    摘要: A semiconductor component (10) having a photodefinable stress compensation layer (21) and composition for the stress compensation material. The photodefinable stress compensation material is formed on a semiconductor wafer (11) and openings (22) are made photolithographically. Conductive bumps (26) are then disposed thereon and additional conductive bumps (28) are formed on the original conductive bumps (26). The photodefinable stress compensation material is composed of a photoinitiator, an epoxy having a first index of refraction, a diluent, and a filler. The indices of refraction of the epoxy-diluent combination and the filler are approximately equal. Alternatively, the photodefinable stress compensation material can be formed on a semiconductor wafer (11) having conductive bumps (46) disposed thereon. Openings (49) are formed in the stress compensation layer (47) to expose the conductive bumps (46). Additional conductive bumps (51) are formed on the original conductive bumps (46).

    摘要: A solder flux composition (19) is provided which comprises active ingredients and a carrier. The solder flux composition undergoes a phase separation during solder reflow to form at least a first phase (21) and a second phase (23), such that the active ingredients are disposed primarily in the first phase and the carrier is disposed primarily in the second phase. The use of this solder flux composition is found to reduce solder migration, during solder reflow, that can result in bridging in ball grid arrays and other such devices.

    摘要: Optically nonlinear device elements such as directional couplers, switches, frequency stabilizers, optical parametric devices and modulators use as an optically nonlinear element a cross-linked triazine polymer containing a covalently bonded optically nonlinear dye moiety. A specific cross-linked triazine with this dye moiety may be made by cyclotrimerizing a p-(N,N-bis(4'-cyanatobenzyl)amino)-p'-(2,2-dicyanovinyl)azobenzene monomer. During polycyclotrimmerization or cure, the element is subjected to a poling voltage which aligns the dipoles of the dye moiety to give a large useful nonlinear susceptibility.

    摘要: Contacts of an electrical device can be made of carbon nanotube columns. Contact tips can be disposed at ends of the columns. The contact tips can be made of an electrically conductive paste applied to the ends of the columns and cured (e.g., hardened). The paste can be applied, cured, and/or otherwise treated to make the contact tips in desired shapes. The carbon nanotube columns can be encapsulated in an elastic material that can impart the dominant mechanical characteristics, such as spring characteristics, to the contacts. The contacts can be electrically conductive and can be utilized to make pressure-based electrical connections with electrical terminals or other contact structures of another device.
