Image sensor device with sensing surface cavity and related methods

This invention describes a camera component that protects its sensitive image sensor. The sensor chip sits on a base, surrounded by a protective covering that leaves its light-sensing surface open. Above this surface, an optical plate, which can be an infrared filter, creates a small air gap, and a lens assembly focuses light onto the sensor.

Why it matters: Since 2015, the demand for highly integrated and robust camera modules in compact devices has surged. Advances in micro-fabrication and packaging technologies could make the precise assembly of this protected sensor with its internal cavity and integrated optical filter more feasible and cost-effective.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedCustom silicon, optical components, precise assembly.
