Latest Patents
Gremban's latest patents include groundbreaking innovations in the realm of multilayer integrated circuit (IC) chip interposers. His work focuses on two key patents: the Parallel Process Interposer (PPI) and the method of fabricating a multi-layer integrated circuit chip interposer. Both inventions leverage a thin polyimide film that is strategically circuitized with copper on both sides. One side may serve as a power or ground plane, while the opposite functions as a signal plane.
The manufacturing process involves laminating adhesive over the circuit patterns and drilling vias through the adhesive and polyimide film. Following this, metal (copper) is sputtered to coat the walls of the vias, with Polymer Metal Conductive (PMC) paste screened to partially fill these vias. The blanket metal is then sub-etched using the screened PMC as a mask, culminating in the stacking of layers to form the interposer. This innovative design ensures that the PMC bonds the layers together, providing electrical interconnections between them, resulting in a high yield and high-density integrated circuit.
