Abstract
In accordance with the present invention, there is provided multiple embodiments of a reduced size stackable semiconductor package. In a basic embodiment of the present invention, the semiconductor package comprises a bulk layer having at least one first bond pad formed therein. At least one active layer is formed on the bulk layer and electrically coupled to the first bond pad. Additionally, at least one second bond pad is formed on the active layer and is electrically coupled thereto. A protection layer is formed on that surface of the active layer having the second bond pad formed thereon, the protection layer also partially encapsulating the second bond pad. In other embodiments of the present invention, the above-described semiconductor package is provided in a stacked arrangement and in a prescribed pattern of electrical communication with one or more additional, identically configured semiconductor packages. In these stacked arrangements, one or more interposers and/or solder balls may optionally integrated into such semiconductor package stacks. In other embodiments of the present invention, a semiconductor package is provided wherein a semiconductor package stack is itself electrically connected to a substrate and covered with an encapsulant material which ultimately hardens into a package body.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
