Abstract: PURPOSE: A method of programming a non-volatile memory device having a shared bit line structure prevents the program disturbance of a memory cell included in an unselected cell string by sufficiently boosting a voltage of a channel of the unselected cell string. CONSTITUTION: A first channel of a first cell string and a second channel of a second cell string are pre-charged by applying a first voltage to a bit line (S110). One cell string among the first cell string and the second cell string is selected (S130). A memory cell included in a selected cell string is programmed by applying a second voltage, which is lower than the first voltage and higher than the ground voltage, to the bit line.

Abstract: 본 발명은 활성 영역의 평면에 대하여 수직 방향으로 광을 방출시키기 위한 공진 공동 구조(resonant cavity structure)를 갖는 반도체 광 방출 장치 및 그 제조 방법에 관한 것이다.
본 발명은 공진된 광이 방출되어질 상부 전극의 윈도우 및 산화층의 전류 애퍼추어를 갖는 포스트에 있어서, 그들의 축이 자동으로 일치되도록 상기 전극을 자기 정렬로 에칭하여 상기 포스트를 형성한다. 상기 에칭시에 포스트 내에 적층된 예비 산화층의 측벽이 노출되며, 산화 공정에 의해 상기 예비 산화층의 측벽에서부터 수평으로 소정 칫수만큼 산화가 진행된다. 이러한 산화 공정에 의해 산화된 산화층은 고저항부가 되며, 산화되지 않은 부분은 전류 또는 광이 통과하게 되는 전류 애퍼추어가 된다. 이와 같이, 포스트는 전극에 의해 자기 정렬로 형성되고, 이 포스트의 노출된 측벽의 산화 처리에 의해 전류 애퍼추어가 형성되기 때문에 전극의 윈도우와 전류 애퍼추어의 축 정렬은 자동으로 이루어지게 된다. 그러므로, 전극 윈도우와 전류 애퍼추어의 정확한 축정렬에 의해 VCSEL의 전기 광학적 특성이 향상된다.
