ASMPT Extends Technology Leadership With Key TCB AOR Chip-To-Wafer Milestone

February 7, 2026 - 03:18

In a significant stride for the semiconductor manufacturing industry, ASMPT has announced a key technological milestone in its Thermal Compression Bonding (TCB) process. The company has successfully developed and qualified its proprietary Array-On-Reconstituted-wafer (AOR) chip-to-wafer bonding technology, a crucial advancement for next-generation high-performance computing and artificial intelligence applications.

This breakthrough specifically addresses the immense challenges of packaging increasingly complex and powerful chips. The AOR methodology allows multiple known-good-die chips to be bonded onto a reconstituted wafer with exceptional precision and yield. By mastering this technique, ASMPT enables the creation of advanced 2.5D and 3D integrated circuits that are essential for pushing the boundaries of data processing speeds and energy efficiency.

The successful qualification of this process marks a pivotal step in extending the roadmap for heterogeneous integration, where different chip components are combined into a single, powerful package. This advancement solidifies the industry's path toward more powerful, compact, and efficient electronic devices, from data center servers to cutting-edge consumer electronics. The achievement underscores the ongoing innovation required to sustain the pace of technological progress as traditional semiconductor scaling becomes more difficult.
