Spintronics combines semiconductor technology with electron spin to develop faster, lower-power memory, magnetic sensors, quantum devices, and next-generation computing systems. UniversityWafer supplies high-quality silicon wafers, thermal oxide silicon wafers, GaAs substrates, sapphire wafers, and other semiconductor substrates used for magnetic thin-film deposition, spintronic nanostructures, and advanced materials research.
A professor of Electrical and Computer Engineering requested a quote for silicon substrates used to grow magnetic thin-film stacks for spintronic device research.
Research Application:
Our application is to grow magnetic thin-film stacks for spintronic nanostructures. The silicon wafer serves only as the substrate, so electrical conductivity through the wafer is not required.
We need a smooth, electrically insulated surface with 50-150 nm of SiO2 to support magnetic film deposition. Previously we evaluated both test-grade silicon wafers with 100 nm wet thermal oxide and prime-grade silicon wafers with 100 nm dry thermal oxide for this application.
Reference #273859 is available for specifications and pricing.
UniversityWafer supplies silicon wafers with thermal oxide for spintronics, magnetic tunnel junctions (MTJs), magnetic thin-film deposition, and other advanced semiconductor research. Custom oxide thicknesses, wafer diameters, crystal orientations, dopants, and polish options are available.

Spintronics, also known as spin electronics, is an advanced field of semiconductor research that uses the electron’s spin and magnetic moment, in addition to its electrical charge, to store, transfer, and process information.
Unlike traditional electronics, which rely mainly on moving electrical charge through a circuit, spintronic devices use spin states such as “up” and “down” as an additional way to represent information. This makes spintronics important for research in non-volatile memory, magnetic sensors, quantum devices, low-power electronics, and next-generation data storage.
Spintronic materials and devices are studied because they may help improve speed, energy efficiency, and data retention compared with conventional electronic devices. Applications include MRAM magnetic random-access memory, magnetic tunnel junctions, spin valves, spin filters, spin transistors, and quantum computing structures.
The substrate is important because it supports the magnetic and non-magnetic thin-film layers used in spintronic devices. Researchers often need smooth, insulating, and thermally stable surfaces for growing magnetic thin-film stacks, tunnel barriers, and nanoscale device structures.
Common substrates used for spintronics include:
Many spintronics researchers use silicon wafers with thermal oxide to grow magnetic thin-film stacks. A SiO2 layer can provide electrical insulation, surface smoothness, and separation between the silicon substrate and the magnetic materials deposited on top.
For spintronic nanostructures, common specifications include wafer diameter, oxide thickness, surface polish, dopant type, resistivity, orientation, and total thickness variation. Silicon wafers with 50 nm to 150 nm SiO2 are often requested for research involving magnetic layers and insulating surfaces.
