Title: Process for preparing contact window in the semiconductor device and its structure
Inventor: ZHANG YOU-ZHI
IPC: H01L21/768
Filed: 1997-04-14
Granted: 1999-12-01
Abstract: A semiconductor process, in particular a process for the contact window between two conductive layers having different planes (an upper conductive layer and a lower conductive layer); the key step is to form a recess beneath the contact window of two conductive layers in advance, which can be disposed in the insulating layer below the lower conductive layer; in subsequent formation of lower conductive layer, the concave region created by said recess can be filled. As such, the lower conductive layer has greater thickness at the designated position of contact window than at other regions. Thus after an insulating layer has been formed between upper and lower conductive layers, and etching of contact window is carried out, the bottom of contact window will not extend beyond lower conductive layer even if the depth of etching exceeds the thickness of said insulating layer, given the sufficient thickness of the second conductive layer. Therefore, the contact area between upper and lower conductive layers increases, which helps reduce the contact resistance between the two layers.
