Publication number: 20240118073Abstract: Manufacturing of a shoe is enhanced by creating 3-D models of shoe parts. For example, a laser beam may be projected onto a shoe-part surface, such that a projected laser line appears on the shoe part. An image of the projected laser line may be analyzed to determine coordinate information, which may be converted into geometric coordinate values usable to create a 3-D model of the shoe part. Once a 3-D model is known and is converted to a coordinate system recognized by shoe-manufacturing tools, certain manufacturing steps may be automated.Type: ApplicationFiled: December 8, 2023Publication date: April 11, 2024Inventors: Patrick C. Regan, Chih-Chi Chang, Kuo-Hung Lee, Ming-Feng Jean

Patent number: 11953877Abstract: Manufacturing of a shoe or a portion of a shoe is enhanced by executing various shoe-manufacturing processes in an automated fashion. For example, information describing a shoe part may be determined, such as an identification, an orientation, a color, a surface topography, an alignment, a size, etc. Based on the information describing the shoe part, automated shoe-manufacturing apparatuses may be instructed to apply various shoe-manufacturing processes to the shoe part, such as a pickup and placement of the shoe part with a pickup tool.Type: GrantFiled: October 20, 2022Date of Patent: April 9, 2024Assignee: NILE, Inc.Inventors: Dragan Jurkovic, Patrick Conall Regan, Chih-Chi Chang, Chang-chu Liao, Ming-Feng Jean, Kuo-Hung Lee, Yen-Hsi Liu, Hung-Yu Wu

Publication number: 20240113032Abstract: Interconnect structure packages (e.g., through silicon vias (TSV) packages, through interlayer via (TIV) packages) may be pre-manufactured as opposed to forming TIVs directly on a carrier substrate during a manufacturing process for a semiconductor die package at backend packaging facility. The interconnect structure packages may be placed onto a carrier substrate during manufacturing of a semiconductor device package, and a semiconductor die package may be placed on the carrier substrate adjacent to the interconnect structure packages. A molding compound layer may be formed around and in between the interconnect structure packages and the semiconductor die package.Type: ApplicationFiled: April 25, 2023Publication date: April 4, 2024Inventors: Kai-Fung CHANG, Chin-Wei LIANG, Sheng-Feng WENG, Ming-Yu YEN, Cheyu LIU, Hung-Chih CHEN, Yi-Yang LEI, Ching-Hua HSIEH

Patent number: 9437715Abstract: A manufacturing method of a non-volatile memory is provided. A tunneling dielectric layer, a first conductive pattern, and isolation structures are formed on a substrate. Using a first photoresist layer as a mask, the first conductive pattern is partially removed to form a first opening exposing the substrate. An insulating layer is formed to fill the first opening and cover the first conductive pattern and the isolation structures. Using a second photoresist layer shielding a portion of the first conductive pattern as a mask, the insulating layer surrounding the first conductive pattern is removed to form a patterned insulating layer having a second opening exposing a portion of the first conductive pattern. An inter-gate dielectric layer and a second conductive pattern are formed on the first conductive pattern to fill the second opening, the first conductive pattern forms a floating gate, and the second conductive pattern forms a control gate.Type: GrantFiled: April 28, 2015Date of Patent: September 6, 2016Assignee: Powerchip Technology CorporationInventors: Chih-Ping Chung, Ming-Yu Ho, Ming-Feng Chang, Hung-Kwei Liao
