Patent ID: 8722449

Claim:
A manufacturing method of a semiconductor device comprising the steps of: (a) providing a wiring substrate having an upper surface and a lower surface opposite to the upper surface; (b) mounting a sensor chip having a first major surface, a sensor region formed on the first major surface, a plurality of pixels formed in the sensor region, and a first rear surface opposite to the first major surface, on the upper surface of the wiring substrate so that the first rear surface faces to the upper surface of the wiring substrate; (c) disposing a first adhesive having a first viscosity at a plurality of positions on the first major surface of the sensor chip; (d) after the (c) step, forming a plurality of first spacers having a second viscosity higher than the first viscosity and also having adherence on the first major surface of the sensor chip by curing the first adhesive; (e) after the (d) step, disposing a second adhesive in a paste state on the first major surface of the sensor chip; (f) after the (e) step, disposing a first optical component having a light blocking layer in which a plurality of optical regions is formed, over the first major surface of the sensor chip via the first spacers and the second adhesive; and (g) after the (f) step, curing the second adhesive, wherein the (f) step disposes the first optical component over the first major surface of the sensor chip while applying a load to the first optical component, the (g) step cures the second adhesive in a state of not applying a load to the first optical component, the (f) step disposes the first optical component on the first major surface of the sensor chip via the first spacers and the second adhesive so that the optical regions overlap the pixels, and the optical region is a region where an opening portion is formed in the light blocking layer.
