Proximity Gettering Design of Hydrocarbon–Molecular–Ion–Implanted Silicon Wafers Using Dark Current Spectroscopy for CMOS Image Sensors

Sensors, 2019
We developed silicon epitaxial wafers with high gettering capability by using hydrocarbon−molecular−ion implantation. These wafers also have the effect of hydrogen passivation on process-induced defects and a barrier to out-diffusion of ...

Mapping of QTL affecting incidence of blood and meat inclusions in egg layers

BMC Genetics, 2011
Background Occurrence of blood and meat inclusions is an internal egg quality defect. Mass candling reveals most of the spots, but because brown eggshell hampers selection in brown chicken lines it has not been possible to eliminate the defect by ...

Proximity gettering technique using CH ₃ O multielement molecular ion implantation for the reduction of the white spot defect density in CMOS image sensor

Japanese Journal of Applied Physics, 2019
Abstract We have characterized CH 3 O ion-implanted epitaxial wafers in device fabrication processes. We confirmed that the CH 3 O ion-implanted wafers can reduce the density of white spot defects in CMOS image sensors.
