Title: Innovations by Inventor Chandrasekaram Ramiah
Introduction
Chandrasekaram Ramiah is a notable inventor based in Phoenix, AZ (US). He has made significant contributions to the field of integrated circuits, holding a total of 10 patents. His work focuses on advanced methods for forming three-dimensional circuits with integrated passive devices.
Latest Patents
One of his latest patents involves methods of forming 3-D integrated circuits (ICs) with integrated passive devices (IPDs). This innovative approach includes stacking separately prefabricated substrates. An active device (AD) substrate features contacts on its upper portion, while a ground plane is strategically located between the AD substrate and an IPD substrate. This ground plane enhances IPD to AD cross-talk attenuation, improving overall circuit performance. Another patent details methods of forming 3-D ICs with IPDs that utilize through-substrate vias (TSVs) for coupling. In this method, an isolator substrate is bonded to the AD substrate, allowing TSVs in the isolator substrate to connect with the contacts on the AD substrate. The IPD substrate is then bonded to the isolator substrate, facilitating connections to an interconnect zone and TSVs. This design not only provides superior cross-talk attenuation but also allows for high circuit packing density and efficient manufacturing.
