    摘要： A new method to form CMOS image sensors in the manufacture of an integrated circuit device is achieved. The method comprises providing a semiconductor substrate. Sensor diodes are formed in the semiconductor substrate each comprising a first terminal and a second terminal. Gates are formed for transistors in the CMOS image sensors. The gates comprise a conductor layer overlying the semiconductor substrate with an insulating layer therebetween. The transistors include reset transistors. Ions are implanted into the semiconductor substrate to form source/drain regions for the transistors. The source regions of the reset transistors are formed in the first terminals of the sensor diodes. Ions are implanted into the reset transistor sources to form double diffused sources. The implanting is blocked from other source/drain regions.

    摘要： An optical image sensor is fabricated by forming a pixel array and a peripheral region surrounding the pixel array on a semiconductor substrate, the peripheral region containing peripheral circuitry. An inter-level-dielectric layer is formed over the substrate and a plurality of interconnect wiring layers are formed over the inter-level-dielectric layer. Each interconnect wiring layer includes interconnecting metal features and a layer of inter-level-dielectric material covering the interconnecting metal features. The plurality of interconnect wiring layers are provided in a manner that there are N levels of wiring layers in the peripheral region and 1 to (N−1) levels of wiring layers over the pixel array. An etch-stop layer is formed over the top-most level interconnecting metal features in the peripheral region.

    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 image sensor 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 new grid metal design for image sensors is disclosed which is comprised of a semiconductor image sensor chip having a pixel region covering most of the chip and a logic circuit region on the chip periphery. The pixel region contains, an array of image pixels where for each image pixel the majority of its area is occupied by a light sensing element and the other image pixel circuit elements are arranged in the periphery of the image pixel without overlapping the image-sensing element. A number of metal levels are of the first type, at which functional metal patterns exist both for the chip peripheral logic circuits and for the pixel circuit elements. A number of metal levels are of the second type, at which functional metal patterns exist only for the chip peripheral logic circuits and dummy metal patterns cover the pixel region except for the light sensing elements. A first dielectric layer is disposed under the first metal layer, an interlevel dielectric layer between metal levels of either type and a passivation layer over the last metal level.

    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.
