    Abstract: Embodiments of mechanisms of a backside illuminated image sensor structure are provided. The backside illuminated image sensor structure includes a device substrate having a frontside and a backside and pixels formed at the frontside of the substrate. The backside illuminated image sensor structure further includes a metal element formed in a dielectric layer over the backside of the substrate and a color filter layer formed over the dielectric layer. In addition, the metal element is configured to form a light blocking area in the device substrate and is made of copper.

    Abstract: The present disclosure relates to a back-side illuminated CMOS image sensor (BSI CIS). In some embodiments, the BSI CSI has a semiconductor substrate with a front-side and a back-side. A plurality of photodetectors are located within the front-side of the semiconductor substrate. An implantation region is located within the semiconductor substrate at a position separated from the plurality of photodetectors. The implantation region is disposed below the plurality of photodetectors and has a non-uniform doping concentration along a lateral plane parallel to the back-side of the semiconductor substrate. The non-uniform doping concentration allows for the BSI CSI to achieve a small total thickness variation (TTV) between one or more photodetectors and a back-side of a thinned semiconductor substrate that provides for good device performance.

    Abstract: A metal-insulator-metal (MIM) capacitor includes a semiconductor substrate and a capacitor device. The capacitor device includes a first conductor upright on the semiconductor substrate, a second conductor upright on the semiconductor substrate, and an insulator disposed used for insulating the first conductor from the second conductor. In a method for fabricating the capacitor device, a mask including a test line pattern and a capacitor pattern with a first trench pattern and a second trench pattern is used to form a test line and the first conductor and the second conductor of the capacitor device, thereby decreasing the cost of for fabricating the MIM capacitor.

    Abstract: Formation methods of a semiconductor device structure are provided. A method includes forming a dielectric layer over a first conductive feature and a second conductive feature. The method also includes depositing a conformal layer in a first via hole and a second via hole in the dielectric layer. The method further includes removing the conformal layer in the second via hole. The dielectric layer remains covered by the conformal layer in the first via hole. In addition, the method includes etching the conformal layer in the first via hole and the dielectric layer until the first conductive feature and the second conductive feature become exposed through the first via hole and the second via hole, respectively. The method also includes forming a third conductive feature in the first via hole and a fourth conductive feature in the second via hole.
