    Abstract: 본 발명은 T형 게이트 전극의 형성방법에 관한 것으로서, 반도체 기판 상의 소정 부분에 미세 게이트 금속을 형성하고, 반도체 기판 및 미세 게이트 금속상에 절연막과 평탄화막을 형성한 후 절연막이 노출되도록 평탄화막을 에치백하고, 절연막의 노출된 부분을 등방성으로 식각하여 평탄화막의 역경사를 이루는 측면을 노출시키고 저저항금속을 방향성을 갖도록 증착한다. 따라서, 광학적 기소그라피 공정으로 쉽게 T-형상의 게이트를 형성할 수 있으므로 생산성을 향상시킬 수 있으며, 미세 게이트 패턴 상에 중첩되는 저저항금속을 자기 정렬되게 형성할 수 있다.

    Abstract: PURPOSE: An electric optical polymer for a wavelength division multiplexing optical communication network, a high speed tunable selecting filter using multi-grating and their operating method are provided to enable implementation of a dense wavelength division multiplexing based optical communication and be used for an optical information storing device technique utilizing an optical refraction. CONSTITUTION: An optical waveguide(103) collects a plurality of lights made incident to a single mode. A Bragg grating unit passes only a light of a desired wavelength among the plurality of lights made incident along the optical waveguide(103) and reflects the remaining lights along the optical waveguide(103) to emit them externally. A proceeding waveform electrode(105) changes a region of a Bragg grating reflection wave by an electro-optical effect and transmits or reflects a specific wavelength selectively. A TEC(106) tunes the wavelength of the whole bragg reflection wave by using a heat optical effect of a polymer.
