Abstract:
A method for fabricating an image sensor comprises forming an over coat layer on an upper face of a semiconductor substrate on which a color filter layer is formed, forming a microlens on the over coat layer; covering the microlens with a protection layer, back grinding a lower face of the semiconductor substrate, and removing the protection layer of the microlens. In this method, the protection layer is formed on the microlens of an image sensor and is subsequently removed after back grinding.

A cell adhesive material with excellent cell adhesion and cell proliferating property and a method for producing the same are provided. The adhesion and proliferation of cells can be improved remarkably by the surface modification of a cell adhesive material comprising a polymer material containing carbon as a constituting element, such as polystyrene or segmented polyurethane, wherein at least a part of the surface is modified by ion bombardment through ion implantation. The method for producing such cell adhesive material comprises implanting ions into at least a part of the surface of the polymer material. The cell adhesive material and the method for producing the same are promising for application to cell culture petri dishes and hybrid-type medicinal materials.
