▎ 摘　　要

NOVELTY - A graphene-based transistor comprises polycyclic aromatic hydrocarbon (PAH) molecules provided on a substrate surface, a gate stack arranged on portion(s) of the PAH molecules, and 2 or more conductive source/drain terminals electrically coupled to the PAH molecules. The PAH molecules have a lateral dimension in the plane of the substrate surface of 1 nm or more. USE - Graphene-based transistor is used for graphene-based interconnect trace-containing device (claimed). Uses include but are not limited to volatile dynamic random-access memory, non-volatile random-access memory, flash memory, graphics processor, digital signal processor, crypto processor, camera, touchscreen display, touchscreen controller, accelerometer, etc. ADVANTAGE - The high-performance graphene-based transistor has suppressed defects, and comprises polycyclic aromatic hydrocarbon molecules having excellent fluidity, mechanical strength and thermal conductivity. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) graphene-based interconnect trace-containing device, which comprises the substrate, a two-dimensional array of template structures arranged on the substrate, and a linear array of the PAH molecules arranged over the substrate surface between adjacent template structures. The linear array comprises 2 layers of the PAH molecules; (2) fabrication of graphene-based transistor, which involves forming nano diameter through-substrate vias (TSVs) extended through an insulating substrate, depositing molecular graphene on a front side substrate surface between the TSVs, forming (140) gate stack over the molecular graphene, backfilling the TSVs with a conductive material from a backside of the substrate, and forming local source/drain interconnect on the substrate backside contacting conductive material in pair of the TSVs; and (3) fabrication of graphene-based interconnect line, which involves forming a two-dimensional array of TSVs extended through an insulating substrate, depositing PAH molecules on the substrate surface sites interstitial to the array of TSVs to form a linear array of PAH molecules, and condensing (180) 1 or more additional layers of molecular graphene over the linear array.
