Image sensor module and method of manufacturing the same
An image sensor module having a light gathering region and a light non-gathering region includes an image sensor, a light blocking spacer, a lens layer and a fixing shell. The light blocking spacer is disposed on the image sensor and located in the light non-gathering region. The light blocking spacer has a through hole exposing a portion of the image sensor in the light gathering region. The lens layer is disposed on the light blocking spacer and covers the through hole. The lens layer includes a transparent substrate and a lens disposed on the transparent substrate and located in the light gathering region. The fixing shell located in the light non-gathering region wraps the sidewalls of the image sensor, the light blocking spacer and the lens layer continuously. The material of the fixing shell includes a thermosetting material. A method for manufacturing the image sensor module is also provided.
1. A method of manufacturing an image sensor module, the image sensor module having a light gathering region and a light non-gathering region, the method comprising:
providing an image sensor, a first light blocking spacer and a lens layer, wherein the first light blocking spacer is disposed on the image sensor and is located in the light non-gathering region, the first light blocking spacer has a first through hole, the first through hole exposes a portion of the image sensor in the light gathering region, the lens layer is disposed on the first light blocking spacer and covers the first through hole, the lens layer comprises a transparent substrate and a first lens, the first lens is disposed on the transparent substrate and located in the light gathering region; and
forming a fixing shell on sidewalls of the image sensor, the first light blocking spacer and the lens layer, the fixing shell located in the light non-gathering region, a material of the fixing shell comprising a thermosetting material,
wherein the method of forming the fixing shell comprises:
coating an opaque material on the sidewalls of the image sensor, the first light blocking spacer and the lens layer to form an opaque material layer; and
coating the thermosetting material on the sidewalls of the image sensor, the first light blocking spacer and the lens layer to form a thermosetting material layer, and the thermosetting material layer overlapping with the opaque material layer.
2. The method of claim 1 , wherein when coating the thermosetting material, the thermosetting material conformally and continuously covers the sidewalls of the image sensor, the first light blocking spacer and the lens layer.
3. The method of claim 1 , further comprising:
before coating the thermosetting material, forming a protection layer on a surface of the lens layer away from the first light blocking spacer, wherein the protection layer is at least located in the light gathering region; and
after coating the thermosetting material, removing the protection layer.
