    摘要: A plurality of apertures is formed in at least one first insulating layer disposed over a sensor formed in a semiconductor substrate. A second insulating layer is disposed over the at least one first insulating layer and the plurality of apertures in the at least one first insulating layer. The apertures form hollow regions in the at least one first insulating layer over the sensor, allowing more light or energy to pass through the at least one first insulating layer to the sensor, and increasing the sensitivity of the sensor.

    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.
