in case others don't get the joke. The second one is referring to the HEPS by Tsinghua

As for memory chips, i don't think it really matters whether or not YMTC is able to ramp up 232 layer production right now since they already have the technology. From what I hear, they aren't that far from domestic + ASML for it. Again, word from street. Take for what you will. Even if they can only expand 128-layer production next yr, the performance is fine based on reports others have done.

Bigger concern is with DRAMs. I would suggest that everyone keep their mouth shut about this, because Huawei will need to source a bunch from 3rd party here and use up its stash.

Well, it will be nice for CXMT to get to 1y node. It would be really nice if they can at least get de-americanized 1x working next yr. looks like AMEC at least have tools for everything now

The last heard, YMTC was pretty positive about the progress of qualifying domestic equipment. But their target completion date had been end of 2024, not sure if this means we can expect to pull in the completion target date or if it simply means we can meet the target. They are definitely more bullish on this front than CXMT on theirs.

progress update by Gerald Yiin of AMEC (that someone had shared on SDF) seemed to be consistent with what I heard from YMTC and CXMT.

I’m sure Huawei will figure it out. I think it’s difficult for Huawei, but it’s definitely not impossible.

we got to trust Huawei’s capability to resolve this.
I have the feeling that both DRAM and NAND chips Huawei stockpiled in significant numbers, not to mention just recently the entire sector was in a significant slowdown so it was very cheap to buy a lot of the chips.

I remember just a few years ago, Huawei had a lot of Kirin chips stockpiled just before the sanctions hit, and Huawei was able to sell phones and other consumer wearables for a 1 year+.

Maybe domestic alternatives will be good enough for Huawei when the stockpiled chips finish. I have the feeling that NAND will be for sure available, not sure about DRAM.

The CMOS also has the domestic Haowei ov648B.

I can’t imagine the sheer number of meetings they must have had as they designed, manufactured, and then started to market this thing.

I refuse to believe no one asked the question… wait what about the DRAM? I’m sure they have a fix for something this obvious, at least for the next 12 months.

Signing orders in double figures! Gaoche Technology helps domestic silicon carbide enter the 8-inch market!​


Recently, Gaoche Co., Ltd. has received new orders for its 8-inch silicon carbide diamond wire slicing machine. As of now, the company’s cumulative number of orders for its 8-inch silicon carbide diamond wire slicing machine has reached double figures! Basically covering the new 8-inch diamond wire slicing production capacity demand, leading the industry upgrading and transformation.

With the introduction of diamond wire cutting technology in the silicon carbide industry, the cost advantage of diamond wire cutting technology has gradually emerged, and the market penetration rate of diamond wire cutting technology has increased rapidly. Gaoche's 8-inch silicon carbide diamond wire slicing machine has been highly recognized by leading domestic silicon carbide substrate companies, and the company has received bulk orders.

Next, Gaoche will continue to leverage its joint research and development advantages of "cutting equipment, cutting consumables, and cutting processes" to achieve more technological breakthroughs, promote the process of localization substitution, and work with industry customers to help my country's semiconductor industry achieve higher-quality development .

this guy is good at following others account, but he doesn't have any personal sources.

From what I can see, Huawei already has the CMOS supply chain domesticated, but DRAM is clearly an issue here. Saying that CXMT has it figured out doesn't make it so
