Substrate structures for image sensor modules and image sensor modules including the same

A substrate structure for an image sensor module, the substrate structure comprising:

• a module substrate having an upper surface and a lower surface, the module substrate including a sensor mounting hole;
• a reinforcing plate on a lower surface of the module substrate, the reinforcing plate covering the sensor mounting hole;
• an image sensor chip on the reinforcing plate within the sensor mounting hole, such that an upper surface of the image sensor chip is exposed by the module substrate;
• and
• a reinforcing pattern in at least a portion of the module substrate, the reinforcing pattern extending within the module substrate around the sensor mounting hole.

An image sensor module, comprising:

• a module substrate having an upper surface and a lower surface, the module substrate including a sensor mounting hole;
• a reinforcing plate on a lower surface of the module substrate, the reinforcing plate covering the sensor mounting hole;
• an image sensor chip on the reinforcing plate within the sensor mounting hole, such that an upper surface of the image sensor chip is exposed by the module substrate;
• a reinforcing pattern in at least a portion of the module substrate, the reinforcing pattern extending within the module substrate around the sensor mounting hole;
• and
• an optical system on the upper surface of the module substrate, the optical system configured to focus light received from an external object to the image sensor chip.
