International Classification:

H01L 31/0232

US Classification:

257432, 257E31127

Abstract:

A device having a detector includes a sensor package. The sensor package includes a light sensor, at least one filter located over the light sensor and at least one bond pad. The light sensor is formed on a semiconductor device that provides sensor information related to light incident upon the light sensor. A perimeter of each bond pad is covered by a protective layer forming a sidewall seal. The sensor package also includes a package that encases the light sensor, filter(s) and bond pad(s). Additionally, at least one package pin is communicatively coupled to the bond pad(s). The device also includes a functional circuit that is coupled to the sensor package and receives the sensor information from the light sensor. The device can be an ambient light sensor, camera, backlit mirror, handheld electronic device, filter device, light-to-digital output sensor, gain selection device, proximity sensor, or light-to-voltage non-linear converter.
