🚨Semiconductor news🚨
China have made major breakthroughs in EUV lithography light source.
SSMB utilizes a synchrotron to accelerate and manipulate electron beams into EUV radiation.
This single light source can be hooked up to several lithography workstations

SSMB (Steady-State Microbunching) isn't a EUV lithography machine per se, it's more like an EUV lithography factory/ facility.
If ASML's lithography machines are your desktop printers, then these are printing factories.
HOWEVER, unlike many claimed online, this technology is still at least 5 years away.
China's upcoming EUV lithography machines still uses the traditional LPP EUV light source, same as ASML.
When optimized, the SSMB method can be more efficient and versatile.
