Claim:
1. A semiconductor device comprising: a multilayer substrate including an optical element; a light-transmitting plate provided on the substrate to cover the optical element, wherein a light incident surface of the light-transmitting plate in at least a portion covering the optical element is planar; and a lens of an inorganic material provided between the substrate and the light-transmitting plate, wherein the lens is provided in at least an effective photosensitive region of the device, wherein a structure having a same strength as a strength per unit area of the lens is provided at a portion in an effective photosensitive region-surrounding region, wherein the structure is formed from the inorganic material used to form the lens, wherein the structure has one of a first thickness and a lens shape in a first effective photosensitive region-surrounding region portion, wherein the structure has a second thickness in a second effective photosensitive region-surrounding portion, wherein the first photosensitive region-surrounding region portion is between the effective photosensitive region and the second photosensitive region-surrounding region portion, wherein the one of the first thickness and a maximum thickness of the lens shape is greater than the second thickness, and wherein the structure is provided as a flat film in at least the second effective photosensitive region-surrounding portion.
