摘要:
A method for assembling, and the resultant electronic module, includes attaching a chip to a substrate using a first solder interconnection array, and attaching a board to the substrate using a second solder interconnection array, which may be a single-melt or a dual-melt solder array. The second solder interconnection array resides entirely within a space defined between the board and substrate. A creep resistant structure is provided within this space for maintaining the defined space and optimizing integrity of the second solder interconnection array. The creep resistant structure may include an underfill material, balls, brackets, frames, collars or combinations thereof. Wherein the creep resistant structure is an underfill material, it is crucial that the substrate be attached to the board before either entirely encapsulating the second interconnection array with underfill material, or partially encapsulating the second solder interconnection array at discrete locations with underfill material.

A method of acidizing and cleaning up a formation is disclosed, the formation being above 150 degrees C. The formation is treated with a mutual solvent system comprising a mutual solvent of oil and water, an aqueous acid, a corrosion inhibitor, and an iron control agent. In some embodiments, the iron control agent is present in an amount of less than 1% by weight of the mutual solvent system. In some embodiments, the corrosion inhibitor may be present in an amount of less than 10% by weight of the mutual solvent system. In some embodiments, the mutual solvent system further comprises an intensifier.

Methods for treating an individual having cancer are provided. The method may include administering a cell migration inhibitor and a chemotherapeutic agent to the individual to inhibit migration of cancer cell. Inhibiting cell migration may increase cell division. In this manner, the cell migration inhibitor and the chemotherapeutic agent in combination may have increased efficacy compared to the chemotherapeutic agent alone due to the increased cell division. The cell migration inhibitor may include any of the inhibitors described herein. For example, the cell migration inhibitor may be an organic molecule having a molecular weight of less than about 700, a monoclonal antibody, or a natural product.

A semiconductor module structure and a method of forming the semiconductor module structure are disclosed. The structure incorporates a die mounted on a substrate and covered by a lid. A thermal compound is disposed within a thermal gap between the die and the lid. A barrier around the periphery of the die extends between the lid and the substrate, contains the thermal compound, and flexes in response to expansion and contraction of both the substrate and the lid during cycling of the semiconductor module. More particularly, either the barrier is formed of a flexible material or has a flexible connection to the substrate and/or to the lid. The barrier effectively contains the thermal compound between the die and the lid and, thereby, provides acceptable and controlled coverage of the thermal compound over the die for heat removal.

A heat spreading apparatus for use in cooling of semiconductor devices includes a frame having a plurality of individual cells formed therein, each of the cells configured for filling with a material of selected thermal conductivity therein. The selected thermal conductivity of material within a given one of the cells corresponds to a thermal profile of the semiconductor device to be cooled.

A chip package including a chip extension for containing thermal interface material (TIM) and improves chip cooling, and a related method, are disclosed. In particular, the chip package includes a chip, a cooling structure coupled to the chip via a TIM, and a chip extension may be thermally coupled to an outer edge of the chip. A TIM placed between the chip and the cooling structure is contained during thermal cycling by the chip extension such that void formation at the edge of the chip, which can move between the chip and cooling structure, is suppressed. The chip extension also improves lateral heat dissipation by providing a greater thermal contact area between the cooling structure and the chip and, if needed, the substrate at a much lower cost than using larger die with lower production unit output from a wafer.

The present invention relates generally to a new apparatus and method for introducing thermal paste into semiconductor packages. More particularly, the invention encompasses an apparatus and a method that uses at least one preform of thermal paste for the cooling of at least one chip in a sealed semiconductor package. The thermal paste preform is subcooled, and is transferred onto a module component from a separable transfer sheet, or is placed onto the module component using an attached and/or imbedded mesh. The preform of thermal paste may be of simple or complex shape, and enables cooling of one or more chips in a module.
