    Abstract: A method that forms a structure implants a well implant into a substrate, patterns a mask on the substrate (to have at least one opening that exposes a channel region of the substrate) and forms a conformal dielectric layer on the mask and to line the opening. The conformal dielectric layer covers the channel region of the substrate. The method also forms a conformal gate metal layer on the conformal dielectric layer, implants a compensating implant through the conformal gate metal layer and the conformal dielectric layer into the channel region of the substrate, and forms a gate conductor on the conformal gate metal layer. Additionally, the method removes the mask to leave a gate stack on the substrate, forms sidewall spacers on the gate stack, and then forms source/drain regions in the substrate partially below the sidewall spacers.

A first transfer gate device comprises a diodic or split transfer gate conductor structure having a first doped region of first conductivity type material and a second doped region of a second conductivity type material. A photosensing device is formed adjacent the first doped region for collecting charge carriers in response to light incident thereto, and, a diffusion region of a second conductivity type material is formed at or below the substrate surface adjacent the second doped region of the transfer gate device for receiving charges transferred from the photosensing device while preventing spillback of charges to the photosensing device upon timed voltage bias to the diodic or split transfer gate conductor structure. Alternately, an intermediate charge storage device and second transfer gate device may be provided which may first temporarily receive charge carriers from the photosensing device, and, upon activating the second transfer gate device in a further timed fashion, read out the charge stored at the intermediate charge storage device for transfer to the second transfer gate device while preventing spillback of charges to the photosensing device.

    Abstract: Disclosed is a transistor with a raised collector pedestal in reduced dimension for reduced base-collector junction capacitance. The raised collector pedestal is on the top surface of a substrate, extends vertically through dielectric layer(s), is un-doped or low-doped, is aligned above a sub-collector region contained within the substrate and is narrower than that sub-collector region. An intrinsic base layer is above the raised collector pedestal and the dielectric layer(s). An extrinsic base layer is above the intrinsic base layer. Thus, the space between the extrinsic base layer and the sub-collector region is increased. This increased space is filled by dielectric material and the electrical connection between the intrinsic base layer and the sub-collector region is provided by the relatively narrow, un-doped or low-doped, raised collector pedestal. Consequently, base-collector junction capacitance is reduced and, consequently, the maximum oscillation frequency is increased.

    Abstract: A method for manufacturing a pixel sensor cell that includes a photosensitive element having a non-laterally disposed charge collection region. The method includes forming a trench recess in a substrate of a first conductivity type material, and filling the trench recess with a material having second conductivity type material. The second conductivity type material is then diffused out of the filled trench material to the substrate region surrounding the trench to form the non-laterally disposed charge collection region. The filled trench material is removed to provide a trench recess, and the trench recess is filled with a material having a first conductivity type material. A surface implant layer is formed at either side of the trench having a first conductivity type material. A collection region of a trench-type photosensitive element is formed of the outdiffused second conductivity type material and is isolated from the substrate surface.

    Abstract: Protuberances, having vertical and lateral dimensions less than the wavelength range of lights detectable by a photodiode, are formed at an optical interface between two layers having different refractive indices. The protuberances may be formed by employing self-assembling block copolymers that form an array of sublithographic features of a first polymeric block component within a matrix of a second polymeric block component. The pattern of the polymeric block component is transferred into a first optical layer to form an array of nanoscale protuberances. Alternately, conventional lithography may be employed to form protuberances having dimensions less than the wavelength of light. A second optical layer is formed directly on the protuberances of the first optical layer. The interface between the first and second optical layers has a graded refractive index, and provides high transmission of light with little reflection.

    Abstract: A CMOS image sensor and method of fabrication wherein the sensor includes Copper (Cu) metallization levels allowing for incorporation of a thinner interlevel dielectric stack to result in a pixel array exhibiting increased light sensitivity. The CMOS image sensor includes structures having a minimum thickness of barrier layer metal that traverses the optical path of each pixel in the sensor array or, that have portions of barrier layer metal selectively removed from the optical paths of each pixel, thereby minimizing reflectance. That is, by implementing various block or single mask methodologies, portions of the barrier layer metal are completely removed at locations of the optical path for each pixel in the array. In a further embodiment, the barrier metal layer may be formed atop the Cu metallization by a self-aligned deposition.

    Abstract: A tensile-stress-generating structure is formed above a gate electrode in a CMOS image sensor to apply a normal tensile stress between a charge collection well of a photodiode, which is also a source region of a transfer transistor, and a floating drain in the direction connecting the source region and the floating drain. The tensile stress lowers the potential barrier between the source region and the body of the transfer transistor to effect a faster and more through transfer of the electrical charges in the source region to the floating drain. Image lag is thus reduced in the CMOS image sensor. Further, charge capacity of the source region is also enhanced due to the normal tensile stress applied to the source region.
