"The (silicon) wafers have arrived today, and we really pleased with them! Thumbs up to your production crew!"
Researcher from University of Exeter Free Silicon Wafer Support on All Substrates!
Researchers have used the wafers below to make lenses in photonic integrated circuits.
Item# 1720 Silicon 100mm P /B <100> 1-20 200um DSP
"Black" Silicon requires the surface of silicon wafers to be etched so as to absorb incomming radiation - so they look "black."
We are looking for materials that are 1.5mm and 2mm thick for calibrating some of our cutting? Silicon is preferred, but the blade can handle a smaller diameter glass substrate as well.
Other specs don't matter. We just used these as blanks and dice into them to align the camera to the disco.
UniversityWafer, Inc. Provided:
1. 100mm Silicon materials that are 1.5mm thick for calibrating some of our cutting,S ingle side polished,qty. 25pcs
2. 100mm Silicon materials that are 2mm thick for calibrating some of our cutting, Single side polished,qty. 25pcs
High Certified Bulk Lifetime Silicon Wafers
A scientist requested the following:
"I am looking for some n-type phosphorous doped double side polished wafers with high certified bulk lifetimes (FZ). I need the wafers to have certified bulk lifetimes, very important. let me know if you have any products that would fit this description. I am trying to demonstrate a new passivation technology so that I can apply for better funding later on."
The scientist purchased the following:
Si Item #G962
100m N/Ph (111) 240 ±10 micron E/E FZ 2.81--3.06 ohm-cm
We have all MSDS and other spec sheets available upon request.

A. We have Ultra-Flat Silicon with the following spec
Prime Silicon Wafers
100mm P-type /Boron doped <1-0-0> 490-510 micron 0.005-.020 ohm-cm Semi Std Double Side Polished
Total Thickness Variation (TTV)<1 um. These are great for making SOI or MEMS!
Q. What is the roughness value (rms) silicon wafer?
A. The majority of our Prime Grade wafers have a roughness value Ra<5Å .
A. A Si wafer, or substrate, or silicon is grown in a tube from a seed into a long ingot that is then sliced into various thicknesses used in electronics for the fabrication of integrated circuits and in photovoltaics. The wafer serves as the substrate for microelectronic devices built in and over the wafer and undergoes many microfabrication process steps such as doping or ion implantation, etching, deposition of various materials, and photolithographic patterning. Finally the individual microcircuits are separated (dicing) and packaged.
A. Yes! We sell Platinised silicon wafers and thin films of almost all the metals! Just let us know the specs and quantity for an immediate quote!
A. Yes! We sell as few as one Silicon wafer. We sell in individual wafer carrier.
A. The RCA clean is a standard set of wafer cleaning steps which need to be performed before high-temperature processing steps (oxidation, diffusion, CVD) of silicon wafers in semiconductor manufacturing.
Werner Kern developed the basic procedure in 1965 while working for RCA, the Radio Corporation of America.[1][2][3] It involves the following chemical processes performed in sequence:
Removal of the organic contaminants (organic clean + particle clean)
Removal of thin oxide layer (oxide strip, optional)
Removal of ionic contamination (ionic clean)
A. Yes! We can laser down the wafer so you could get two 100mm from one 200mm wafers including flats!
A. It's when you have a wafer that has thin films or oxide etc on them and we strip and clean them so the wafers can be reused.
Often companies that want to save money or protect their intellectual property will reclaim their wafers.
All Silicon wafer thicknesses have a range. Some wafer specs have a tighter range than others and are considered flatter than standard range silicon wafers. Let us know what your research is and we'll quote you the correct wafer thickness.
