bro how can acquisition of Xinyuanwei (KingSemi) help NAURA to enter in Litho sector ??
Coating and Developing photoresist is a critical part of the lithography patterning process and they already have etching tools, remain to be seen if they would acquire companies for metrology tools like overlay metrology, OCD and CDSEM <like ASML has>, Computational Lithography Software or make it on their own. That would only left lithography machines from the patterning chain.

I wouldn't be surprised if they get into lithography, maybe not as advanced like EUV. But ArF, KrF and even immersion I don't think is out of reach for a company like Naura. China domestic lithography suppliers are already mass producing parts, components and sub-systems for lithography machines, remain to be seen if they are exclusive to SMEE or they could sell to other companies. But even then there other companies not part of the original project 02 that are entering the lithography supply chain in China and Naura can make their parts and subsystems.

I am speculating but looks they are pretty interested in lithography.

NAURA applies for patents on pulse power supply communication control method and related devices to improve the noise resistance of pulse power supply​


According to a report in the financial sector on April 24, 2025, information from the National Intellectual Property Administration showed that Beijing North Huachuang Microelectronics Equipment Co., Ltd. applied for a patent called "A communication control method and related device for a pulse power supply", publication number CN119813759A, and the application date was November 2024.

The patent abstract shows that the embodiment of this specification provides a communication control method for a pulse power supply. Through the controller of the pulse power supply, the noise signal induced by the target pin of the analog-to-digital converter and the interrupt information of the control module are monitored, noise information is obtained based on the monitored noise signal, and the noise level is obtained based on the noise information and the interrupt information. Finally, based on the noise level, the communication parameters of the control module are configured, thereby achieving the purpose of configuring corresponding communication parameters at different noise levels, so that the control module can communicate with other hardware modules based on different communication parameters at different noise levels, and realizes adaptive adjustment of communication parameters with noise level, which is conducive to ensuring the normal communication of the communication module with other hardware modules in different noise environments, and reducing the probability of abnormal working state of the pulse power supply due to communication abnormality in a strong noise environment, thereby improving the noise resistance of the pulse power supply.​

Wanye Enterprises achieved breakthroughs in materials and equipment in its annual report and first quarter report, with revenue in the first quarter increasing substantially by nearly double​


Wanye Enterprise released its 2024 annual report and the first quarter report of 2025. The report shows that in 2024, the company achieved operating income of 581 million yuan and realized a net profit of 108 million yuan attributable to the parent company. In the first quarter of 2025, the company's operating performance continued to improve, with operating income increasing to 193 million yuan, a year-on-year increase of 94.09%, a significant leap. Among them, the total revenue of equipment and materials business accounted for about 75%, becoming the core driving force for performance growth. It is worth noting that in 2024, the company successfully won orders for integrated circuit equipment of about 240 million yuan, demonstrating its market competitive advantage; in the first quarter of 2025, the bismuth material business was promoted in an orderly manner, with a net profit margin of over 20%, further deepening the strategic layout in the field of key semiconductor equipment and materials, and continuing to consolidate its position in the industry.​

Kaishitong leads the domestic ion implantation machine market with orders increasing in volume, laying a solid foundation for growth

In the field of semiconductor equipment, the company insists on driving technological upgrades with high R&D investment. In 2024, the company's R&D investment was 184 million yuan, a year-on-year increase of 13.14%, achieving sustained and stable growth in R&D investment over the years. With the wave of localization of semiconductor equipment, Kaishitong has ushered in an accelerated period of industrialization. In 2024, Kaishitong continued to obtain batch repeat orders from 3 leading customers, and added orders from 2 new customers. As of the end of 2024, Kaishitong's low-energy, large-beam ion implanter customers have exceeded 11, the number of ultra-low temperature ion implanter customers has exceeded 7, and the number of high-energy ion implanter customers has exceeded 2. From 2020 to the present, Kaishitong has received a total of more than 1.4 billion yuan in equipment orders, and 60 orders for 12-inch ion implanters. Last year, the expansion of its R&D and manufacturing base in Jinqiao, Pudong, Shanghai was completed, forming an annual production capacity of more than 100 ion implanters, supporting the evaluation of a full range of products and rapid customer introduction. At the same time, the company is preparing to build a testing center, which is expected to shorten the research and development cycle of new equipment, accelerate the independent control of complete machines and key components, and enhance the resilience of the supply chain.

Lead Technology empowers the industry chain to collaboratively build a closed-loop semiconductor ecosystem

In November 2024, Pioneer Technology Group, a global leading material technology company and leader in dispersed metals, officially became the new actual controller of Wanye Enterprise, injecting scarce resources and industrial synergy potential into Wanye Enterprise, and accelerating the completion of the creation of a comprehensive platform for semiconductor equipment and materials. Relying on Pioneer Technology's global supply chain advantages in strategic materials, the company quickly entered the field of semiconductor materials and fully developed bismuth metal deep processing and compound product business through its wholly-owned subsidiary Anhui Wandao Electronic Technology Co., Ltd. According to public information, bismuth materials can not only be used in the manufacturing of key products such as varistors and ceramic capacitors, but bismuth-based materials are expected to achieve extremely low resistance, approaching the quantum limit, and may effectively promote the semiconductor process to the next technical node. Since the first quarter of this year, the company's newly expanded bismuth material business has been advancing in an orderly manner, achieving operating income of more than 80 million yuan, net profit of 22.17 million yuan, and net profit margin exceeding 20%, laying a solid foundation for the company's continued deep cultivation in the field of semiconductor materials.

In addition, in terms of upgrading the supply chain, Pioneer Technology has complete semiconductor process service capabilities from high-purity materials-substrates-epitaxial-chips-resource recovery. It can not only provide supply chain support for electronic materials (such as doping materials, precursors, electronic special gases), key components (such as electrostatic chucks, flow meters), and ion source process testing for Kaisitong, a subsidiary of Wanye Enterprise, but also help Kaisitong achieve in-situ detection of machines, which helps to optimize and improve the overall performance of the equipment, and can create a resilient and diversified supply chain system for the ion implantation machine business.
