    摘要: Provided is a method of forming and/or using a backside-illuminated sensor including a semiconductor substrate having a front surface and a back surface. A transfer transistor and a photodetector are formed on the front surface. The gate of the transfer transistor includes an optically reflective layer. The gate of the transfer transistor, including the optically reflective layer, overlies the photodetector. Radiation incident the back surface and tratversing the photodetector may be reflected by the optically reflective layer. The reflected radiation may be sensed by the photodetector.

    摘要: Provided is a method for fabricating an image sensor device that includes providing a substrate having a front side and a back side; patterning a photoresist on the front side of the substrate to define an opening having a first width, the photoresist having a first thickness correlated to the first width; performing an implantation process through the opening using an implantation energy correlated to the first thickness thereby forming a first doped isolation feature; forming a light sensing feature adjacent to the first doped isolation feature, the light sensing feature having a second width; and thinning the substrate from the back side so that the substrate has a second thickness that does not exceed twice a depth of the first doped isolation feature. A pixel size is substantially equal to the first and second widths.

    摘要: Provided are a semiconductor device and a method for its manufacture. In one example, the method includes forming an isolation structure having a first refraction index over a sensor embedded in a substrate. A first layer having a second refraction index that is different from the first refraction index is formed over the isolation structure. The first layer is removed from at least a portion of the isolation structure. A second layer having a third refraction index is formed over the isolation structure after the first layer is removed. The third refraction index is substantially similar to the first refraction index.
