Jiun-Woei Huang, Chang-Le Liu, Hong-Ming Chen, Kuang-Tsu Shih

Patent number: 6821896Abstract: A method is provided for forming contact/via hole openings without the detrimental volcano effect that is normally encountered in forming damascene structures. It is disclosed that the hole openings are needed to be filled with a protective material, in the first place, so as to prevent any damage to the exposed surface at the bottom of the openings. However, the filling material must be chosen properly, for otherwise, the material can leave behind a scum-like residue which then can erupt like a volcano during the subsequent process steps, which in turn can lead to functionality as well as reliability problems. It is disclosed in the present invention that when i-line photoresist (i-line PR), or, spin-on organic oxide is used as the protective filler material, the volcano effect can be avoided, and a Cu dual damascene interconnect with low RC delay characteristics can be obtained.Type: GrantFiled: May 31, 2001Date of Patent: November 23, 2004Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventor: Tsu Shih

Patent number: 6787470Abstract: A sacrificial semiconductor feature for preventing corrosion that can result during chemical-mechanical planarization (CMP) is disclosed. A semiconductor device of the invention is fabricated at least in part by performing CMP. The device includes a desired semiconductor feature and a sacrificial semiconductor feature. The desired semiconductor feature may have an unbalanced geometric pattern that includes a metallic line ending in at least one tip. The at least one tip is susceptible to corrosion resulting from performing CMP. The sacrificial semiconductor feature is preferably located off the metallic line of the desired semiconductor feature. The sacrificial semiconductor feature attracts charge induced during CMP that is otherwise attracted by the at least one tip of the desired semiconductor feature. The presence of the sacrificial semiconductor feature thus substantially prevents corrosion of the desired semiconductor feature, including its tip(s).Type: GrantFiled: May 17, 2002Date of Patent: September 7, 2004Assignee: Taiwan Semiconductor Manufacturing Co., LtdInventors: Chu-Wei Hu, Tsu Shih, Chen Cheng Chou
