On July 24, the listing status for three companies seeking an IPO on the Shanghai Stock Exchange's Science and Technology Innovation Board (STAR Market) changed to "inquiry phase." These companies are Mifei Technology, Xiahe Technology, and Silang Technology.

Mifei Technology, with Guotai Junan Securities as its sponsor, plans to raise 1.191 billion yuan. According to its prospectus, Mifei Technology focuses intensely on the core technology development and industrial application of Automated Material Handling Systems (AMHS) for semiconductor wafer fabs. It is one of the very few domestic suppliers in mainland China that holds independent intellectual property rights for core AMHS technologies, aligns key technical indicators with international advanced levels, and can provide various AMHS hardware and software systems for semiconductor wafer fabs. As one of the rare domestic suppliers to have completed full-factory acceptance in both 8-inch and 12-inch wafer fabs, the company has leveraged its deep technical expertise and continuous innovation capability to enter the supply chains of well-known domestic and international semiconductor companies. It has grown into a leading enterprise capable of delivering complete AMHS product projects to global semiconductor customers.

Xiahe Technology, with CITIC Securities as its sponsor, aims to raise 600 million yuan. The prospectus shows that Xiahe Technology's main business is the research, production, and sale of OLED organic terminal materials, primarily doping materials. The company has successfully mass-produced multiple OLED doping materials with independent intellectual property rights. These include green light doping materials (GD) and red light doping materials (RD) for the emission layer, as well as P-type conductive doping materials (PD) for the charge generation layer and hole injection layer. Additionally, the company has a small business in red light host materials (RH) and green light host materials (GH) for the emission layer.

Silang Technology, also sponsored by Guotai Junan Securities, seeks to raise 4.426 billion yuan. According to its prospectus, Silang Technology is engaged in the design and development of chips, application software and platforms, boards, and complete systems. Core modules including chips, high-speed boards, liquid cooling systems, and complete system architecture are all independently developed by the company. The manufacturing and production processes are outsourced. The company focuses on independent R&D and industrial application of chips based on its proprietary high-performance kernel architecture, MaPU. To meet the demands of surging data volumes and complex computing loads, it provides hardware and software products and solutions centered around its self-developed chips.
