NdFeB POLYMER MAGNET COMPOSITE INCLUDING POLYCARBONATE MATRIX AND PROCESSING THEREOF
Polymer magnet composites including NdFeB in a polycarbonate (PC) binder matrix are processed using processes including batch mixing and twin screw extrusion. One method includes adding PC to a compartment of a batch mixer and mixing the PC while the compartment is at a temperature greater than a flow temperature of the PC, to form a mixed PC material. The method also includes adding a NdFeB magnetic material to the compartment with the mixed PC material in four batches while the compartment is at the temperature greater than the flow temperature of the PC to form a mixed PC and NdFeB magnetic material, wherein each batch is mixed in the compartment for 1 to 3 minutes before the next batch is added. In addition, a total mixing time is 6 to 12 minutes, and the compartment includes an inert atmosphere. Other embodiments are described and claimed.

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.
