Abstract

Official abstract text for this publication.

In some examples, a sensor package includes a semiconductor die having a sensor; a mold compound covering a portion of the semiconductor die; and a cavity formed in a top surface of the mold compound, the sensor being in the cavity. The sensor package includes an adhesive abutting the top surface of the mold compound, and a semi-permeable film abutting the adhesive and covering the cavity. The semi-permeable film is approximately flush with at least four edges of the top surface of the mold compound.

First claim

Opening claim text (preview).

What is claimed is: 1 . A semiconductor package, comprising: a semiconductor die including a sensor; a mold compound covering a portion of the semiconductor die; a cavity formed through the mold compound over the sensor; an adhesive layer disposed over the mold compound; and a film disposed over the adhesive layer, wherein the film includes an orifice at a corner of a top surface of the semiconductor package. 2 . The semiconductor package of claim 1 , wherein the adhesive layer includes at least one edge that is flush with at least one edge of the mold compound. 3 . The semiconductor package of claim 1 , further comprising: a second cavity formed through the adhesive layer over the sensor. 4 . The semiconductor package of claim 1 , further comprising: a second cavity formed through the adhesive layer, wherein the second cavity is aligned with the cavity. 5 . The semiconductor package of claim 1 , wherein a corner of a top surface of the adhesive layer is exposed to an exterior of the semiconductor package. 6 . The semiconductor package of claim 1 , wherein the film includes at least one edge that is flush with at least one edge of the mold compound. 7 . The semiconductor package of claim 1 , wherein the film is a semi-permeable film. 8 . The semiconductor package of claim 7 , wherein the semi-permeable film covers the cavity. 9 . The semiconductor package of claim 1 , wherein the semiconductor package is a quad flat no-lead (QFN) style sensor package. 10 . A semiconductor package, comprising: a semiconductor die including a sensor; a mold compound covering at least a portion of the semiconductor die; a first cavity extending through the mold compound over the sensor; an adhesive layer disposed over the mold compound; a second cavity extending through the adhesive layer, the second cavity is aligned with the first cavity; and a film disposed over the adhesive layer, wherein the film includes an orifice at a corner of a top surface of the semiconductor package. 11 . The semiconductor package of claim 10 , wherein the adhesive layer includes at least one edge that is flush with at least one edge of the mold compound. 12 . The semiconductor package of claim 10 , wherein a corner of a top surface of the adhesive layer is exposed to an exterior of the semiconductor package. 13 . The semiconductor package of claim 10 , wherein the film includes at least one edge that is flush with at least one edge of the mold compound. 14 . The semiconductor package of claim 10 , wherein the film is a semi-permeable film that covers the first cavity and the second cavity. 15 . The semiconductor package of claim 10 , wherein the semiconductor package is a quad flat no-lead (QFN) style sensor package.
