Abstract: A programmable analog-to-digital converter (ADC) for use in a CMOS imaging system, the CMOS imaging system having an array of pixels, and the ADC configured to provide a enhanced conversion resolution for pixels providing a low analog voltage level and a relatively coarser conversion resolution for pixels providing a relatively higher analog voltage level.

Abstract: This invention discloses a method of forming an electrode of semiconductor device. In the present invention, an amorphous silicon film is formed on a substrate, and silicon seeds are formed on the silicon film. Thereinafter, the heat treatment is performed for growing, thereby forming an hemispherical roughness structure on surface of said charge storage electrode and increasing a surface area in unit area.

Abstract: This invention relates to a method for forming a stacked capacitor in a semiconductor device. This invention can increase the capacitance of a capacitor by planarizing a polysilicon layer for a charge storage electrode and forming a recess on the planarized polysilicon layer.
