![]() ![]() We have Ultra-Flat Silicon with the following spec Recent Silicon Wafer FAQs What is surface flatness of silicon wafer? We have undoped, low doped and highly doped Silicon substrates that are always in stock. We can custom make wafers in small quantities. If you need to use bare Si cleaning prior use is inevitable. However they oxidize and passivate very quickly. 1 Ohm cm, dia 1", thickness 500um (but is not critical), 10 pcs.Īll wafers we offer are HF-etched and cleaned before sale. The other specs would be p-type Silicon, cut (100), ca. Once a Si waver is HF ezched, how long can one keep it before it oxidizes again? HF etched p-type Silicon Wafers (to Remove SiO2)Ĭan you provide HF etched p-type Si wafers (to remove SiO2), so that we don't have to go the rather scary procedure to do it here. Please see a photo of the wafer after the diffusion process. With Diffused Phosphorus layer ~500nm thick, Nc~5E19/cm³, Ro~0.001 Ohmcm, One-side-polished, back-side Alkaline etched, Please let me know what you need in more detail and we return with the quote.īetter performance you achieve using higher concentrations. Process temperature is approximately 1000-1100° C. After the diffusion we remove the appearing oxides. Concentrations that are available are up to ~5E19/cm³. Boron element (p-type) we can diffuse into the depth from 0.5 µm to maximum ~3µm. I attach the photos of the wafers after the process. We have a facility to make the diffusion and create p on n PV-Si wafers. Probably within 10 or may be higher.Īlso, do you have GaInP PV cells? Can you provide me details?Ĭan you please let me know if you have any other doping profile which can provide better performance?Īlso, can you provide rough estimation of price for the same size and depth as you had attached in last email. Can you please provide me detail on this?Ĭan you please list out available such PVs with specifications? I don’t need a lot. I need a diffusion doped “p on n Si” wafers. Where Can I Find Diffusion Doped P on N PV-Silicon Wafers?Ī scientist asked us to quote the following: Note: It is not recommended to use Epi substrates normally, as these pieces are shaped like cakes and the 111 materials are therefore not ideal for use in high-performance silicon cells. P wafers can have an epi substrate, which is normally used for bipolar devices such as solar cells, solar cells and solar modules. P-type wafers are heavily doped with 111 materials used in research and development lithography and are therefore not suitable for SEM analysis. ![]() P-type silicon wafers for use in high performance, energy efficient and energy efficient applications such as solar cells and solar cells.

Research scientists have used the following specs to fabricate sensors in a cleanroom environment.ġ00mm P/Boron (100) 3000-4000 ohm-cm 500+/-15um SSP PRIME High Resistivity P-Type Silicon Wafers for Sensor Fabrication You can also make your own quote form the shopping cart. Please let us know what specs and quantity we can quote for you! Send P-type Si Wafer in Hard Plastic Cassette See bottom of page for recent Silicon Wafers specials. Fill out the form and receive an immediate quote. We need a wafer that is less than 500 microns thick. It worked nicely and we are looking to do the same thing with Ge (Germanium Wafer). We used one of Scott's old Si wafers (doped with B) and broke off a strip of Si that we attached to electrodes in our EEW apparatus. We make nanomaterials in our lab and one approach is using electrical explosion of wires (EEW). If you have any advice on specific types of wafers we will need for such nano electronic devices I would be happy to know. We need a substrate to pattern with photolithography and subsequently deposit various precious metals on that will catalyze certain reactions and conduct electricity. I am in a group that is working on a Senior Design Project to create a biobattery. ![]() Let us know how we can help you.Īfter looking at your online store, I think we might go with your cheapest silicon wafers, product D 444. Typical Client Question regarding p-type silicon wafers:īelow is a typical interaction with a research client. ![]()
