    摘要: A method for reducing interfacial layer (IL) thickness for high-k dielectrics and metal gate stack is provided. In one embodiment, the method includes forming an interfacial layer on a semiconductor substrate, etching back the interfacial layer, depositing a high-k dielectric material over the interfacial layer, and forming a metal gate over the high-k dielectric material. The IL can be chemical oxide, ozonated oxide, thermal oxide, or formed by ultraviolet ozone (UVO) oxidation process from chemical oxide, etc. The etching back of IL can be performed by a Diluted HF (DHF) process, a vapor HF process, or any other suitable process. The method can further include performing UV curing or low thermal budget annealing on the interfacial layer before depositing the high-k dielectric material.

    摘要: In a cyclic code decoding method, a decoder analyzes a received codeword to identify unreliable symbols in the codeword, and sets candidate syndrome patterns accordingly. Then, a syndrome calculator calculates evaluated syndrome values associated with one of the candidate syndrome patterns, and an error location polynomial (ELP) generator generates an ELP according to the syndrome values. An error correction device corrects the errors in the codeword according to the ELP when a degree of the ELP is not more than a threshold value, and the syndrome calculator adjusts the syndrome values and the ELP generator generates another ELP according to the adjusted syndrome values when otherwise.

In communication systems, the invention proposes a crystal-less scheme in the device for wireless or wired-line communications. The operation concepts are that the transmitter Device-1 provides Device-2 a reference signal, and Device-2 takes this signal to generate a local signal with the similar frequency that has limited frequency error compared with the one from Device-1. This invention is done via the circuit-design methodology, so it can be implemented from any kinds of circuit implementation processes, especially the CMOS process. As a result, the hardware can be designed in the way of highly integration and extremely low cost.

    摘要: This invention provides the unique and high-throughput architecture for multiple video standards. Particularly, we propose a novel scheme to integrate the standard in-loop filter and the informative post-loop filter. Due to the non-standardization of post filter, it provides high freedom to develop a certain suitable algorithm for the integration with loop-filter. We modify the post filter algorithm to make a compromise between hardware integration complexity and performance loss. Further, we propose a hybrid scheduling to reduce the processing cycles and improve the system throughput. The main idea is that we use four pixel buffers to keep the intermediate pixel value and perform the horizontal and vertical filtering process in one hybrid scheduling flow. In our approach, we reduce processing cycles, and the synthesized gate counts are very small. Meanwhile, the synthesized results also indicate lower cost for hardware.
