Global Leadership

The ASE is the leading provider of independent semiconductor manufacturing services in assembly and test. The group develops and offers complete turnkey solutions covering IC packaging, design and production of interconnect materials, front-end engineering test, wafer probing and final test, as well as electronic manufacturing services through USI, Inc. As global leader, ASE provides a complete scope of services for the semiconductor market, driven by superior technologies, breakthrough innovations, and advanced development programs.

Semiconductors are the basic building blocks used to create electronic products and systems. Increasingly we are moving towards more sophisticated semiconductor applications, driven by market demands for faster, smarter, portable and integrated electronic products. In such products, the tiny semiconductor chip is constantly being pushed to greater limits.

Semiconductor manufacturing consists of many processes - design of the integrated circuit (IC), preliminary testing of the viability of the design, wafer fabrication, packaging and final testing of the IC.

Our Capabilities

ASE is capable of providing services at all stages of the semiconductor manufacturing process, with the exception of wafer fabrication. Our service capabilities range from front-end engineering testing, wafer probing, packaging and final test. We also provide design manufacturing service from board design to systems assembly through USI, Inc., an ASE member.

Front-end engineering test is the testing of semiconductor prototypes before they go into volume production. Our services include software development, electrical verification, reliability analysis and failure analysis.

Wafer probing is a process whereby each individual die (chip) on the wafer is tested for defects to identify operable semiconductors for packaging. Packaging, also known as assembly, is the processing of bare semiconductors into finished semiconductors, serving to protect the die and facilitate electrical connections and heat dissipation. We offer a broad range of semiconductor packages meeting the diverse function and cost requirements of our customers.

Final testing of semiconductors ensures that they function properly before being shipped to customers or assembled in electronic products.

State-of-the-art Process Technologies

As the industry focuses on integrating more functions onto a single chip and chip performance increases with improvements in process technologies, packaging has gained even greater importance. Computing frequency of next generation chips are becoming higher and functions packed onto each chip are increasing. Consequently, requirements for thermal and electrical reliability are rising exponentially.
Semiconductor designers need to explore advanced packaging methods to satisfy these requirements.

Innovation and quality are values that ASE prides itself for delivering leading-edge technologies and solutions to customers, meeting their demanding requirements such as electrical performance, heat dissipation, cost and aggressive cycle time. ASE continues to invest the maximum in research and development through its high caliber engineering teams and advanced manufacturing processes.

Chip designers continue to pack more functions onto a shrinking chip size and demanding better performance, and greater speed. This increasing complexity of the integrated chip has posed much challenge to the manufacturing process.

In keeping with the advances in chip development, ASE maintains a highly experienced and skilled engineering team that continuously research and develop the latest assembly technologies. ASE also invests prudently in the latest equipment and state-of-art facilities, making us a true extension of our customers’ manufacturing operations.

As an industry leader, ASE was the first to achieve volume production for Cu Wire Bonding, Wafer Bumping, Cu Pillar Bump, Flip Chip, Chip Scale Package (CSP), PoP, and System in Package (SiP), MEMS & Sensor Packaging, Fan Out, 2.5D/3D IC Packaging, Green Packaging and 300mm turnkey backend solutions. Customers are the direct benefactors of this lead in advanced technology.
