An integrated circuit package strip employs a stiffener layer that houses a passive electronic component to maintain mechanical properties when a thinner substrate is used. The use of either a retention wall or a stiffener allows for the manufacture of these integrated circuit package using strip, matrix, or array technology where a larger board with a plurality of integrated circuit packages is produced industrially and then cut to individual units.

Integrated circuit package strip with stiffener

A method of manufacturing a semiconductor chip is disclosed. A die having a plurality of die-pads is attached to a substrate in a semiconductor package which includes a plurality of substrate-pads. The method involves forming conductive column bumps of differing volumes extending from the die-pads; attaching each of the column bumps to a corresponding substrate-pad to form a subassembly; and reflowing the subassembly so that the column bumps form robust electrical and mechanical connections between the die pads and the substrate pads.

Flip chip semiconductor assembly with variable volume solder bumps

Various semiconductor chip packages and methods of making the same are disclosed. In one aspect, a method of manufacturing is provided that includes coupling a solder bump to a side of a semiconductor chip and bringing the solder bump into contact with a conductor pad coupled to a substrate and positioned in an opening of a solder mask on the substrate. The conductor pad has a first lateral dimension and the opening has a second lateral dimension that is larger than the first lateral dimension. A metallurgical bond is established between the solder bump and the conductor pad.

Integrated package circuit with stiffener

A method of packaging a plurality of semiconductor chips comprises: providing a substrate panel having a first coefficient of thermal expansion (CTE); providing a carrier having a second CTE that is less than the first CTE; heating the substrate panel and the carrier to first and second elevated temperatures respectively; mounting the substrate panel at about the first elevated temperature to the carrier, the carrier being at said second elevated temperature, to provide a connection between the carrier and the substrate panel; and cooling the carrier and the substrate panel from the first and second elevated temperatures thereby putting the substrate panel into tension in at least one direction. A stiffener panel may be affixed to the substrate panel and heated to an elevated temperature and while the substrate panel is heated to an elevated temperature. A plurality of dies may be mounted and electrically connected to the substrate panel. Under-filling of the plurality of dies may occur with the stiffener panel affixed to the substrate panel.

Method and apparatus for making semiconductor packages

Various stacked semiconductor devices and methods of making the same are provided. In one aspect, a method of manufacturing is provided that includes providing a first semiconductor die that has a first bulk semiconductor side and a first opposite side. A second semiconductor die is provided that has a second bulk semiconductor side and a second opposite side. The second opposite side of the second semiconductor die is coupled to the first opposite side of the first semiconductor die. Electrical connections are formed between the first semiconductor die and the second semiconductor die.

Die stacking apparatus and method

A multi-die module is electrically connected to both an unpackaged die and a packaged die as disclosed herein. The multi-die module has a footprint that is the same as conventional multi-die packages, which do not include packaged die, thereby allowing the multi-die module to be interchangeable with conventional multi-die packages. In one embodiment, the unpackaged die is a graphics processor, and the packaged die is a standard memory that has been burned in, functionally tested, and speed rated.

Multi-die module

Multi-die module and method thereof

An integrated circuit package includes a first or active substrate and a second or passive substrate. The active substrate includes at least one circuit that generates heat during circuit operation. The passive substrate does not include any heat-generating circuits, although the passive substrate may include passive, disabled or dormant circuitry. The two substrates are preferably fabricated of semiconductor material and have substantially equal coefficients of thermal expansion. The passive substrate is thermally coupled to the active substrate preferably using a thin layer of adhesive, such as an epoxy. The passive substrate serves to thermally conduct the heat generated by the circuits of the active substrate away from the active substrate. An internal metallic heat sink may be optionally thermally coupled to the passive substrate to further aid in the transfer of heat away from the active substrate.

A solder ball collapse control apparatus and method thereof includes a plurality of first solder members, pieces of solder material in a shape capable of being used to properly create a solder joint. The first solder members have a first solder dimension and a first melting temperature and are disposed on a carrier substrate, wherein the first solder members include any piece of material capable of being disposed using a solder dispensing machine. The apparatus and method further includes a plurality of second members having a second dimension and a second melting temperature, disposed on the carrier substrate in relation to the plurality of first solder members. The second members include any piece of material capable of being disposed using the solder dispensing machine, wherein the first solder member dimension is greater than the second member dimension and the second melting temperature is greater than the first melting temperature.
