Abstract: 본 발명은 박막 트랜지스터의 제작에 관한 것으로 일반적으로 사용되고 있는 박막 트랜지스터의 제조공정은 5가지의 패턴 즉, 게이트패턴, 활성층 패턴, 투명전극 패턴, 베리어금속 패턴, 드레인/소스전극 패턴을 형성하는 과정을 수반하며 상기의 패턴을 형성시킬때마다 마스크를 사용하여야 하므로 제조공정이 복잡해져서 제품의 수율이 저하되고 생산비가 많이 소요되는 문제점을 가지고 있었다. 
     따라서 본 발명은 상기와 같은 종래의 박막 트랜지스터 제조공정에 따른 결함을 감안하여, 본 발명은 게이트 패턴을 마스크 대용으로 이용하고 베리어 금속의 사용시 연속증착 및 연속 식각작업에 의해 베리어 금속막위에 감광막이 잔류하는 것을 방지함으로써 마스크수의 감소에 따른 제조공정의 단축, 생산수율향상 및 생산비의 절감효과를 창출할 뿐만 아니라 박막 트랜지스터의 특성을 양호하게 유지시킬 수 있는 효과를 제공한다.

Title: Narrowband Wireless Communications Cell Search
Inventor: ALBERTO RICO ALVARINO
Filed: 2018-08-22
Abstract: Methods, systems, and devices for wireless communication are described. A base station may broadcast a synchronization signal using a narrowband portion of a bandwidth of a cell. The synchronization signal may include a sequence repeated over several symbol periods using a cover code to support power-efficient cell acquisition. A user equipment (UE) receiving the synchronization signal may determine frequency and timing information for a cell by performing a weighted combination and accumulation of low complexity autocorrelation and cross-correlation procedures on the synchronization signal. The reduced complexity correlation procedures may be enabled based on the use of the cover code and a base sequence. In some cases, the cross-correlation may be performed at multiple sampling rates. The use of the cover code within the synchronization signal may also support correlation procedures that use recursive or repeated updates, which may allow for further reduced computational complexity r
