  The report believes that the company's strategic positioning in front-end coating and developing core equipment in wafer manufacturing is crucial, as the global market has long been monopolized by overseas companies, with a relatively low domestic production rate. Under the trend of supply chain self-control, domestic wafer fabs are accelerating the introduction of domestically produced equipment. As one of the few domestic manufacturers capable of providing mass-produced front-end coating and developing machines, the company has consistently secured orders from leading wafer foundries since 2025. Multiple equipment models have demonstrated excellent performance in mass production verification, leading to continuously increasing customer recognition.

  The research report points out that leveraging the resources of the Naura Technology Group platform, the rapid expansion of downstream demand will drive simultaneous growth in the company's chemical cleaning and bonding equipment. Net profit attributable to the parent company is projected to reach 223 million, 388 million, and 677 million yuan in 2026, 2027, and 2028, respectively. The increased production volume of core equipment, coupled with a shift in gross profit margin, will be key drivers of the company's rapid performance growth.

Gallium core wafer-level thick-film epitaxial wafers pass device verification, outperforming imported products.​


Hangzhou Gallium Core Semiconductor Co., Ltd. has successfully completed a major milestone in semiconductor manufacturing, with its gallium oxide homoepitaxial wafers passing rigorous device verification. In collaboration with Xi'an University of Electronic Science and Technology, the company fabricated terminalless Schottky Barrier Diodes (SBD) using its thick-film epitaxial wafers, which feature a 10 μm epitaxial layer thickness and a carrier concentration of 1×10¹⁶ cm⁻³. The resulting devices demonstrate excellent breakdown voltage and conduction characteristics, with core parameters reaching international advanced levels. This achievement marks a crucial breakthrough for China's large-size gallium oxide materials, moving them from research to reliable device application while currently ensuring a stable stock supply for downstream R&D and mass production.

The performance data reveals that Gallium Core's technology significantly outperforms leading Japanese competitors in key metrics. In terms of voltage handling, the SBD devices exhibit a breakdown voltage range of 1090-1490 V, indicating a low defect density and high reliability suitable for ultra-high voltage applications. Additionally, the specific on-resistance ranges from 2.64.5 mΩ·cm², which is far lower than imported counterparts. This combination allows the devices to achieve an optimal balance between conduction efficiency (low energy loss) and blocking capability, solving a common trade-off in high-performance power semiconductors where improving one parameter often degrades the other.

This breakthrough underscores China's strategic approach to technological self-reliance rather than simply adopting international standards. Gallium Core Semiconductor employs a distinct "Chinese characteristics" path featuring a self-developed casting method that eliminates reliance on expensive iridium crucibles, thereby reducing material costs and enabling independent control over crystal growth thermal fields. By managing the defect density and doping uniformity more flexibly through this proprietary process, the company has achieved precise control over critical parameters such as layer thickness and carrier concentration.

Consequently, the superior performance of these devices validates the reliability of Gallium Core's large-scale thick-film epitaxial processes, effectively ending long-standing dependence on imported high-end gallium oxide materials for domestic use. The company now offers series-based layouts with customizable parameters including epitaxial layer thickness, carrier concentration, and doping type to flexibly meet the diverse requirements of both academic research and industrial mass production, positioning China as a significant player in wide-bandgap semiconductor innovation.

Flow physics and modeling in extreme ultraviolet sources​

Abstract​

The development of high-power extreme ultraviolet (EUV) light sources based on the laser-produced plasma (LPP) principle is crucial for advanced lithography, enabling the continued scaling of semiconductor devices. However, the underlying processes-involving laser-droplet interaction, plasma evolution, and debris transport-are governed by complex, multiscale, and multiphysics phenomena that pose significant challenges for both simulations and experiments. This review comprehensively surveys recent advances in the flow physics and modeling of LPP-EUV sources, focusing on three key areas: (1) numerical modeling and simulation of laser-tin droplet interaction, including laser absorption, radiation transport, equation of states, etc; (2) progress in understanding droplet dynamics under femtosecond to nanosecond laser pulses; and (3) the flow physics of debris transport and mitigation strategies such as buffer gas jets and magnetic fields. By integrating insights from simulations, experiments, and theoretical analyses, this review aims to bridge the gap between fundamental flow physics and applied EUV source engineering, providing a valuable reference for researchers working toward more efficient and debris-resistant EUV light sources.​

So there is a book called "Lithography Machine Software Architecture" that they tech kids in high school in China? Wow. Most people in school the closer they get in microelectronics is to program a microcontroller for some robot. And in University is a mask aligner or if you are lucky a e-beam machine in a microfabrication lab.

doesnt work? Added a new link above.
The book is targetting mainly for authur's province, southern Xinjiang. He was named after the kunlun mountain nearby. He figures the west only talk about forced labor and forced concentration camp. He wants shows the development of Xinjiang and his specialty will be added value to to advancement and education of the province.
No, it's not really meant for the rest of China. But feel free if other provinces want to use it.
Nah, micontroller is trivial here. The architecture discussed in book involved maybe hundred of FPGAs controlling thousands of hardwares. PCIe and EtherCat bus..talking about large scale integration needed for euv and duv.
