摘要:
The invention provides bumps between a die and a substrate with a height greater than or equal to a height of a waveguide between the die and the substrate. The bumps may be formed on a die prior to that die being singulated from a wafer.

摘要:
A method of fabricating a microelectronic package having a direct contact heat spreader, a package formed according to the method, a die-heat spreader combination formed according to the method, and a system incorporating the package. The method comprises metallizing a backside of a microelectronic die to form a heat spreader body directly contacting and fixed to the backside of the die thus yielding a die-heat spreader combination. The package includes the die-heat spreader combination and a substrate bonded to the die.

A method for aligning at least two photonic components over an interposer, and an optical package that may align such components. The method may include providing an interposer; fabricating electrical conductors passing from one surface of the interposer to an opposite surface of the interposer at selected contact positions; soldering the photonic components over the selected contact positions on the first surface, while allowing solder self-alignment. Other embodiments are described and claimed.

A separable electrical connection may be provided with a landside pad on one of two electrical components to be joined. The landside pad may be made up of two parts, including a flat portion and a raised edge formed on the flat portion. In some embodiments, the raised edge may have a closed geometric shape. Then, a socket contact engaging the junction between the flat portion and the raised edge is prevented from sliding off of the landside pad by the raised edge. In addition, dual areas of electrical connection can be established between both the flat portion and raised edge of the landside pad and the correspondingly shaped pair of portions on the socket. This increases the electrical efficiency of the connection and its security.

An optical connector module complete with optoelectronic devices, supporting integrated circuitry, and connector housing may be fabricated on a wafer level. A plurality of cavities may be formed on the backside of the wafer to accommodate an optoelectronic device. Active circuitry may be formed in a front side of the wafer. Through-vias electrically connect the front side to the back side. The backside of the wafer is overmolded with a polymer layer which when singulated into individual dies forms the plastic housing of an optical connector module.
