Special Session 4 (Flyer Download)
Topic: Advanced Microjoining for Nanomaterials
Organizers: Assoc. Prof. Yaotian Yan, Harbin Institute of Technology, China & Dr. Yanyu Song, Harbin Institute of Technology, China & Dr. Peixin Li, Harbin Institute of Technology, China
Introduction:
The precise fabrication of microjoined structures and
the reliable formation of joining interfaces have become
central objectives in modern materials engineering and
microdevice manufacturing. However, traditional
microjoining techniques still face challenges, such as
poor interfacial integrity, uncontrolled microstructural
evolution, and limited process stability, which hinder
the reliability, performance, and miniaturization of
advanced devices.
Recent breakthroughs in process control and interface
engineering have led to the development of advanced
microjoining, which are now widely applied in fields
such as advanced energy materials, semiconductor
packaging, and microelectromechanical systems (MEMS).
The precise design of joining processes and the
optimization of interfacial microstructures are critical
for improving the mechanical, electrical, and thermal
properties of joined structures. In this context,
advanced characterization tools—such as atomic-scale
transmission electron microscopy (TEM)—provide valuable
insights into the microjoining interface, enabling a
deeper insight on structure and property. Consequently,
these combined advancements in process control,
interface engineering, and characterization
significantly improve device reliability, manufacturing
yield, and long-term stability.
Focusing on the innovative design of microjoining
processes, controllable fabrication of joint
microstructures, and their application in high-precision
manufacturing and device integration, will greatly drive
the development of this field.
