China’s first photonic chip production line to be ready in 2023: media report

China's first production line for "multi-material and cross-size" photonic chips, or integrated optical circuits, will be completed in Beijing in 2023, a development that's expected to fill a gap in the nation's top-level manufacturing, the Beijing Daily reported on Tuesday.

Compared with electronic chips, photonic chips offer higher speeds and lower power consumption. The calculation speed and transmission rate are 1,000 times those of electronic chips, according to the newspaper.

If all goes as planned with the facility, it will show that the preliminary experimental research and development process is in place, with production technology that leads the world, analysts said.

According to the Beijing Daily, the production line will be built by Sintone, a Beijing-based high-tech enterprise.

The facility can meet market demand in multiple fields including communications, data centers, medical testing and other sectors, said the report, citing Sui Jun, the president of Sintone.

The domestic use of photonic chips has extended into scenarios in industry, consumer electronics, vehicles, defense and other fields, according to a report by Minsheng Securities in September.

The new facility will fill the gap in the field of photonic chip foundries in China and accelerate the process of domestic photonic chip replacement, Sui said.

Photonic chips will be the next major direction of chip development due to their stability and low power consumption, Xiang Ligang, an independent technology analyst, told the Global Times on Tuesday.

Such chips aren't yet being produced on a large scale anywhere in the world, so the new facility will show that China is leading in this technology in the world, said Xiang.

China has become the world's largest optical communication market, and the size of the domestic photonic chip market has expanded remarkably. From 2015 to 2021, the domestic photonic chip market expanded from $800 million to $2.08 billion, with an average annual compound growth rate of more than 15 percent, according to Insight and Info.

Sui said that making photonic chips is not as demanding as electronic chips in terms of structural requirements, as photonic chips don't require extremely high-end lithography machines such as extreme ultraviolet lithography, and can be produced using raw materials and types of equipment that are already mature in China.

Xiang stressed that it will take time and industrial verification from the beginning of construction to mass production after the facility is completed.

Sui said that the current development of the sector in China is more advanced in terms of applications and design but relatively weak in such basic aspects as equipment and manufacturing. The company will use its scientific achievements to provide practical and reliable support for core sectors such as quantum computing.
Can these be used as effectively to run 5G or better telecommunications base stations as presently used electronic chips can?

WASHINGTON, D.C. – U.S. Senator Marsha Blackburn (R-Tenn.), along with Senators Tom Cotton (R-Ark.), Bill Hagerty (R-Tenn.), Ted Cruz (R-Texas), and Marco Rubio (R-Fla.) sent a letter to President Biden demanding he act quickly to prevent Huawei from building the Pengxinwei IC Manufacturing Company (PXW) semiconductor plant. The opening of this plant would put the United States at a disadvantage in countering Huawei, advance Communist China’s Military-Civil Fusion campaign, put American semiconductor companies at a disadvantage, and pose a national security concern.

Will the plant use all Chinese equipment or some US tech as well? If all Chinese equipment then who the fuck do the tossers think they're, other than tossers.

Optical chips are not suitable for being logic chips with existing technologies. But they are very good for applications involving optical-data transmission. For example, their use as multiplexer and demultiplexer circuits for fiber-optic systems is very common. As far as I know there are benefits in using optical processes for some signal processing tasks in optical systems too.
Reading this it doesn't seems optical chips are that programmable like logic and FPGA chips?
It sounds like they will act more like specialised signal processing ASIC chips which isn't a bad thing.

If Huawei can save on power usage and heat production by replacing 5g signal processing components with optical components they might win back some battery time and cooling space in their high end consumer products, the powered usage and heat production can then be used for their 14nm~7nm logic chips. Where they will be using more power and producing more heat compared to say a 5nm qualcomm or apple chip.

LOL, if they haven't acted yet is because nothing from the US is going to that fab.

Interesting numbers. To which period they refer? Today?

Regarding etching, we can see that YMTC has 100 localized machines, and this represent the 21,9% of total etching equipment. So YMTC has in total 456 etching machines.

It is not a surprise that the vast majority of equipment is of foreign origin, because it is only recently that local manufactures have started selling in volumes to their customers. I'm sure if we consider only etching equipment sold in the last 2 years, the percentage of local suppliers is much higher.

Interesting the 74 pieces of equipment that google translated as degumming (the first entry in vertical list) but maybe is more correct to say wet photoresist removal (please correct me if I am wrong). This is a whopping 86% of total degumming machines. Somone knows who is the local manufacturer? I'd guess maybe is ACM Research or Kingsemi.
Kingsemi.
