Huawei and China Cell full discipline check of latest community answer

Huawei is repeatedly engaged on chipset printing applied sciences, and two latest patents present that analysis is making speedy progress. As well as, Huawei can also be engaged on new patents for lithographic ultraviolet mild.


Lithography is a very powerful step in chipset manufacturing. The explanation why chip know-how has been capable of evolve steadily from 100 microns to 3nm within the final 60 years is due to lithography. With out lithography, there is no such thing as a chipset manufacturing.

Subsequently, Huawei is engaged on new applied sciences for printing and manufacturing chipsets.

Let’s check out these patents.

First patent:

The patent was filed on Could 13, 2021, is now printed. The specs of this patent cowl applied sciences associated to ultraviolet mild.

Insights present {that a} lithography machine and machine management methodology are associated to the optical discipline and may clear up the issue of inhomogeneous coherent mild because of the formation of an interference sample everlasting.

The reflective floor of the reflector consists of many micro-reflective surfaces. Many micro-reflective surfaces embrace a primary micro-reflective floor and a second micro-reflective floor adjoining to the primary micro-reflective floor.

There’s a distinction in top Ah between the primary microreflecting floor and the second microreflecting floor, and the peak distinction Δh is within the vary (0, ka]the place is the wavelength of the polar mild. purple, whereas ok is a optimistic integer better than or equal to 1.

Second patent:

The second patent is titled “Mirror, photolithography machine and management methodology”. It has patent software quantity CN202110524685.X. ​This will clear up the issue that coherent mild can’t be uniform because of the formation of a hard and fast interference sample, which can also be a typical drawback in EUV lithography.

The patent reveals a lithographic machine, which makes the collected mild depth of the illuminant discipline uniform over the publicity time by repeatedly altering the interference sample shaped by the coherent mild.

It will assist the machine obtain the aim of uniform lighting. It additionally solves the issue in associated artwork that mild can’t be uniform as a result of the mixed mild types a hard and fast interference fringe.

It may be seen that Huawei has been working to resolve the issue of chip necks for lithographers as a result of that is an inevitable a part of breakthroughs in chipset improvement.

research on huawei chipset printing technology


Plainly Huawei is pushing itself to the restrict within the lithography discipline. In the meantime, lithography reveals that Huawei will make a breakthrough, together with different firms sooner or later.

Subsequently, it’s probably that Huawei will obtain 100% Chinese language chipset printers within the close to future.
