TSMC working in direction of a future with trillion-transistor chips, 1nm-class manufacturing


The massive image: The worldwide firm confirmed the way it plans to proceed rising transistor density over the following a number of years. It additionally believes that the semiconductor trade will transition to chiplet-based designs as nicely.

On the latest IEDM convention, TSMC unveiled a product roadmap for its semiconductors and next-generation manufacturing nodes that culminates in finally delivering a number of 3D-stacked collections of chiplet designs (3D Hetero Integration) with one trillion transistors on a single chip package deal. Developments in packaging applied sciences, reminiscent of CoWoS, InFO and SoIC, will enable it to succeed in that aim and by 2030 it believes that its monolithic designs might attain 200 billion transistors.

Nvidia’s 80-billion-transistor GH100 is likely one of the most subtle monolithic processors at the moment available on the market. Nevertheless, as the scale of those processors continues to develop and turn out to be extra pricey, TSMC believes that producers will undertake multi-chiplet architectures, reminiscent of AMD’s recently-launched Intuition MI300X and Intel’s Ponte Vecchio, which has 100 billion transistors.

For now, TSMC will proceed to develop 2nm-class N2 and N2P manufacturing nodes and 1.4nm-class A14 and 1nm-class A10 fabrication processes. The corporate expects to begin 2nm manufacturing by the top of 2025. In 2028, it would transfer onto a 1.4nm A14 course of, and by 2030, it expects to be producing 1nm transistors.

In the meantime, Intel is engaged on its 2nm course of (20A), and 1.8nm (18A), which it roughly expects to launch throughout the identical timeframe. One benefit of the brand new know-how is bottom energy supply, referred to as PowerVia, which ought to enable for larger logic densities, larger increase clock speeds, and decrease energy leakage, leading to extra energy-efficient designs that might outperform TSMC’s choices.

Because the world’s largest foundry, TSMC is assured its course of nodes will outperform something from Intel. In an earnings name, TSMC CEO C.C. Wei stated that an inner evaluation confirmed the enhancements of the N3P know-how and that its 3nm-class manufacturing node demonstrated “comparable PPA” to Intel’s 18A node. He expects N3P to be even higher, boasting a extra aggressive “know-how maturity” and having important price benefits.

Not one to disregard preventing phrases, Intel CEO Pat Gelsinger claimed that its 18A course of node will outperform TSMC’s 2nm chips regardless of launching a 12 months earlier.

The market will quickly have the ability to decide which is best. The Taiwan-based chip large expects to carry N3P into mass manufacturing within the second half of 2024 alongside its 20A and 18A merchandise.
