Patent ID: 8796798

Claim:
An imaging module comprising: an imaging chip including a micro-lens configured to guide incident light and an imaging element provided in a semiconductor substrate and configured to convert the incident light guided by the micro-lens into an electric signal; and a polarizing glass chip including a polarizing filter glass having a polarizer configured to determine a polarization direction of the incident light and a transparent substrate, the polarizer being arranged on a surface of the transparent substrate such that the polarizer faces the micro-lens of the imaging chip, and a spacer member connected to the polarizing filter glass having the polarizer and configured to adjust a gap between the polarizer and the micro-lens of the imaging chip, wherein a melt-bonding surface of the spacer member is melt-bonded to a surface of the semiconductor substrate such that the polarizer of the polarizing glass chip and the micro-lens of the imaging chip are arranged close to each other via the gap, and such that the imaging element and the micro-lens of the imaging chip are sealed by the polarizing glass chip without degrading properties of received light, the spacer member includes a frame structure configured to enclose an outer periphery of the polarizer, the spacer member including the frame structure partially includes a cut portion, and the cut portion is configured to communicate spatially between a light-receiving region of the imaging chip and outside of the light-receiving region such that outgassing is achieved via the cut portion.
