Company history
SMEE was established in 2002 by He Rongming, a former vice president at
Shanghai Electric. It was originally a lithography machine technology research project under the
863 Program
The 863 program () or State High-Tech Development Plan () was a program funded and administered by the government of the People's Republic of China intended to stimulate the development of advanced technologies in a wide range of fields for th ...
. After a few years of research, SMEE rolled out the first domestically made lithography machine for commercial use.
In December 2017, SMEE signed a contract with

Product history
Prior to 2023, SMEE's most advanced product for manufacturing front-end semiconductor chips was the SSA600, which has a scanning resolution that is capable of fabricating 90 nm-class integrated circuit silicon chips. The SSA600 series machines has been described by observers as an immersion deep ultraviolet lithography tool which features an argon fluoride (ArF)

SSA800x (December 2023)
In December 2023, western media reported that SMEE has completed the initial development of its new SSA800-10W

machine which has a scanning resolution capable of fabricating 28 nm-process class chips. Instances of the new machine may have been delivered to manufacturers such as
SMIC and to research institutes. SSA800 continues to use
ArF laser as its light source but also includes better tools and components which enable manufacturers to fashion circuit features associated with 28 nm-process technology.
Western media reported that SSA800 is designed so that none of its components include intellectual properties that originate in the United States .
Some analysts suggest that it is likely the Chinese government had asked SMEE to benchmark its new 28 nm-capable DUV immersion system against the similar
ASML NXT:2000i system and that SSA800 is part of a fully domestic production line which is currently undergoing test production and certification.
As of early 2024, SMEE's website does not yet include the new SSA800 lithography machine in its product list section.
In the future, a version of the SSA800 may be employed on processes below the 28 nm node via multi-patterning; generally, photolithography techniques developed in the field of

Pre-2023 product mix
Prior to the introduction of the SSA800 scanner series in 2023, SMEE had developed a range of lithography, metrology, and derivative equipment, including four series of machines for the manufacture of front-end integrated circuits (such as the SSA600 series scanners), back-end IC packaging,

EUV lithography
In 2024, SMEE filed a patent for an
EUV lithography scanner to manufacture advanced chips, which is currently only produced by Netherland's
ASML; some observers suggest that there may be up to three separate current efforts within China, involving private, state, and educational institutions other than SMEE, to develop and deliver a prototype Chinese EUV lithography scanner in the next few years.
The key driver in the development of advanced Chinese lithography equipment appears to be a government-backed effort to strengthen public-private collaboration in order to enhance innovation; in particular, the state seeks to overcome developmental bottlenecks by easing the transfer of advanced state-backed R&D to designated private-sector companies such as SMEE.
