摘要

碳纳米管场效应管(cnfet)是下一代高性能和节能电子器件的优秀候选者,因为基于cnfet的数字电路有望在高规模技术节点上实现能量延迟产品的数量级改进。本文概述了完全使用cnfet实现的计算机的第一个演示。碳纳米管计算机能够执行多任务:作为演示,我们同时执行计数和整数排序。此外,我们还模拟了来自商业MIPS指令集的20条不同指令,以演示我们的碳纳米管计算机的通用性。这是迄今为止最复杂的碳基电子系统。这是一个相当大的进步,因为碳纳米管在下一代高能效电子系统中正在考虑的各种新兴技术中占有突出地位。除了性能和能源优势外,CNFET还提供了通过低温CNFET加工实现单片三维(3D)集成的独特机会。单片3D集成是一种有吸引力的技术选择,因为与硅通孔相比,它可以实现非常高密度的层间通孔。本文还将对单片三维CNFET集成电路的演示进行总结。

Advancements with carbon nanotube digital systems
Carbon Nanotube FETs (CNFETs) are excellent candidates for the next generation of high-performance and energy-efficient electronics, as CNFET-based digital circuits are projected to potentially achieve an order of magnitude improvement in energy-delay product at highly scaled technology nodes. This paper presents an overview of the first demonstration of a computer implemented entirely using CNFETs. The CNT computer is capable of performing multitasking: as a demonstration, we perform counting and integer-sorting simultaneously. In addition, we emulate 20 different instructions from the commercial MIPS instruction set to demonstrate the generality of our CNT computer. This is the most complex carbon-based electronic system yet demonstrated. It is a considerable advance because CNTs are prominent among a variety of emerging technologies that are being considered for the next generation of highly energy-efficient electronic systems. In addition to performance and energy benefits, CNFETs also provide a unique opportunity to achieve monolithic three-dimensional (3D) integration through low-temperature CNFET processing. Monolithic 3D integration is an attractive technological option because it enables a very high density of Inter-Layer Vias compared to Through-Silicon Vias. A summary of monolithic 3D CNFET integrated circuit demonstrations will also be given.
