Abstract

본 발명은 액정표시소자 및 제조방법에 관한 것으로, 종래에는 게이트 전극을 양극 산화하여 게이트 절연막을 형성하므로 인해 게이트전극과 게이트 절연막 사이에 단차-현상이 발생하여 소자제조시 게이트전극이 단선되어 수율을 저하시키는 문제점이 있었다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid crystal display device and a manufacturing method. In the related art, a step difference phenomenon is generated between the gate electrode and the gate insulating film by anodizing the gate electrode, whereby the gate electrode is disconnected when the device is manufactured, resulting in high yield. There was a problem of deterioration.

본 발명은 상기와 같은 종래의 문제점을 감안하여 게이트전극 위에 금속층을 증착 후 양극산화 방법으로 산화하여 양극산화막을 제조하고 게이트전극을 광마스크를 사용하는 자기정합빔을 이용하여 정확한 패턴으로 식각한 후 게이트전극을 산화시켜 게이트 절연층을 형성하여 단차 현상을 방지하므로 소자제조시 단선을 줄일 수 있어 수율을 향상하는 효과가 있다.In view of the above-described problems, the present invention manufactures an anodized film by depositing a metal layer on a gate electrode and then oxidizes it by an anodizing method, and then etching the gate electrode into an accurate pattern using a self-aligned beam using an optical mask. Since the gate electrode is oxidized to form a gate insulating layer to prevent the step difference, disconnection can be reduced during device fabrication, thereby improving yield.
