Abstract: A method for manufacturing an electronic device is provided. In the method for manufacturing an electronic device, a substrate is provided, a device layer is disposed on the substrate, and a photoresist layer is disposed on the device layer. Next, a photo mask is disposed on the photoresist layer, and a light source is used to firstly illuminate the photo mask to form a first exposure region. After that, a relative movement is made between the substrate and the photo mask, and the light source is used to secondly illuminate the photo mask to form a second exposure region, wherein the first exposure region partially overlaps the second exposure region. Afterwards, a pattern is developed on the substrate, the device layer is etched using a patterned photoresist layer as an etching mask, and then the patterned photoresist layer is removed.

Abstract: A method for manufacturing a sensing device is provided. The method includes: providing a substrate; forming a sensing unit on the substrate; forming a first light-shielding layer on the sensing unit; forming a first anti-reflection layer on the sensing unit; and patterning the first light-shielding layer and the first anti-reflection layer using a single lithography process to form a first pinhole corresponding to the sensing unit.
