Provided is a three-dimensional integrated circuit (3DIC) structure including a first die and a second die bonded together by a hybrid bonding structure. One of the first die and the second die has a pad and a cap layer disposed over the pad. The cap layer exposes a portion of a top surface of the pad, and the portion of the top surface of the pad has a probe mark. A bonding metal layer of the hybrid bonding structure penetrates the cap layer to electrically connect to the pad. A method of fabricating the first die or the second die of 3DIC structure is also provided. |
