SOLID IMAGE PICKUP DEVICE HAVING MICROLENSES |
摘要 |
In a solid image pickup device wherein a plurality of microlenses (28) are provided on a substrate (12) having light receiving portions (14), in opposition to the light receiving portions (14) so that incident light can converge onto the light receiving portions (14), the microlenses (28) are covered with a transparent resin layer (44) having a refractive index smaller than that of the microlenses (28). Therefore, the solid image pickup device (60), even when packaged in a molded body (72) made of a resin having a refractive index similar to that of the microlenses, can offer a good sensitivity because the microlenses (28) can effectively operate as condenser lenses due to the resin layer (44) between the molded body (72) and the microlenses (28). <IMAGE> |
