Abstract: Methods, systems, and apparatuses for wafer-level package-on-package structures are provided herein. A wafer-level integrated circuit package that includes at least one die is formed. The wafer-level integrated circuit package includes redistribution interconnects that redistribute terminals of the die over an area that is larger than an active-surface of the die. Electrically conductive paths are formed from the redistribution interconnects at a first surface of the wafer-level integrated circuit package to electrically conductive features at a second surface of the wafer-level integrated circuit package. A second integrated circuit package may be mounted to the second surface of the wafer-level integrated circuit package to form a package-on-package structure. Electrical mounting members of the second package may be coupled to the electrically conductive features at the second surface of the wafer-level integrated circuit package to provide electrical connectivity between the packages.

Abstract: According to one exemplary embodiment, a lead frame package includes a number of leads and a number of contacts, where each of the contacts is situated over one of the leads. The lead frame package further includes a semiconductor die including a number of bond pads. Each of the contacts is directly attached and bonded to one of the bond pads on the semiconductor die. Each of the contacts is situated over a top portion of one of the leads, where the top portion has a shorter length than a middle portion of each of the leads. Each of the contacts is connected to one of the bond pads on the semiconductor die without a wire bond. The semiconductor die does not include a redistribution layer situated over an active surface of the semiconductor die.

Abstract: Forming a wafer level chip scale flip chip package includes determining isolation requirements of an integrated circuit formed in a semi conductive substrate from package signal connections of the wafer level chip scale flip chip package. Operation may further include, based upon the integrated circuit characteristics, selecting a thickness of at least one dielectric layer isolating a top metal layer of the integrated circuit from the package signal connections of the wafer level chip scale flip chip package, determining a minimum pitch of the package signal connections of the wafer level chip scale flip chip package, and determining a maximum lateral distance from the signal pad to a servicing package signal connection of the wafer level chip scale flip chip package and determining a position of the servicing package signal connection of the wafer level chip scale flip chip package based upon the maximum lateral distance.
