Abstract
Embodiments include but are not limited to apparatuses and systems including semiconductor packages, e.g. memory packages, having an interposer including at least one topological feature, such as a depression in a surface of the interposer, a die coupled to the surface of the interposer, and an encapsulant material formed over the die and the interposer, and disposed in the at least one depression to resist movement of the encapsulant material relative to the interposer. Other embodiments may be described and claimed.
Claims14
A method of manufacturing a semiconductor device package, the method comprising:
- forming at least one depression in a top surface of an interposer, wherein the interposer includes a soldermask, and wherein forming the at least one depression includes forming an opening in a portion of the top surface located in a gap between first and second bond pads at the top surface and such that the opening extends from a surface of the soldermask to an underlying metal region of the interposer;
- coupling a die to the top surface of the interposer;
- and
- disposing an encapsulant over the die and the interposer, and such that the encapsulant is disposed within the at least one depression.
A method of manufacturing a semiconductor device package, the method comprising:
- forming at least one depression in a top surface of an interposer, wherein the interposer includes a soldermask, wherein forming the at least one depression includes forming an opening in a portion of the top surface located in a gap at a corner of the interposer and between first and second bond pads at the top surface, and wherein the opening extends from a surface of the soldermask to an underlying metal region of the interposer;
- coupling a die to the top surface of the interposer;
- and
- disposing an encapsulant over the die and the interposer, and such that the encapsulant is disposed within the at least one depression.
A method of forming a semiconductor device package, the method comprising:
- forming a first bond pad on an interposer and adjacent a first peripheral edge at a corner of the interposer;
- forming a second bond pad on the interposer and adjacent a second peripheral edge at the corner of the interposer;
- forming at least one depression in a soldermask of the interposer, wherein the at least one depression is located in a gap between the first and second bond pads, and wherein the at least one depression extends from a surface of the soldermask to an underlying metal region of the interposer;
- attaching a die to the interposer;
- and
- disposing an encapsulant over the die and the interposer, and such that the encapsulant is disposed within the at least one depression.
