ASE TEST INC

Business Type: Factory / Manufacturer

Company Introduction:

ASE Technology Holding Co., Ltd. is the world's largest independent provider of semiconductor assembly and test manufacturing services. Headquartered in Taiwan, the company offers a comprehensive range of services, including advanced semiconductor packaging, testing, materials, and electronic manufacturing services (EMS).

ASE Test, as an integral part of ASE Technology Holding Co., Ltd., specializes in providing critical semiconductor testing services. These services encompass wafer probing, final test, and burn-in for a vast array of integrated circuits. These testing operations are essential stages in the semiconductor manufacturing process, ensuring the quality, functionality, and reliability of chips before they are delivered to customers.

Therefore, ASE Technology Holding Co., Ltd. (and its testing operations, ASE Test) functions as a factory and a high-tech manufacturing service provider, directly involved in the production and quality assurance of semiconductor components, rather than operating as a trading company.

ASE Technology Holding Co., Ltd., which includes what was formerly known as ASE TEST INC, primarily produces and sells services and components related to semiconductor manufacturing. Their main offerings are:

1. Semiconductor Assembly Services: This involves packaging integrated circuits (ICs) using various technologies such as wire bonding, flip chip, wafer-level packaging, system-in-package (SiP), and advanced 3D packaging solutions.

2. Semiconductor Testing Services: They provide comprehensive testing solutions for integrated circuits, including wafer probe, final test, burn-in, and system-level test to ensure functionality and reliability.

3. Electronic Manufacturing Services (EMS): Through its subsidiary Universal Scientific Industrial (USI), ASE offers design, manufacturing, and assembly services for electronic modules and systems across diverse applications like automotive, industrial, medical, and consumer electronics.

4. Materials and Substrates: They also produce and supply the substrates and materials necessary for their advanced packaging processes.
