The present invention relates to the field of semiconductor material technology, and in particular to a sealant for electrostatic chuck gaps, and a preparation method and application thereof. The main raw material of the sealant is organic silicon, and it may also include modified nano-silicon dioxide and other fillers. The present invention has a convenient operation process and a wide range of applications, and is applicable to gaps of any shape as long as the thickness is less than 2 mm. At the same time, the corrosion resistance of the sealant is more excellent, which reduces the maintenance cost of the electrostatic chuck and prolongs its service life.

After the transformation to Fab-Lite, GigaDevice's high-pixel CMOS image sensors enter a new stage​


As a leading CIS supplier in China, GigaDevice has successfully transformed into a Fab-Lite model. After the Shanghai Lingang factory was put into operation, it set a new goal of revenue exceeding US$3 billion. Entering the high-end CIS market is an important part of achieving this goal.

In the past year, GigaDevice has continuously updated and iterated, and has launched high-pixel products such as GC50E0, GC50B2, and GC50E1. According to the latest news, GigaDevice has recently achieved the research and development of 50-megapixel products with 0.61μm small pixels on its own production line, and has passed customer certification, and is expected to achieve mass production soon. Today, in the fierce CIS competition landscape, GigaDevice, which was the first to transform into Fab-Lite, is gradually entering the high-end market, breaking the growth ceiling, and accelerating the localization process of high-end CIS.​

The construction and commissioning of GigaDevice's Lingang factory is an important milestone in its transformation and development. The project announced the first batch of mass production in June 2023. The factory mainly focuses on the research and development and industrialization of 12-inch CIS integrated circuit feature processes, supporting GigaDevice to break through and iterate in the field of high-end image sensors.

The Fab-Lite model is between Fabless and IDM (vertically integrated manufacturing). By combining self-built factories with outsourced processing, it not only retains the flexibility of the Fabless model but also enhances independent production capabilities. By building some of its own production lines, GigaDevice has achieved independent control over key manufacturing links, which also provides support for its layout in the high-end market.

Practices over the past two years have proven that under the Fab-Lite model, GigaDevice's R&D results are accelerating industrialization. In the past year, GigaDevice has rapidly launched a number of high-pixel single-chip products, including GC32E2, GC50E0, GC50E1, GC50B2, GC50F6, etc., continuously expanding the mid-to-high-end market and becoming an important development support for breaking the growth ceiling of enterprises.

I'm not sure why this is, but this is grim news. China has been overtaken by America, which is determined to suppress it, as the world's largest semiconductor market. Nystedt says it's because of huge AI related spending, but the chart shows the U.S. market started to grow faster than the Chinese market even before ChatGPT. Combined with other data showing that U.S. total compute has been growing faster than China's since 2021, and China may be gradually losing the semiconductor competition if this continues.

Edit: In terms of industry sales, it's even worse. The U.S. industry has 50% of global semiconductor sales, and China only had 4.5%, down from 7.2% last year. The last time U.S. semiconductor industry wasn't #1 in sales was the late 1980s and early 1990s, when Japan briefly had more than half the global market. Last years info here:

For start the SIA mostly cover chips as its name implies made by US companies or companies with sales in the US. As China made more of their own semiconductors they buy less from US companies and I don't think SIA take into account Huawei GPUs in their statistics and Naura PECVD machines. In fact I think is bad news for US companies because they are losing market share in China while Chinese companies are gaining in the own country.

Another thing is that this is mostly datacenters with extremely expensive GPUs and AI hardware. Is not like the US is manufacturing more EVs, smartphones, TVs or upgrading their 5G networks.

In fact SiC manufacturer wolfspeed just declared bankruptcy I think they couldn't adapt fast enough when Chinese companies ramp up their production and reduced prices of SiC modules.

And there lies the danger sales vs volume. Company A is first in the market and is selling automotive SiC modules at 1500 dollars. Company B is bit later at the time but has catch up and start selling SiC modules at 500 dollars. On Paper at first company A has larger revenue but company B is selling more volume and gaining more clients than company A even if company B revenue seems lowers. By time magic of being the first fade away if company A has not find ways to make the products competitive they are in big trouble.

Yes, according to SIA, the USA didn't just take over the lead from China. China is reduced to a pigmy market of 4.5%!!! LOLIMG_5852.png

Yes, and let us extrapolate this further.

The vast majority of chips consumed in the US by dollar amount is in AI. The most important items in this sector are the NVIDIA chips.

In the AI race, China and the US are neck and neck BUT the US has direct access to NVDA while China does not.

So the rarity of NVDA in China should push chips like A100 and H100 to astronomical prices there. And it did in the years immediately following Biden's ban.

But beginning in the third quarter of 2024:

Smaller Chinese cloud providers charge around $6 an hour for a server with eight A100 Nvidia chips. Compared to similar US vendors, with an hourly rate of $10, advanced Nvidia chips are not difficult to come by in China.

However, larger Chinese cloud operators, like Alibaba, must ensure compliance with US export regulations and charge $12-$18 an hour for server rentals. Still, their prices are lower than comparable US servers, which charge between $15 and $32 an hour. Chinese companies can also rent Nvidia processors online from US-based companies like Microsoft and Amazon.


So NVDA chips in China had crashed while China has expanded AI in the commercial sectors even more than the US.

Apr 3, 2025 — Research by McKinsey, a consultancy, suggests that 19% of Chinese people use AI at work, whereas 12% of North Americans do.

Considering that there are four times more Chinese than Americans, it is much than a mere 7% advantage in favor of China in overall adoption and use of AI.

So we have more adoption of AI but a huge (and continuing) drop in the price of the foremost AI chips and those which are banned to China and which SHOULD be astronomically expensive.

Sorry but one cannot help but find it immensely optimistic to anyone following both semicon and AI development in China with these implications:

1) domestic chips are of such quality and quantity that the fast growing Chinese AI community is basically ignoring NVDA chips (painstakingly smuggled in or patched to overseas DCs), and using obstensibly local ones,

2) AI compute in China -- despite the US embargo -- has become so inexpensive that the smaller developers are finding it more affordable to use NVDA chips(!?!) from small Chinese providers than using the large ones who are increasingly building out Ascend clusters,

3) Couple with the DeepSeek sea-change where pure software logic can provide results comparable to American companies using brute force compute and you have an environment set up in China where the bar to entry for AI is far lower and allows a far wider breadth of adoption they could ever do in the US no matter how much NVDA makes every year.

There will be a tsunami of unimaginable proportion coming out of China on AI. It will be a sea of affordable Chinese AI chips, models and practices flooding acrossing the world. Just like with cars, US AI will be a island protected by sky-high prices only Americans and few select other Westerners will pay for.
