摘要:
A method of making a carbon nanotube structure includes providing an array of substantially aligned carbon nanotubes, wetting the array with a liquid, and evaporating the liquid to form the carbon nanotube structure having a pattern in the carbon nanotube array. The structure is preferably a carbon nanotube foam.

A treatment for a microelectronic device comprises a dicing tape (110) and a polymer composite film (120) having a pigment or other colorant added thereto and, in some embodiments, a pre-cure glass transition temperature greater than 50° Celsius. The film can comprise multiple layers, with one layer being tacky and the other layer non-tacky at a given temperature.

The present invention relates to a filler featuring a negative coefficient of thermal expansion and a bi-modal size distribution of filler particles. In an embodiment, the filler has micron and nanometer size filler particles. The present invention also relates to a composite having a polymer and a filler with nanometer size filler particles. Additionally, the present invention discloses a method of forming an electronic package with a composite having a polymer and a filler with nanometer size filler particles.
摘要:
Spreading or keep out zones may be formed in integrated circuit packages by altering the roughness of package surfaces. The surface roughness can be altered by applying or growing particles having a dimension less than 500 nanometers. Hydrophilic surfaces may be made hemi-wicking and hydrophobic surfaces may be made hemi-wicking by particles of the same general characteristics.
摘要:
According to one embodiment, a polymer coating is disposed on a surface of a package substrate. The polymer coating comprises a material capable of inhibiting the flow of an underfill material into a keep-out zone (KOZ). In a further embodiment, a die is disposed on the substrate and a layer of the underfill material is disposed between the die and substrate, and the polymer coating inhibits the flow of the underfill into the KOZ. Other embodiments are described and may be claimed.
摘要:
The flow of polymer formulations in in integrated circuit packages can be controlled by altering the roughness and surface chemistry of package surfaces. The surface roughness can be altered by forming protrusions having a dimension less than 500 nanometers and their chemistry can be controlled by chemical or plasma treatment. Hydrophilic surfaces may be made hemi-wicking and hydrophobic surfaces may be super-hydrophobic by particles of the same general characteristics.
