OPTICAL SENSOR PACKAGES WITH GLASS MEMBERS

Abstract:

In some examples, an optical sensor package comprises a semiconductor die; an opaque mold compound covering the semiconductor die and having a cavity; and an optical sensor on the semiconductor die and exposed to the cavity. The optical sensor package includes a glass member inside the cavity. The glass member abuts the sensor and a wall of the cavity. The glass member is exposed to an exterior environment of the optical sensor package. The glass member has a thickness approximately equivalent to a depth of the cavity.
