As the electronics industry approaches the physical limit of transistor miniaturization, there is an ongoing shift towards a ‘skyscraper’ model in which transistors are stacked in layers on a single chip. Many unconventional materials have been explored for these 3D circuits, but none can yet compete with silicon, which remains the industry standard for high-performance 2D chips. Writing in Nature, Lam et al.1 report the creation of 3D transistor circuits constructed from stacked silicon nanomembranes. These flexible membranes are peeled off a substrate and stacked onto to the chip using a roller — a simple process that does not require high temperatures but achieves the high silicon-crystal quality that integrated circuits require.
