Systems and methods for encapsulating a stack of semiconductor dice are described. A stack of semiconductor dice may be formed, for example by attaching die to flexible printed circuit supports attached to frames and stacking the supports, and then encapsulated by flowing a liquid encapsulant around the stack of dice and solidifying the liquid encapsulant. The die supports may contain encapsulant flow openings, such as rectangular slits, that allow the liquid encapsulant to flow around the stack of dice.

A system may include an integrated circuit die, an integrated circuit package coupled to the integrated circuit die, mold compound in contact with the integrated circuit die and the integrated circuit package, and an interconnect coupled to the integrated circuit package. A first portion of the interconnect may be in contact with the mold compound, a second portion of the interconnect might not contact the mold compound, and a third portion of the interconnect may be in contact with the integrated circuit package.

Embodiments include a generally planar patch substrate having external connection pads on one side, electrical connections connected to the external connection pads and extending through the substrate, and plated contacts formed on the electrical connections and extending beyond the other side of the patch substrate. The external connection pads may be connected to one electrical device using solder bumps or balls, and the plated contacts may be connected to contacts of another electrical device by thermo-compression bonding. Also, a surface of the patch substrate having the plated contacts may be attached to the other electrical device using an electrically insulating adhesive. Moreover, the plated contacts may have a smaller surface area than the external connection pads, so that the other electrical device can also have smaller contacts, leaving more space for electrically conductive traces to the contacts on the surface and within layers of the other electrical device.

A socket for mounting a processor and/or a board has a substrate with a built in socket. The socket has conductive, elastically deformable terminals. The socket may be mounted to a processor and a board without using conventional surface mount technology, instead providing a mechanical contact mechanism between the socket and the board or processor. An adhesive layer may also be used to connect the socket to a processor and/or a board.

A method for producing a molded flip chip package is described. The incomplete flip chip package comprising a thin substrate and a silicon chip is placed in a mold. A resin, preferably epoxy, is injected into the mold filling the gap between the surface of the flip chip and the adjacent substrate. Additionally, a stiffening structure is formed to increase the overall rigidity of the thin substrate specifically and the package as a whole.
摘要:
A method of fabricating an electronic package. The method includes filling a mold with an electric conductor to form a number of electrical interconnects within the mold. The mold includes openings that are filled with several electric conductors to form a number of electrical interconnects. The method of fabricating an electronic package further includes attaching the mold to a substrate such that the electrical interconnects engage electrical contacts on the substrate. The method of fabricating an electronic package may further include forming conductive pads on the electrical insulator that engage the electrical interconnects and attaching a die to the substrate such that the die is electrically connected to at least some of the electrical interconnects.
