Publication number: 20240085803Abstract: Photolithography overlay errors are a source of patterning defects, which contribute to low wafer yield. An interconnect formation process that employs a patterning photolithography/etch process with self-aligned interconnects is disclosed herein. The interconnection formation process, among other things, improves a photolithography overlay (OVL) margin since alignment is accomplished on a wider pattern. In addition, the patterning photolithography/etch process supports multi-metal gap fill and low-k dielectric formation with voids.Type: ApplicationFiled: November 20, 2023Publication date: March 14, 2024Applicant: Taiwan Semiconductor Manufacturing Co., Ltd.Inventors: Tai-I Yang, Wei-Chen Chu, Hsiang-Wei Liu, Shau-Lin Shue, Li-Lin Su, Yung-Hsu Wu

Publication number: 20170316610Abstract: Assembly instruction system includes at least one depth camera, database, processor, and display. Depth camera captures first object image. Database stores multiple known object images and assembly tree. Processor compares first object image with known object images separately to recognize first object corresponding to first object image and a three-dimensional position and orientation of first object, and obtains second object (or some other multiple objects) corresponding to first object according to captured image and assembly tree. Processor generates at least one virtual arrow according to three-dimensional position and orientation. Display displays augmented reality image having at least one virtual arrow added on first object image and second object (or some other multiple objects) image(s). Virtual arrow indicates a moving direction for assembling first object and second object (or some other multiple objects). The above process is repeatedly performed until the whole device is assembled.Type: ApplicationFiled: July 11, 2016Publication date: November 2, 2017Inventors: I-Chen LIN, Li-Chen WU, Ming-Han TSAI, Jen-Hui CHUANG

Patent number: 7461801Abstract: A multi-functional food processor contains a machine body and a top cover. It further includes a container and a driving device. The drive shaft of the driving device is extended to the container, and a juicer shredder, a vegetable shredder or a meat grinder blade is selectively installed in the transmission shaft, which is connected to the drive shaft. The top cover is provided with two feed tubes, where the first feed tube is used for feeding vegetables and fruits in conjunction with a first pusher. The second feed tube is used for feeding vegetables or meat into a vegetable shredder or a meat grinder blade in conjunction with push of the second pusher. A safety switch is mounted between the feed tubes, and it allows only one pusher to operate in each sole feed tube thus avoiding the food being fed into the wrong feed tube.Type: GrantFiled: January 5, 2007Date of Patent: December 9, 2008Assignee: Lyu Jan Co., Ltd.Inventor: Li-Chen Wu Chang

Publication number: 20080185467Abstract: A food processor having gear-shifting function includes a machine body, gear-shifting and non-gear-shifting cutting assemblies. Each of the cutting assemblies includes a fixed seat and a rotating seat. The rotating seat is assembled onto the fixed seat via a shaft and a bearing, so that the rotating seat is able to freely rotate relatively to the fixed seat. The non-gear-shifting cutting assembly is not mounted with the gear-shifting mechanism; therefore, when the cutting assembly is installed on the drive shaft of the motor, the cutting assembly is to output at the same speed as that of the motor. The gear-shifting cutting assembly is disposed with a gear-shifting mechanism in the fixed seat. Therefore, when the drive shaft of the motor rotates, the shaft is to rotate by the gear-shifting output via the gear-shifting mechanism, which makes the blade mounted on the rotating seat to rotate at a gear-shifted speed.Type: ApplicationFiled: February 5, 2007Publication date: August 7, 2008Inventor: LI-CHEN WU CHANG
