摘要:
A ceramic green sheet is obtained by forming a ceramic coating containing at least a ceramic raw material powder, a binder, and an organic solvent in a sheet shape, followed by drying. The binder contains two or more kinds of polyvinyl acetal with different average degrees of polymerization, and polyvinyl acetal with a higher average degree of polymerization contains a relatively large amount of hydroxyl group, and polyvinyl acetal with a lower average degree of polymerization contains a relatively small amount of hydroxyl group. This green sheet is subjected to binder-removal and firing, thereby obtaining a ceramic capacitor in which inner electrode layers 2 and dielectric layers 1 are laminated alternately and external electrodes 3 are sintered at both ends of the laminate. Consequently, a decrease in the sheet strength caused by a reduction in the thickness of the dielectric layers is suppressed, and there are provided a high-strength green sheet, a laminated ceramic article, and a method for manufacturing the same.
摘要:
Provided is a solid-state image pickup device capable of suppressing deterioration of characteristic caused due to an antireflection film itself absorbing a light. In the solid-state image pickup device of the present invention, a plurality of color filters 8a, 8b, and 8c having spectral characteristics, respectively, different from each other are provided so as to correspond to a plurality of light reception sections 2, respectively, aligned on a semiconductor substrate 1. Further, a plurality of microlenses 10 are provided above the plurality of color filters 8a, 8b, and 8c, respectively. A plurality of antireflection films 11a are selectively formed on surfaces of the microlenses 10 provided above color filters 8b each having a predetermined spectral characteristic.
