Abstract
An integrated circuit device structure which avoids misalignment when a contact hole is formed to expose a contact pad and a method of fabricating the same, are provided. The integrated circuit device includes a semiconductor substrate having a conductive region and an insulating region, a contact pad on the conductive region of the semiconductor substrate, an auxiliary pad adjacent to the contact pad, and an interlevel insulating layer on the semiconductor substrate and having a contact hole for exposing both the contact pad and the auxiliary pad.
