Huawei and China Cell have accomplished area analysis of recent networks

Huawei continues to analysis the mind printing know-how and the earlier knowledge. – these two experiences present that the analysis is progressing quickly. Along with this, Huawei can be investigating new patents for ultra-violet mild lithography machines.


Lithography know-how is crucial step in chipset manufacturing. The explanation why chip know-how has been in a position to progressively enhance from 100 microns to 3nm within the final 60 years is due to lithography units. With out a lithography machine, there is no such thing as a chipset business.

Subsequently, Huawei is researching new applied sciences for printing and manufacturing.

Let’s check out these patents.

First patent:

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

Particulars present the lithography system, and its management technique, which is expounded to the optical area and may remedy the issue that the sunshine can’t be adjusted because of the presence of a set interference sample.

The reflective floor of the mirror contains quite a lot of reflective surfaces. The plurality of reflective surfaces embrace a primary reflective floor and a second micro-reflecting floor close to the primary micro-reflecting floor.

There’s a top distinction Ah between the primary micro-reflecting floor and the second micro-reflecting floor, and a top distinction Δh Positioned within the interval of (0, ka]the place λ is the size of the ultraviolet mild, whereas ok is a a constructive quantity better than or equal to 1.

Quantity two:

The second patent is entitled “Mirror, Photolithography Equipment and Management Methodology”. It has a patent utility variety of CN202110524685.X. This could remedy the issue of not with the ability to regulate the uniform mild because of the formation of a set interference sample, which can be a standard downside in EUV lithography.

The proof exhibits the lithography system, which makes the sunshine assortment of the sunshine area to be correct through the publicity time by constantly altering the interference sample produced by the coherent mild.

This would be the system to attain the purpose of the identical mild. It additionally solves the issue in associated applied sciences that the sunshine can’t be uniform as a result of the sunshine supply produces a set interference sample.

It may be famous that Huawei is researching to resolve the issue of chip bottleneck for lithography machines as a result of it is a vital a part of the chipset improvement.

Huawei chipset printing technology


It appears that evidently Huawei is pushing itself to the restrict within the area of lithography units. At present, lithography know-how exhibits that Huawei will succeed, together with different firms sooner or later.

Subsequently, it’s doable that Huawei will be capable to obtain a 100% Chinese language chipset within the close to future.
