Complete chain of manufacturing capabilities
Chip design
The chip design determines the structure and performance of the device and is a critical starting point for the entire manufacturing process. The core trunk focuses on power conversion and circuit control in high-voltage and high-current scenarios, and provides diversified design solutions based on SiC MOSFETs and GaN HEMTs. SiC devices are suitable for medium and high voltage such as 1200V/1700V and medium and high-power scenarios of 2kW~1MW, while GaN devices are more suitable for improving frequency and power density in small and medium-power applications. The core trunk is optimized to achieve high performance, low loss and cost control of the device.
Wafer fabrication
From material epitaxy and growth to wafer processing and CP testing, the core trunk line cooperates with high-quality foundries to formulate customized tape-out solutions to effectively control the manufacturing process, improve device performance, and shorten the product development cycle. Especially in the field of SiC and GaN, we have overcome key process problems such as epitaxial preparation and trench etching.
Packaging and testing
The packaging process not only needs to protect the chip, but also needs to take into account the heat dissipation performance and parasitic parameter control. The core trunk line cooperates with leading domestic packaging and testing factories to ensure the quality and reliability of device shipments, and finally verifies whether the products meet the design and customer standards through systematic testing.
Future directions
Technological innovation: Continue to deepen the third-generation semiconductor technology and develop more efficient and environmentally friendly power devices.
Market expansion: Lay out emerging application scenarios such as smart home and industrial automation to broaden product boundaries.
Collaborative cooperation: Strengthen technical and market cooperation with domestic and foreign enterprises to promote the coordinated development of the industrial chain.
