The future of computer chips may be just a few atoms thick. According to a report from Digitimes, three of the most important names in the semiconductor world — chipmaker TSMC, equipment giant ASML and the Belgian research hub Imec — have shown a way to bring so-called 2D transistors closer to real-world production.
Digitimes reports that Imec, ASML and TSMC have demonstrated a 300mm integration route for transistors built from 2D materials. In plainer terms, the team showed it could fabricate these devices on the standard large silicon wafers (300 millimeters across) that today's chip factories already use, rather than only in small lab experiments.
The work covered both of the basic transistor types needed to build working logic — n-type and p-type field-effect transistors. Building both on the same manufacturing line is a key requirement for making practical circuits.
The central idea is the use of "atomically thin channel materials," according to Digitimes — the part of a transistor that carries current, here made just a single layer or so of atoms thick. As traditional silicon transistors get harder to shrink, these ultra-thin materials are seen as a candidate to keep chips improving.
Digitimes frames the demonstration as a step toward moving these atomically thin materials out of the research lab and toward manufacturing, though it stops short of describing a finished, commercial process.
Why it matters: if these atom-thin transistors can be made reliably on existing factory equipment, it points to a path for keeping chips faster and more efficient once conventional silicon shrinking runs out of room.
