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.

摘要： The present invention is CMOS image sensor and its method of fabrication. This invention provides an efficient structure to improve the quantum efficiency of a CMOS type photodiode with borderless contact. The image sensor comprises a N-well/P-substrate type photodiode with borderless contact and dielectric structure covering the photodiode region. The dielectric structure is located between the photodiode and the interlevel dielectric (ILD) and is used as a buffer layer for the borderless contact. The method of fabricating a high performance photodiode comprises forming a photodiode in the n-well region of a shallow trench, and embedding a dielectric material between the ILD oxide and the photodiode having a refraction index higher than the ILD oxide.

摘要： A semiconductor device including a semiconductor substrate having a photosensor formed therein; a first layer overlying the substrate, the first layer includes a portion having a generally concave shaped surface being the negative shaped of a micro-lens to be formed there over; a second layer overlying the first layer, the second layer including a generally convex shaped portion vertically aligned with and mating with the generally concave shaped surface, the generally convex shaped portion being constructed and arranged to define a micro-lens positioned to cause parallel light passing through the micro-lens to converge on and strike the photosensor.
