On November 1, 2024, Sidea Semiconductor Equipment (Shenzhen) Co., Ltd. (hereinafter referred to as Sidea) made new progress in its IPO on the Shenzhen Stock Exchange’s ChiNext board. The company has replaced its auditing firm and updated the relevant financial documentation.
Focus on Semiconductor Probe Testing Technology
According to the prospectus, Sidea was established in 2003, primarily engaged in the research, development, production, and sales of semiconductor-specific equipment. The company’s core probe station equipment is essential for semiconductor wafer testing and is also used in design validation and final product testing. This technology plays a critical role in evaluating chip performance and defects, ensuring test accuracy, and improving testing efficiency.

Sidea‘s probe stations are used by numerous optoelectronic chip manufacturers, catering to the equipment needs of the next-generation display technologies, such as Mini/Micro LED chips. Building on its experience in probe testing technology and semiconductor equipment, the company has also developed and mass-produced other semiconductor-specific equipment, including sorters, exposure machines, and AOI testing equipment.
Broad Application in Various Sectors
Currently, Sidea‘s probe station equipment serves multiple sectors, including integrated circuits, optoelectronic chips, discrete devices, and third-generation compound semiconductors. Its customers include prominent manufacturers such as Silicon Microelectronics, BYD Semiconductor, Yandong Microelectronics, Huachen Technology, Sanan Optoelectronics, Oplink Technology, and GoerTek, which are involved in wafer manufacturing, packaging, testing, optoelectronic devices, discrete components, and sensor production.
Financial Growth and Increasing Dependence on Probe Stations
From 2020 to 2022, Sidea‘s revenue grew from ¥184 million to ¥436 million. During this period, the proportion of revenue from chip probe stations increased from 60.17% to more than 70%. It is worth noting that Sidea‘s chip probe stations are suitable for automatic testing of optoelectronic chips like 4-6 inch PD, APD, and LED.
Customer Concentration and Market Strategy
Sidea has a relatively high customer concentration. Between 2020 and 2022, the sales from its top five customers accounted for 61.79%, 59.74%, and 77% of total revenue, respectively. Sanan Optoelectronics was the largest contributor, accounting for 51.85% of Sidea‘s sales in 2022.
Raising Funds to Strengthen R&D in Mini/Micro LED and Other Technologies
In this stock issuance, Sidea plans to raise ¥556 million to fund several key projects, including:
- Probe Station R&D and Industrial Base Construction – This will increase the company’s investment in semiconductor testing technology and enhance its R&D capabilities for probe station products. The project will also expand production capacity, overcoming capacity limitations and allowing for further business expansion.
- Sorter Technology R&D – Focused on the Mini/Micro LED market, this project will introduce advanced research software and hardware equipment to build laboratories for high-precision chip picking, high-volume sorting, and automation. It will also recruit top engineers to enhance R&D capabilities in these areas.
- Marketing Service Network Upgrade – This initiative will strengthen Sidea‘s marketing and service network, improving its customer service capacity and market expansion potential. It will also ensure the smooth absorption of new production capacity, laying the foundation for future business growth.
