Shandong Liguan Microelectronics Equipment: Accelerating the development of 12-inch liquid phase SiC crystal growth equipment​


Recently, Shandong Liguan has made significant achievements in the research and development of 12-inch silicon carbide (SiC) crystal growth furnaces. According to the company, it has successfully overcome the technical difficulties of the 12-inch physical vapor transport (PVT) resistance heating crystal growth furnace and successfully completed the delivery of the first two units of the equipment. At the same time, Shandong Liguan is stepping up research and development of 12-inch liquid phase SiC crystal growth equipment. With the key breakthrough in the commercialization of the 12-inch resistance crystal growth system, Shandong Liguan has formulated corresponding plans and is expected to achieve mass supply of 12-inch crystal growth equipment in 2025, and is committed to promoting domestic silicon carbide materials to occupy a leading position in the global supply chain and enter the first echelon.

Shandong Liguan has successfully developed an 8-inch PVT silicon carbide crystal growth furnace and has achieved mass sales. The crystal growth furnace integrates induction and resistance heating functions and is suitable for the growth of conductive and semi-insulating SiC crystals. Its innovative thermal field design improves temperature uniformity and stability by more than 30%, thereby significantly improving the yield and consistency of crystals to international mainstream standards. At the same time, the equipment is equipped with an automated control system that effectively reduces manual intervention and production costs, and has been selected by leading domestic and foreign customers.

According to public information, Shandong Liguan's product line covers a wide range of semiconductor material process equipment from the first to the fourth generation, and all of them have independent intellectual property rights, achieving complete independent control. These devices are widely used in the manufacturing of new electronic devices such as integrated circuits, power semiconductors, compound semiconductors, 5G chips, optical communications, and MEMS.

Is this Harmony OS PC? That would be an impressive score.

This is simply impossible. I mean we could discuss rumors but some sanity checks are needed first before posting these outrageous performance claims.

Some confirmed info shows a 4 big + 4 mid + 2 mid CPU topology on the HarmonyOS PC. The 4 big cores and 2 mids are the same ones from Kirin 9010 (Pura 70 Pro). The other 4 mids are improved ones over the 9010 mids. Given that the single core score on 9010 is around 1440 and the PC big cores are clocked at the same frequency, there would be at best 10% improvement on single core from larger caches, higher power envelope and improved memory bandwidth. My guess is around 1600 on single core. Multi-core is a bit difficult to predict, but given there are 10 cores, my guess is somewhere between Apple M1 and M2, which may be 9000.

So, 1600/9000 would be a much closer estimate. The scores in the screenshot are definitely made up and we should not have the wrong expectations.

That is why I put the question mark in my post.

Nevertheless the screenshot is taken from the geekbench official website:

Actually submitting a fake entry to the Geekbench database isn't too difficult. The device label (HAD-W32) can be changed fairly easily in Linux and Android.

Okay, I clicked your Geekbench link and checked the details. This is likely a Linux virtual machine running on an Apple device. They mocked up the device label but forgot to hide the CPU implementer. ARM implementer 97 (0x61 in hexadecimal) is Apple for sure. This is an Apple device. Judging by the scores it's likely the latest Apple M4 Macbook.
