Patent number: 12418384Abstract: The techniques described herein relate to methods, apparatus, and computer readable media configured to schedule individual orthogonal frequency-division multiple access (OFDMA) resources on an upstream channel to serve a data transmission request from a downstream device. A schedule for a set of available resources on the upstream channel to serve the data transmission request is generated, based on a dynamic bit loading profile, including generating data indicative of a first bit loading profile for a first set of resources from the set of available resources for a first burst, and data indicative of a second bit loading profile for a second set of resources from the set of available resources for a second burst. The schedule is transmitted to a downstream device, such that the downstream device is configured to encode the first burst using the first bit loading profile and the second burst using the second bit loading profile.Type: GrantFiled: April 17, 2024Date of Patent: September 16, 2025Assignee: ARRIS Enterprises LLCInventors: Hongbiao Zhang, Chain Lee, Yanbo Yuan, Tao Yu, Weidong Chen

Patent number: 10497567Abstract: Implementations described herein generally relate to an etching process for etching materials with high selectivity. In one implementation, a method of etching a gate material to form features in the gate material is provided. The method includes (a) exposing a cobalt mask layer to a fluorine-containing gas mixture in a first mode to form a passivation film on the cobalt mask layer. The cobalt mask layer exposes a portion of a gate material disposed on a substrate. The method further comprises (b) exposing the portion of the gate material to an etching gas mixture in a second mode to etch the portion of the gate material. The portion of the gate material is etched through openings defined in the cobalt mask layer and the portion of the gate material is etched at a greater rate than the cobalt mask layer having the passivation layer disposed thereon.Type: GrantFiled: July 16, 2018Date of Patent: December 3, 2019Assignee: APPLIED MATERIALS, INC.Inventors: Hailong Zhou, Yangchung Lee, Chain Lee, Hui Sun, Jonathan Sungehul Kim
