Methods, systems, and apparatuses for semiconductor devices are provided herein. A semiconductor device includes an array of conductive pads for signals. One or more non-linear compliant springs may be present to route signals from the conductive pads to interconnect pads formed on the semiconductor device to attach bump interconnects. Each non-linear compliant spring may include one or more routing segments. The semiconductor device may be mounted to a circuit board by the bump interconnects. When the semiconductor device operates, heat may be generated by the semiconductor device, causing thermal expansion by the semiconductor device and the circuit board. The semiconductor device and circuit board may expand by different amounts due to differences in their thermal coefficients of expansion. The non-linear compliant springs provide for compliance between the conductive pads and bump interconnects to allow for the different rates of expansion.

Flexible routing for chip on board applications

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.

Package-on-package technology for fan-out wafer-level packaging

Methods, systems, and apparatuses for wafer-level integrated circuit (IC) packages are described. An IC package includes an IC chip, an insulating layer on the IC chip, a plurality of vias, a plurality of routing interconnects, and a plurality of bump interconnects. The IC chip has a plurality of terminals configured in an array on a surface of the IC chip. A plurality of vias through the insulating layer provide access to the plurality of terminals. Each of the plurality of routing interconnects has a first portion and a second portion. The first portion of each routing interconnect is in contact with a respective terminal of the plurality of terminals though a respective via, and the second portion of each routing interconnect extends over the insulating layer. Each bump interconnect of the plurality of bump interconnects is connected to the second portion of a respective routing interconnect of the plurality of routing interconnects.
