Pseudo-translucent integrated circuit package
First Claim
1. An integrated circuit package comprising:
- an integrated circuit structure defining a biometric sensor;
a plurality of light sources positioned around a periphery of said biometric sensor; and
a semi-opaque encapsulation material, encapsulating at least a portion of said integrated circuit structure and said plurality of light sources such that said plurality of light sources and at least a portion of said integrated circuit structure are not visible to the unaided human eye, and configured so that light emitted from said plurality of light sources is visible to the unaided human eye through at least a portion of said semi-opaque encapsulation material to provide visual feedback to a user.

Abstract
An integrated circuit (IC) package includes at least one light source disposed together with an IC structure within an encapsulation structure. The material forming the encapsulation structure is generally opaque. Accordingly, the light source and at least a portion of the IC are not visible to the unaided human eye. The thickness and geometry of the encapsulation are such that when the light source is caused to emit light, the encapsulation structure permits at least a portion of that light to be visible to a user. The IC may be a portion of a fingerprint sensor, exposed for receiving a fingertip of a user. The light source, or a plurality of such light sources, may be functional (e.g., providing visual indication of the of the condition or state of an item of hardware or software, assist the user in operation of a device), be primarily aesthetic, or a combination thereof.
