摘要: Backthinning in an area selective manner is applied to imaging sensors 12 for use in electron bombarded devices. A further arrangement results in an array of collimators 51 aligned with pixels 42 or groups of pixels providing improved image contrast of such image sensor. Provision of a thin P-doped layer 52 on the illuminated rear surface provides both a diffusion barrier resulting in improved resolution and a functional shield for reference pixels. A gradient in concentration of P-doped layer 52 optimizes electron collection at the pixel array.

摘要: Backthinning in an area selective manner is applied to CMOS imaging sensors 12 for use in electron bombarded active pixel array devices. A further arrangement results in an array of collimators 51 aligned with pixels 42 or groups of pixels of an active pixel array providing improved image contrast of such image sensor. Provision of a thin P-doped layer 52 on the illuminated rear surface provides both a diffusion barrier resulting in improved resolution and a functional shield for reference pixels. A gradient in concentration of P-doped layer 52 optimizes electron collection at the pixel array.

摘要: A structure and method of manufacture is disclosed for a backside thinned imager that incorporates a conformal, Al2O3, low thermal budget, surface passivation. This passivation approach facilitates fabrication of backside thinned, backside illuminated, silicon image sensors with thick silicon absorber layer patterned with vertical trenches that are formed by etching the exposed back surface of a backside-thinned image sensor to control photo-carrier diffusion and optical crosstalk. A method of manufacture employing conformal, Al2O3, surface passivation approach is shown to provide high quantum efficiency and low dark current while meeting the thermal budget constraints of a finished standard foundry-produced CMOS imager.
