The most advanced sub-5nm silicon nodes require the latest EUV (extreme ultraviolet) lithography tools like the one above, but Chinese chipmakers are stuck with DUV (deep ultraviolet) lithography.

Rising U.S.-China tensions and the potential for a Taiwan conflict will boost the onshoring of chip manufacturing in the U.S. and Europe. Chips that power tech in general and the AI revolution, in ...

Interestingly, DUV lithography at a wavelength of 193 nm has dominated the field much longer than originally expected, with a continual series of improvements prolonging its lifespan. The ...

Abstract: This paper uses 113Gb/s PAM4 transceiver in 5nm CMOS to demonstrate a 1.8Tb/s chiplet, over die-to-die extremely short-reach (XSR) intra-package links, in a 8-port configuration. The ...

While SMIC does have older DUV (Deep Ultraviolet) Lithography machines, the inability of Chinese firms to obtain EUV machines places them 10 to 15 years behind the West according to Fouquet in a ...

Abstract: Deep-UV (DUV) lithography has been developed to scale minimum feature sizes of devices on semiconductor chips to sub-half-micron dimensions. This paper reviews early manufacturing ...
