Patent ID: 8637911

Claim:
A method of fabricating the solid-state imaging device including a substrate, a dielectric layer on the substrate, and an array of pixels, each of the pixels comprising: a pixel electrode; an organic layer which is provided above the pixel electrode and comprises a photoelectric layer generating a charge in response to light received; a counter electrode which is provided above the organic layer and is common to the pixels; a sealing layer covering the counter electrode; a color filter which is provided above the sealing layer; a readout circuit reading a signal corresponding to the charge collected by the pixel electrode; and a light-collecting unit for leading light transmitted through the color filter to the photoelectric layer of the pixel where the color filter is located, the photoelectric layer comprising an organic p-type semiconductor or and an organic n-type semiconductor, the organic layer further comprising a charge blocking layer between the photoelectric layer and at least one of the pixel electrode and the counter electrode to block charge injection from the at least one of the pixel electrode and the counter electrode to the photoelectric layer, an ionization potential of the charge blocking layer and an electron affinity of the organic n-type semiconductor present in the photoelectric layer having a difference of at least 1 eV, and a surface of the pixel electrodes under a side of the photoelectric layer and a surface of the dielectric layer under a side of the photoelectric layer being substantially coplanar, the method, comprising, in the following order: forming an array of pixel electrodes; forming a layer of a dielectric material providing the dielectric layer; and planarizing the dielectric material by chemical mechanical polishing or etch-back.
