Claim:
1. A thin biometric detection module configured to detect at least one biometric characteristic of a part of human body, the thin biometric detection module comprising: a substrate having a substrate surface; a chip disposed on the substrate surface and comprising a semiconductor optical detection region; at least one light source disposed on the substrate surface; and an abrasion-proof layer formed on a chip surface of the chip without an optical mechanism for image scaling between the substrate surface and the abrasion-proof layer, and a distance from the chip surface to an upper surface of the abrasion-proof layer is smaller than 100 micrometers, wherein the upper surface of the abrasion-proof layer is configured to be directly in contact with a body surface of the part of human body when detecting the biometric characteristic such that light emitted from the light source directly illuminates the body surface and sequentially passes through the part of human body and the abrasion-proof layer to be detected by the semiconductor optical detection region.
