What are wafer substrates used for in research labs?

Wafer substrates are used as flat, controlled surfaces for thin film deposition, lithography, device prototyping, optics, MEMS, power electronics, and materials characterization. Common choices include silicon, SOI, thermal oxide, SiC, GaN, sapphire, quartz, glass, graphene, and ITO.

How do I choose between silicon, SOI, and sapphire?

Silicon is a standard low-cost semiconductor platform. SOI adds an insulating layer that helps reduce parasitics and improve isolation. Sapphire is an insulating, optically transparent substrate often used for RF, optoelectronics, and GaN-based devices.

What is thermal oxide on silicon used for?

Thermal oxide (SiO2) on silicon is commonly used as an insulating layer, gate oxide, masking layer, or surface passivation for microfabrication and device processing.
