Publication number: 20230154805Abstract: A method for stacking multi-layer wafers, and a system for stacking multi-layer wafers. The method includes bonding a wafer to a carrier wafer; a first feature pattern being defined in the wafer; acquiring overlay deviation values of different positions of the first feature pattern relative to the carrier wafer; fitting the overlay deviation values corresponding to the different positions and obtaining an actual deviation value of the wafer; and compensating an exposure process of the wafer based on the actual deviation value. In this way, an occurrence of the wafer failing to be exposed and being scrapped due to an alignment accuracy between the wafer and the carrier wafer being lower may be reduced.Type: ApplicationFiled: January 17, 2023Publication date: May 18, 2023Inventors: YICHENG FENG, YUHENG HUANG, BANG CHEN, SHENGJIN SONG

Patent number: 9848339Abstract: Methods, systems, and devices are disclosed for providing services, such as voice services, within flexible bandwidth systems. In general, the scaling of one or more aspects of a flexible bandwidth system may be compensated for through altering one or more aspects within a code domain. The tools and techniques may include scaling spreading factors (with rate matching tuning in some embodiments), multi-code transmission, code rate increases, AMR codec rate adjustments, and/or higher order modulation. Subframe decoding approaches for the reception scheme may also be utilized. These tools and techniques can be flexibly implemented on the mobile device and/or base station side. Some embodiments may also minimize the latency introduced by the transmission and/or reception process. Flexible bandwidths systems may utilize portions of spectrum that may be too big or too small to fit a normal bandwidth waveform.Type: GrantFiled: June 12, 2012Date of Patent: December 19, 2017Assignee: QUALCOMM IncorporatedInventors: Yuheng Huang, Bongyong Song, Edwin C.

Patent number: 9198219Abstract: Methods, devices, and instructions stored in non-transitory computer-readable medium are provided for adaptively adjusting when a mobile device requests fast dormancy (FD) by determining when applications executing on the mobile device stop using a connection to a cellular telecommunications network. An adaptive fast dormancy controller function executing on a processor of the mobile device monitors network traffic activity by the applications. The adaptive fast dormancy controller function may determine that an open network connection should be released using a device traffic inactivity timer that times durations of network inactivity by applications. The duration of the device traffic inactivity timer may be adjusted based upon observed application and/or network conditions. Multiple device traffic inactivity timers may be used to enable timing traffic inactivity of each application or groups of applications executing on the mobile device.Type: GrantFiled: September 6, 2012Date of Patent: November 24, 2015Assignee: QUALCOMM IncorporatedInventors: Yuheng Huang, Bongyong Song, Samir Salib Soliman

Patent number: 9001679Abstract: Methods, systems, and devices for supporting voice communications in a wireless communications system are provided. Some embodiments utilize multiple code channels to transmit the voice frames. These embodiments include parallel multi-code embodiments, offset multi-code embodiments, and multi-user multi-code embodiments.

Some embodiments transmit and receive a subset of subframes of voice frames received over flexible bandwidth code channels. In some embodiments, a subset of subframes based on a flexible bandwidth scaling factor of one or more flexible bandwidth code channels is transmitted. The receiver may decode the voice frame based on the received subset of subframes. An outer loop power control set-point may be adjusted to provide a predetermined frame error rate based on the number of transmitted subframes.Type: GrantFiled: June 7, 2012Date of Patent: April 7, 2015Assignee: QUALCOMM IncorporatedInventors: Soumya Das, Ozgur Dural, Edwin C.

Publication number: 20140226571Abstract: Apparatus and methods are disclosed for dynamically allocating an available bandwidth among different applications running at an access terminal operating in a wireless communication system that may be subject to certain bandwidth constraints. In particular, management of the allocation of resources when such resources are determined to be constrained may be implemented at the access terminal itself, for example, by reducing a requested bandwidth corresponding to at least one application flow from among a plurality of application flows. In this way, the superior information available to the access terminal regarding the demands and capabilities of the individual applications can be taken into account. Thus, multiple concurrently running applications competing for common limited resources may achieve a satisfactory level of service or QoS, resulting in an enhanced user experience.Type: ApplicationFiled: February 13, 2013Publication date: August 14, 2014Applicant: QUALCOMM IncorporatedInventors: Soumya DAS, Bongyong SONG, Yuheng HUANG

Publication number: 20130235956Abstract: In wireless communication systems, received signal estimation and detection is computationally intensive. During such processing, received signal matrices may be conditioned prior to inversion to improve stability. In particular, code domain conditioning, followed by time domain conditioning prior to inversion results in improved receiver performance. Such code and time domain conditioning may be particularly suited to a Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) system where code values are not averaged out of a received signal matrix.Type: ApplicationFiled: July 3, 2012Publication date: September 12, 2013Applicant: QUAL COMM IncorporatedInventors: Qiang Shen, Fuyun Ling, Aamod Dinkar Khandekar, Sequei Anatolievich Glazko, Insung Kang, Ming Kang, Dario Fertonani, Yuheng Huang
