具高能隙偏移層結構之薄膜場效電晶體元件
(2001-06-23)
張俊彥
一種具高能隙偏移層結構之薄膜場效電晶體元件，係在基底上的源極/汲極和閘極底下閘極絕緣層之間,垂直疊放複數個不同能隙之半導體層,該複數個半導體層包含高-低-高-低能隙,低-高-低能隙,高-低-高能隙或低-高能隙結構的半導體層,其中低能隙半導體層鄰接閘極絕緣層,作為載子的通道層，在元件導通時能傳導載子，而鄰接通道層的高能隙偏移層,能在該元件關閉狀態下，阻擋傳導載子發生能帶到能帶的穿透傳輸，降低閘極感應之汲極漏電流,另外,鄰接高能隙偏移層的低能隙半導體層，形成半導體與金屬層之間的歐姆接觸區,當做源極/汲極的接觸層,而鄰接閘極的高能隙介面層，則是用來捕捉可能存在於通道層與閘極絕緣層之間的介面缺陷,使元件特性便不會受閘極絕緣層20的介面特性直接影響，並讓該元件在導通狀態下能維持相當大的導通電流，同時在關閉狀態下,能大幅降低元件之關閉電流,提高其開/關電流比，適合應用到液晶顯示器上,可以大幅提升其畫面品質。

Method and apparatus for solving key equation polynomials in decoding error correction codes
(2003-07-03)
Chang, Hsie-Chia
;
Lee, Chen-Yi
The presently invention discloses a method for computing error locator polynomial and error evaluator polynomial in the key equation solving step of the error correction code decoding process whereby the polynomials are generated through at most t intermediate iterations that can be implemented with minimal amount of hardware circuitry. However, depending on the selected (N,K) code, the number of cycles required for the calculation of the polynomials would be within the time required for the calculation of upstream data. Additionally, the present invention for computing the error locator polynomial and the error value polynomial employs an efficient scheduling of a small number of registers and finite-field multipliers (FFMs) without the need of finite-field inverters (FFIs) is illustrated. Using these new methods, a new area-efficient architecture that uses only 4t+2ρ+4 registers and three FFMs and no FFIs is presented to implement the inversionless Euclidean algorithm.

The present invention proposes a fast motion estimation using N-queen pixel decimation, whereby after a reference block and a block to be processed are selected in a video sequence, an N×N queens pattern is used for pixel decimation to perform block match, thereby obtaining a good enough block difference value. The present invention combines pixel decimation with fast motion estimation for search points reduction to achieve the object of simplifying computational complexity of motion estimation. Therefore, the present invention can sieve out sufficiently representative pixels and will not increase extra computational complexity.

Based upon the Euclidean algorithm, it can be implemented with minimal hardware circuitry and provide a method and apparatus for solving key equation within a t-step iterative decoding procedure while the prior art architectures require at most 2t iterations. It is yet another object of the present invention to provide a method and apparatus for solving key equation polynomials without decreasing the overall decoding speed of the decoder. Briefly, in a presently invention, a method for computing error locator polynomial and error evaluator polynomial in the key equation solving step of the error correction code decoding process is presented whereby the polynomials are generated through at most t intermediate iterations that can be implemented with minimal amount of hardware circuitry. However, depending on the selected (N,K) code, the number of cycles required for the calculation of the polynomials would be within the time required for the calculation of upstream data. Additionally, a presently invention for computing the error locator polynomial and the error value polynomial employs an efficient scheduling of a small number of registers and finite-field multipliers (FFMs) without the need of finite-field inverters (FFIs) is illustrated. Using these new methods, a new area-efficient architecture that uses only 4t+2 ρ+4 registers and three FFMs and no FFIs is presented to implement the inversionless Euclidean algorithm. This method and architecture can be applied to a wide variety of RS and BCH codes with suitable code sizes.
