BREAKING: While the U.S. poured billions into EUV fabs and export bans, China just built a chip that makes all of it irrelevant. No silicon. No EUV. No permission. The post-lithography era has begun.https://t.co/hRdcMCEf4P

A microchip with nearly 6,000 transistors, each only three atoms thick, is the most complex microprocessor made from a two-dimensional material to date, scientists in China say.
The new device was made using the semiconductor molybdenum disulfide, which consists of a sheet of molybdenum atoms sandwiched between two layers of sulfur atoms. Scientists hope 2D materials such as molybdenum disulfide will allow Moore’s Law to continue once it becomes impossible to make further progress using silicon.
“Although 2D materials have been widely advocated for more than a decade, the real limitation to their current development is not the performance of any single device, as many 2D electronic devices work very well at the laboratory level,” says Wenzhong Bao, a professor at Fudan University’s school of microelectronics, in Shanghai. “The reason why people continue to question the practicality of 2D materials is the lack of an integrated technology system that is scalable, repeatable, and compatible with industrial processes.”
