RESIN COMPOSITION AND CURED PRODUCT THEREOF
An object of the present invention is to provide an adhesive having sufficient adhesion strength during heat-curing when a lens holder and a substrate on which an imaging element is fixed are bonded in camera module assembly, and also having excellent adhesion strength and position accuracy after a high-temperature and high-humidity durability test after curing. The present invention relates to a resin composition comprises (a) a (meth)acrylate group-containing resin, (b) a specific polyfunctional thiol, and (c) a latent curing agent.

Dielectric for high density substrate interconnects
The present disclosure is directed to systems and methods for providing a dielectric layer on a semiconductor substrate capable of supporting very high density interconnects (i.e., ≥100 IO/mm). The dielectric layer includes a maleimide polymer in which a thiol-terminated functional group crosslinks with an epoxy resin. The resultant dielectric material provides a dielectric constant of less than 3 and a dissipation factor of less than 0.001. Additionally, the thiol functional group forms coordination complexes with noble metals present in the conductive structures, thus by controlling the stoichiometry of epoxy to polyimide, the thiol-polyimide may beneficially provide an adhesion enhancer between the dielectric and noble metal conductive structures.
Network polymers and methods of making and using same
The present invention relates to covalent adaptable networks (CANs) having exchangeable crosslinks that are able to undergo repeated covalent bond reshuffling through photo-activation at ambient temperatures. The invention provides covalent adaptable network forming compositions as well as methods of forming, remolding and recycling the CANs of the invention.
