Abstract:
1. A method of manufacturing a semiconductor device comprising: providing a first substrate, the first substrate including a sacrificial layer, an active layer having an image sensor circuit portion and an interconnection layer electrically connected to the image sensor circuit portion sequentially stacked, performing an edge-trimming process with respect to the first substrate to form an interconnection layer pattern, an active layer pattern and a sacrificial layer pattern by, sequentially performing a dry etching process with respect to an edge of the interconnection layer and an edge of the active layer to form the interconnection layer pattern and the active layer pattern, and performing a dry etching process with respect to a portion of an edge of the sacrificial layer to form the sacrificial layer pattern; adhering the first substrate to a second substrate after performing the edge-trimming process; removing the sacrificial layer pattern to expose the active layer pattern; and forming a transillumination layer on the active layer pattern such that the active layer pattern is disposed between the transillumination layer and the interconnection layer pattern, the transillumination layer configured to transmit light to the image sensor circuit portion.
