Shangyuan Zhixing completes nearly 100 million yuan Series A financing to accelerate the construction of its autonomous driving ecosystem.​

On October 31st, Shangyuan Zhixing completed a Series A financing round of nearly 100 million yuan, led by Furong Investment with participation from Xichuang Capital. The funds will be used to advance the generational upgrade of its intelligent skateboard chassis and build an open, full-stack autonomous driving ecosystem platform, accelerating its next phase of growth.

As a leader in intelligent skateboard chassis technology, Shangyuan Zhixing has become a key partner for major autonomous vehicle companies due to its drive-by-wire core components and end-to-end autonomous solutions. The company is now transitioning from being a "core technology foundation" to a "full-stack scenario empowerment platform," enabling rapid deployment of L4 autonomy across industries.


Founder and CEO Feng Shu emphasizes that the next decade in autonomous driving will belong to scenario operators—those with rich, closed-loop real-world use cases. To meet this demand, Shangyuan Zhixing is launching a range of Class I–III chassis modules, allowing customers to "build vehicles with one click," enabling algorithm teams to focus on software and operational partners to scale efficiently.

The company has already delivered over 7,000 intelligent chassis and achieved more than 35 million kilometers of L4 autonomous driving mileage, solidifying its position as a leader in the field.

Wang Guodong from Xi'an Venture Capital highlights that unmanned urban logistics is a fast-growing segment in low-speed L4 autonomy, where Shangyuan Zhixing's "ultimate performance + ultimate delivery" model has established it as a de facto benchmark. He praises the team’s strong strategy and engineering execution.

With its end-to-end capabilities, Shangyuan Intelligent Mobility is positioned to act as a foundational force in scaling L4 autonomous driving from pilot projects to full-domain real-world applications—driving industry-wide leapfrog development.

China Resources Microelectronics' fourth-generation silicon carbide MOS main drive module has been mass-produced and installed in vehicles.​

Recently, the SiC main drive module segment of China Resources Microelectronics Power Devices Business Group (hereinafter referred to as PDBG) has made another important progress. The fourth-generation SiC MOS main drive module independently developed by PDBG has been successfully introduced to a leading car company and has been put into mass production.

PDBG is a business unit under China Resources Microelectronics, responsible for the design, R&D, manufacturing, sales, and service of power devices. It comprises low-to-medium voltage MOSFET product lines, high-voltage MOSFET product lines, IGBT product lines, special device product lines, module product lines, and an automotive electronics division. It owns two independent power device brands: CRMICRO and Huajing.

According to CR Microelectronics, this type of module is based on the PDBG 1200V SiC MOS G4 platform chip, adopts ValueDual packaging, 6/8 transistors in parallel design, and has a minimum on-resistance of 1.6mΩ. It combines the low loss and high temperature resistance of SiC devices with the high system compatibility and high system efficiency of ValueDual modules, and performs excellently in commercial vehicle main drive system applications.

The ValueDual modules, already deployed in batches, utilize the 1200V 13mΩ chip from PDBG's independently developed fourth-generation SiC MOS platform. While maintaining the excellent gate characteristics of the second-generation platform, this platform further optimizes key parameters such as RSP, junction capacitance, and leakage current through design and process innovation, significantly improving power density and operating efficiency. This provides a series of more energy-efficient products for high-power-density, high-integration applications such as on-board chargers (OBC), main drives, and high-voltage direct current transmission (HVDC).

Norbornene and Epoxide-Substituted Silsesquioxane Photoresists with High-Sensitivity and Stability.​

​

Abstract​

The evolution of photoresists has been accelerated by escalating demands for pattern fidelity, particularly with the breakthrough of extreme ultraviolet (EUV) lithography in achieving sub-20 nm resolution. Herein, we report two kinds of partially alkyl-substituted silsesquioxane (PASS) resists to overcome the dual challenges of hydrogen silsesquioxane (HSQ) in EUV applications: inherent instability and unsatisfactory sensitivity. Through strategic integration with a photoacid generator (PAG), the optimized formulation demonstrates exceptional lithographic performance, achieving 14 nm resolution (line edge roughness of 1.3 nm) with a sensitivity of 4.3 μC/cm2 and a contrast of 5.1 under electron beam lithography. Besides, the PASS resist exhibits a 360-day gelation period and a 160-fold improvement over conventional HSQ. Systematic investigations combining micro-Raman spectroscopy and model compound studies reveal that PAG enhances both sensitivity and shelf stability through dual mechanisms: (1) a photoacid-catalyzed cross-linking reaction between siloxanes and (2) nucleophilic attack inhibition at silicon centers. These advances, coupled with successful electron-beam and ultraviolet patterning demonstrations and structural tunability, establish PASS resists as viable candidates for EUV lithography in semiconductor nanofabrication.

Leadway Technology: 6-axis automotive-grade MEMS IMU chip passes AEC-Q100 reliability test​

MEMS Consulting has learned that the self-developed 6-axis automotive-grade MEMS IMU GST80 by Daoyuan Technology has recently passed the AEC-Q100 reliability test .

According to the "Reliability Test Report" issued by the Integrated Circuit Chip Application Verification Platform of the Ministry of Industry and Information Technology, a total of nearly 30 batches and more than 3,000 GST80 chips passed all 24 tests , including high temperature storage/working life, solderability, electrostatic discharge human body model and electrostatic discharge charging device model, mechanical shock, and chip shearing, with zero failures .

Passing the AEC-Q100 test means that automotive chips have reached international authoritative automotive-grade standards in terms of reliability, environmental adaptability, and lifespan, and are a key passport to enter the automotive supply chain .

Previously, the GST80 inertial sensor chip received an independent and controllable evaluation report issued by the Fifth Research Institute of the Ministry of Industry and Information Technology , confirming that it meets the requirements for independent controllability. This also signifies that Daoyuan Technology has established a complete MEMS IMU full-stack R&D system and has a controllable supply chain.

First automotive-grade six-axis programmable IMU

The GST80 has a built-in dedicated floating-point accelerator that can estimate and eliminate various errors throughout the sensor's entire lifespan in real time, and supports user-defined custom functions, enabling edge intelligence at the sensing node. The SCON (Safety Controller) monitors all internal power supplies, clocks, hardware and software functions, and critical signals in real time, enabling immediate prediction and diagnosis of potential faults, truly achieving safety on the basis of reliability.
