Did the article say "domestic" or do other articles confirm that this is a domestic line? The English translation (via Google) did not mention domestic.

An Effective Hybrid Rescheduling Method for Wafer Chip Precision Packaging Workshops in Complex Manufacturing Environments.
Abstract
With the continuous development of semiconductor manufacturing technology and information technology, the sizes of wafer chips are becoming smaller and the variety is increasing, which has put forward high requirements for wafer chip precision manufacturing and packaging workshops. On the one hand, the market demand for multiple varieties and small batches will increase the difficulty of scheduling. On the other hand, the complex manufacturing environment brings various types of dynamic events that will disrupt production plans. Accordingly, this work researches the wafer chip precision packaging workshop rescheduling problem under events of machine breakdown, emergency order inserting and original order modification. Firstly, the mathematical model for the addressed problem is established, and the rolling horizon technology is adopted to deal with multiple dynamic events. Then, a hybrid algorithm combining an improved firefly optimization framework and variable neighborhood search strategy is proposed. The population evolution mechanism is designed based on the location-updating law of fireflies in nature. The variable neighborhood search is applied for avoiding local optima and sufficiently exploring in the neighborhood. At last, the test results of comparative experiments and engineering cases indicate that the proposed method is effective and stable and is superior to the current advanced algorithms.
He is well known for domestic lines
Yes, I think it's pretty well known that Yandong phase 1 was using dry scanner from SMEE, so it would make sense for them to use Arfi scanner for 55-28nm
The number he provided based on TechInsight calculation makes sense. N+2 matches what hvpc showed to me back in early 2024. N+3 being a 20-25% improvement in transistor density seems reasonable. They got a 10% shrink on both side.
He seems to be giving a different transistor density based on his own calculation also. Which is whatever, who cares. Using his number, N+3 is basically half way between N7 and N5.
North China Electronics Constructs a Talent Hub for the Industry.
Beijing Naura Microelectronics Equipment Co., Ltd., a subsidiary of Naura Technology Group (002371.SZ), is a key player in China’s semiconductor equipment industry with over 70 years of industrial heritage.
