摘要： A structure (and method for forming the same) for an image sensor cell. The method includes providing a semiconductor substrate. Then, a charge collection well is formed in the semiconductor substrate, the charge collection well comprising dopants of a first doping polarity. Next, a surface pinning layer is formed in the charge collection well, the surface pinning layer comprising dopants of a second doping polarity opposite to the first doping polarity. Then, an electrically conductive push electrode is formed in direct physical contact with the surface pinning layer but not in direct physical contact with the charge collection well. Then, a transfer transistor is formed on the semiconductor substrate. The transfer transistor includes first and second source/drain regions and a channel region. The first and second source/drain regions comprise dopants of the first doping polarity. The first source/drain region is in direct physical contact with the charge collection well.

摘要： A pixel for an image sensor includes a photosensor located within a substrate. A patterned dielectric layer having an aperture registered with the photosensor is located over the substrate. A lens structure is located over the dielectric layer and also registered with the photosensor. A liner layer is located contiguously upon a top surface of the dielectric layer, and the sidewalls and bottom of the aperture. The liner layer provides for enhanced reflection for off-axis incoming light and enhanced capture thereof by the photosensor. When the aperture does not provide a dielectric layer border for a metallization layer embedded within the dielectric layer, an exposed edge of the metallization layer may be chamfered.

摘要： The present invention relates to a design structure for a pixel sensor cell. The pixel sensor cell approximately doubles the available signal for a given quanta of light. A design structure for a pixel sensor cell having reduced complexity includes an n-type collection well region formed beneath a surface of a substrate for collecting electrons generated by electromagnetic radiation impinging on the pixel sensor cell and a p-type collection well region formed beneath the surface of the substrate for collecting holes generated by the impinging photons. A circuit structure having a first input is coupled to the n-type collection well region and a second input is coupled to the p-type collection well region, wherein an output signal of the pixel sensor cell is the magnitude of the difference of a signal of the first input and a signal of the second input.

摘要： A novel CMOS image sensor cell structure and method of manufacture. The imaging sensor comprises a substrate having an upper surface, a gate comprising a dielectric layer formed on the substrate and a gate conductor formed on the gate dielectric layer, a collection well layer of a first conductivity type formed below a surface of the substrate adjacent a first side of the gate conductor, a pinning layer of a second conductivity type formed atop the collection well at the substrate surface, and a diffusion region of a first conductivity type formed adjacent a second side of the gate conductor, the gate conductor forming a channel region between the collection well layer and the diffusion region. A portion of the bottom of the gate conductor is recessed below the surface of the substrate. Preferably, a portion of the gate conductor is recessed at or below a bottom surface of the pinning layer to a depth such that the collection well intersects the channel region thereby eliminating any potential barrier interference caused by the pinning layer.
