Technical Name MICAtronics: A Universal Platform for Fabricating Atomically Flat Single-Crystal Metal and Oxide Films
Project Operator National Tsing Hua University
Project Host 朱英豪
Summary
Centering on the Micatronics platform, this technology utilizes the van der Waals epitaxy and flexibility of mica to develop atomically smooth, high-quality single-crystal thin films, including metals (Cu, Ag, Pt, Co, Ni, HEA) and oxides (ZnO, β-Ga2O3). Through electroplating and spontaneous exfoliation, we achieve a large-area, transferable single-crystal platform that significantly enhances 2D material and semiconductor performance while drastically reducing costs.
Scientific Breakthrough
This technology integrates vdW epitaxy and spontaneous exfoliation to create an atomically smooth Micatronics platform. Unlike costly, size-limited commercial single-crystal foils, our method leverages mica’s dangling-bond-free surface to bypass lattice mismatch, producing large-area metal and oxide films with bulk-like quality. By utilizing stress-controlled delamination, we ensure damage-free transfer and substrate reusability, drastically cutting costs for next-gen heterointegration.
Industrial Applicability
This technology provides large-area single-crystal metal and oxide platforms for semiconductor packaging, 2D materials, 6G THz communications, and power devices. It enhances Cu–Cu bonding reliability by reducing IMC formation, and serves as an epitaxial substrate for 2D materials. Atomically flat surfaces reduce high-frequency signal loss and scattering. It also improves heat dissipation in Ga2O3 devices via copper backplanes, enabling a low-cost and scalable heterogeneous integration platform.
