Where Can You Buy Silicon Wafers Online?
UniversityWafer, Inc. supplies silicon wafers for sale in small research quantities and larger production volumes. Researchers, engineers, universities, government labs, and semiconductor companies buy silicon wafers for spin coating, microfluidics, photolithography, thin film deposition, Raman spectroscopy, MEMS, porous silicon research, and semiconductor device fabrication.
Choosing where to buy silicon wafers can be confusing because wafer price depends on diameter, grade, dopant, orientation, resistivity, thickness, polish, oxide layer, and quantity. UniversityWafer, Inc. helps researchers compare specifications and source the right wafer for their process.
Test Grade Silicon Wafers for Spin Coating and Microfluidics
Test grade silicon wafers are a cost-effective choice when the wafer is used as a flat, strong substrate rather than as the active electronic material. These wafers are commonly used for spin coating, photoresist testing, polymer coating, template fabrication, and microfluidic device research.
Research request: A senior scientist requested 25 test grade 100mm silicon wafers for normal spin coating and making templates for microfluidics. Reference #90838 for specs and pricing.
Silicon Wafers Used as Resist Substrates
Many researchers buy silicon wafers as low-cost substrates for photoresist, polymers, thin films, and experimental coatings. For these applications, single-side polished silicon wafers or double-side polished wafers may be selected depending on surface quality requirements.
Research request: A Ph.D. researcher needed affordable 3 inch N-type or P-type silicon wafers for use as strong, flat, polished substrates for resist research. Test grade quality was acceptable, with quantities between 20 and 100 wafers. Reference #110096 for specs and pricing.
High Resistivity Silicon for Porous Silicon Research
High-resistivity silicon wafers are used in porous silicon, sensors, RF devices, detectors, photonics, and electrochemical etching research. Researchers may also request thermal oxide silicon wafers when a silicon dioxide layer is required for insulation, masking, or porous silicon studies.
Research request: A senior research fellow requested 4 inch high-resistivity silicon wafers with or without an oxidized layer, including silicon dioxide for oxidized porous silicon research. Reference #130638 for specs and pricing.
Silicon Wafer Discs for University Research
UniversityWafer, Inc. supplies silicon wafers, silicon discs, diced pieces, and custom substrate sizes for university research. Researchers can request specific diameter, orientation, dopant, resistivity, thickness, and polish requirements.
Research request: An electrical engineer requested N-type silicon wafer discs with (111) orientation and custom 4 inch by 4 inch or 8 inch by 8 inch sizing. Reference #123287 for specs and pricing.
Silicon Wafers for P-N Junction and Interface Research
Silicon wafers are also used to fabricate P-N junctions, p-n interfaces, doped layers, power devices, diode structures, and semiconductor test devices. Researchers may request low-resistivity P-type or N-type silicon wafers with SSP or DSP polish, specific orientation, and controlled dopant profiles.
Research request: A Ph.D. student requested low-resistivity silicon wafers with P-N interfaces, 2 inch to 4 inch diameter, 200-400µm thickness, SSP or DSP polish, and resistivity from 0.01 to 0.001 Ω-cm. Reference #142344 for specs and pricing.
