titleOfInvention | Contact hole formation method of semiconductor device |
abstract | The present invention relates to a method for forming a contact hole in a semiconductor device, and in manufacturing a device in which a super-contact hole serving as a pad and a normal-contact hole serving as a general wiring connection exist simultaneously in a packaging process, Is formed first, and the wafer is slowly rotated up, down, left and right, and the super-contact hole is filled with BARC, and the photoresist pattern for the normal-contact hole is formed on the entire structure including the super-contact hole filled with BARC, followed by the etching process. Since a contact hole is formed and a photoresist removal process is performed thereafter, two types of contact holes can be easily formed on one wafer without an additional process such as a planarization process due to poor coating in the super-contact hole. . n n n n Super contact hole, normal contact hole, packaging, up, down, left and right |
