EXTREMELY HIGH DENSITY SILICON CAPACITOR
This abstract first appeared for US patent application 20250006780 titled 'EXTREMELY HIGH DENSITY SILICON CAPACITOR
Original Abstract Submitted
a pillar or trench structure in a substrate includes vertical portions and one or more indented cavities in a sidewall between the vertical portions. the indented cavities are partial undercuts substantially traverse to the vertical portions pillar structure, or separate undercuts attached to an anchor. a higher capacitance density is achieved through the layering of multiple conductive contact layers and insulating layers in the undercuts and the vertical portions of the pillar or trench structure.
