Aluminum-Coated Silicon Substrates (Al/Ti on Si (100))
Overview
Our aluminum-coated silicon substrates are precision-cut from research-grade Al thin film wafers fabricated on Si (100) substrates using high-vacuum magnetron sputtering.
A 10 nm titanium (Ti) adhesion layer is deposited between the silicon substrate and the aluminum film to ensure reliable interfacial bonding and stable electrical performance.
Aluminum thin films are widely used in microelectronics research, reflective coatings, MEMS fabrication, interconnect studies, and conductive layer development.
