Abstract:
Embodiments of the present invention are directed generally to methods for producing high purity exo-alkenylnorbornenes from a mixture of conformational isomers thereof.
Abstract:
Embodiments in accordance with the present invention encompass negative-tone, aqueous base developable, self-imageable polymer compositions useful for forming films that can be patterned to create structures for microelectronic devices, microelectronic packaging, microelectromechanical systems, optoelectronic devices and displays.
Abstract:
Embodiments according to the present invention relate to sacrificial polymer compositions that include polycarbonate polymers having repeat units derived from stereospecific polycyclic 2,3-diol monomers. The sacrificial polymer compositions also include an acid generator that is selected from at least one photoacid generator and/or at least one thermal acid generator. In addition, embodiments according to the present invention relate to a method of forming a structure that includes a three-dimensional space interposed between a substrate and an overcoat layer, and a method of temporarily bonding first and second substrates together, which make use of the polycarbonate polymers.
Abstract:
Embodiments in accordance with the present invention encompass polymer compositions that are useful in the assembly of microelectronic components onto a variety of substrate materials. Such polymer compositions providing for both holding the microelectronic components at desired positions on a substrate, providing fluxing for the solder bonding of such components to the substrate and remaining in place as an underfill for such components.
Abstract:
Embodiments in accordance with the present invention provide sacrifical polymer compositions and methods for fabricating electronic devices using such sacrifical polymer compositions where such methods include (1) providing a tacky sacrifical polymer composition that holds components in a desired alignment to one another, (2) providing solder fluxing for effecting electrical coupling; and (3) thermal decomposition or depolymerization of the sacrificial polymer composition to provide essentially residue free surfaces.
