Now, they better stock up those CPUs while they still can. It should've been obvious when this was first announced that this is coming.

I agree, more than Qualcomm, it is Intel and AMD that are critical to Huawei.

Huawei is already almost out of the phone business, eventually they will exit altogether, today this is not a big difference, we are not in 2019 anymore. Instead without Intel and AMD, Huawei has to give up the very remunerative and much more strategic cloud business. In the worst case they will fallback to be a full software company in the computing world, like it is Microsoft. But of course they will keep the communication business that is their core business and their key asset.

Instead, I am more worried when US administration will ban Intel and AMD chips for all the Chinese companies....that will hurt.

Maybe now it seems impossible, but within a year, if relations continue to worsen (and especially if China continues to grow), with US 2024 presidential campaign in full swing, I'd definitely not rule out this possibility.

His advice to Chinese scientists is that they tackle problems of making 90nm or 130nm chips before focusing on more advanced 28nm ones.

...and I advice him to find a new job.

He currently sells US semi equipment in China for a living. Doomsaying is part of his selling arguments....but the most dire and negative predictions I can foresee are about his job.

Big news, CETC 46th Institute has now prepared China's first 6-inch Gallium Oxide wafer

There are wide applications in both military and commercial fields, but I'd imagine military usage is more applicable right now. It would most likely allow for more powerful radar than the current GaN AESA radar. It could also be used in other applications that require operating under high temperature and voltage environment.

All this is interesting because GaN itself is still just getting to the mass commercialization stage even though it's been used in military radar for a while now.

We are just getting to the point where fabs are producing GaN wafers and such.

And now we have Ga2O3.

It's pretty amazing how fast they've moved here
浙大杭州科创中心也于2022年5月成功制备直径2英寸(50.8mm)的氧化镓晶圆,而使用这种具有完全自主知识产权技术生长的2英寸氧化镓晶圆在国际尚属首次。
so Hangzhou Science and Technology Innovation Center of Zhejiang University just succeeded in 2-inch wafer in May
北京铭镓半导体于2022年12月完成4英寸氧化镓晶圆衬底技术突破,成为国内首个掌握第四代半导体氧化镓材料4英寸(001)相单晶衬底生长技术的产业化公司。
Beijing Mingga Semiconductor became the industrial company to master 4-inch wafer in December.

And now we get to February and they have now created a thermal field structure capable of growing 6-inch Gallium Oxide crystal substrates.

At this rate, we are going to have industries producing it by the end of this year and moving on to 8-inch wafers.

Interesting to see so many heavy weights involved here including SIOM.

How much pull does China have in this field given they control the gallium production in the world. I think they make like 90%+ of it

In December U.S.-listed chipmaker Magnachip Semiconductor Corp
Please, Log in or Register to view URLs content!
announced it would terminate a $1.4 billion buyout plan from Chinese private equity firm Wise Road Capital following a probe into the deal from Washington's Committee on Foreign Investment in the United States (CFIUS).
Chipmaker Magnachip is planning to suspend production at its factory in Gumi, South Korea for a week starting on Saturday.

This is unprecedented for a chipmaker as fabs are usually run 24/7 for the full year.

Sources said Magnachip was doing so from its high inventory and low demand.

Power will still be on at the fab but staff will take a break from work, they said.

Magnachip specializes in display driver IC and power management IC production.

It only designs driver ICs while it manufactures its own power management IC such as power discrete at its fab in Gumi.

The fab at Gumi has a capacity of 40,000 wafers per month and uses 8-inch wafers.

It is extremely rare for fabs to stop production and most of them are caused by unintended accidents.

Two years ago, Samsung suffered a power outage at its fab in Austin. This caused production to stop for three days and it took a month for the tech giant to restart production.

Last year, Magnachip recorded US$337 million in revenue and US$5.24 million in operating loss. It turned red in turns of profit while revenue dipped by 28.8% from 2021.

Meanwhile, most chipmakers that run 8-inch foundries are seeing their operation drop due to the downturn in the chip sector.

Actually. the best semiconductor is probably cubic boron arsenide. Hope China is working on this next generation material.

I don't know about that. It doesn't have a stable native oxide I think, that was the big problem with GaAs - can't build insulator or etch stop films by simply introducing oxygen or water, you have to deposit something, and deposition might not be so easy to remove. The native oxide of Si and SiGe is what makes them super convenient as semiconductor.

BAs might be good, but only in niche applications like power or RF. Not logic.

Q&A from Kingsemi recently I think, not 100% sure
Q:2022年订单的执行情况

确认为今年收入问题不大,今年还是可以保持50%以上收入增长。今年全球晶圆厂设备支出会下降,但对于国内尤其是我们所处的涂胶显影行业,签单还是可以维持50%以上增长。

Q:签单情况

今年逻辑和储存客户都在和我们对接,今年武汉储存厂商也会下机台,晋华今年至少是有10台左右的订单,如果全下到今年会有十几台。整体来看,我们跟的前道的客户,签单还是可以比去年增长50%以上。

Q:验证的项目是SRD,三代机验证情况如何?

浸没式三代机已经通过验证,今年预计签单也会比较理想,我们判断今年新签的里面浸没式会占30%。
going to be real noob of me, but what is SRD?
Q:中芯国际公司之前浸没式没有送样,现在怎么样?

中芯国际目前单子还没有签下来,我们商务在对接,我们当然希望把浸没式导入做评估。

Q:福建晋华

现在还在谈,估计上半年不会签订,1月份我们签了1台,其他的可能要等到下半年。

Q:存储器客户

三大客户福建晋华,长江存储和合肥长鑫都要关注,合肥长鑫量也不小但目前我们只看到一个饼,什么时候落下来我们也会接洽。

Q:福建晋华的扩产量级

2万片

Q:长江存储

今年会是国产导入验证的大量,但不是量产大年。

Q:SRD浸没式验证完以后,是不是公司工艺覆盖度就完全解决了?

是的

Q:后道方面,订单如何预期?

目前没有看到明显恢复迹象,所以我们对后道策略还是维持和去年同样的签单水平就可以了。
Looks like they are pretty involved in qualifying for memory chip customers Fujian Jinhua, YMTC & CXMT.
Fujian Jinhua will increase production by 20k wpm
YMTC will mostly just be validating domestic tools this year, no production increase
Looks like they are hoping to sign something with SMIC but hasn't gotten any orders. Hoping to get immersion process orders.
Looks like Jinhua is a major customer for them.
