  • Patent number: 11898082
    Abstract: This invention describes resins with phosphate cores and a simple, three-step process for their synthesis. Preferred resins are cyanate ester resins with bridging phosphate groups. These resins can be cured to produce thermoset polymers having Tgs of between 131 and >360° C. depending on the number of cyanate ester groups per phosphate and the substitution pattern of the aromatic rings. The high char yields of these resins, up to about 67%, coupled with the phosphate core means that these materials will have applications as fire-resistant polymers. Additionally, these materials can potentially be blended with conventional cyanate esters or other compatible thermosetting resins to improve the fire resistance of composite materials. Other applications may include use in fire-resistant circuit boards, or as surface coatings to reduce flammability of conventional composite materials or thermoplastics.

  • Patent number: 11848292
    Abstract: Embodiments described herein provide techniques for forming an interconnect structure that includes micro features formed therein. Such embodiments can assist with improving interconnect joint reliability when compared to conventional pads that have a flat surface. An interconnect structure may comprise: a metal pad over a substrate (e.g., a semiconductor package, a PCB, an interposer, etc.). Micro features may be formed in an edge of the metal pad or away from the edge of the metal pad. The micro features can assist with: (i) increasing the contact area between solder used to form an interconnect joint and the metal pad; and (ii) improving adherence of solder used to form an interconnect joint to the metal pad. These benefits can improve interconnect joint reliability by, among others, improving the interconnect joint's ability to absorb stress from substrates having differing coefficients of thermal expansion.
