What Is the Definition of Black Silicon Wafers

"Black" Silicon requires the surface of silicon wafers to be etched so as to absorb incomming radiation - so they look "black."

What Silicon Wafer Spec Should I use for Calibrating?

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

Who Makes the Best Silicon Wafers?

Who Makes the Best Silicon Wafers in the World? This question is a common one. There are many companies that produce semiconductor-grade silicon wafers, but few are truly leaders in their field. These companies are often dependent on large volumes of silicon. Some of these firms are more successful than others, but there are a few key differences that you need to understand. The company with the most technologically advanced wafer production processes is SUMCO.

UniversityWafer, Inc source it's wafers from SUMCO and some of the companies below. Thus clients can be ensured that they received only the highest quality substrates.


A few of the biggest names in the semiconductor industry produce silicon wafers, including GlobalWafers, Xilinx, and Infineon Technologies. These companies compete in the global market for these wafers, and they are ranked by market share. If you are looking to buy silicon nitride wafers, check out these companies. If you are in the market for these products, you can't go wrong with any of them.

GlobalWafers: This Taiwanese semiconductor company is located in a boxy off-white office building. The workers are adorned in colorful protective suits. You can also see "claw machines" - named after the arcade game, which hauls nine kilograms of silicon wafers. These machines are designed to extract individual silicon wafers, and each one must undergo six to eight weeks of testing before they're ready to be carved into individual chips.

Who Makes Silicon Wafers in the United States?

It is unclear who makes silicon wafers in the United States, but the answer lies in the semiconductor industry. Today, Asia produces three-quarters of the world's semiconductors, while the United States produces just 13 percent.


UniversityWafer, Inc. is the closest to a US based silicon fabrication plant. UniversityWafer, Inc. and partners have business relationships with plants all over the world to bring our clients the best quality silicon wafers at the lowest cost price in the quantities clients want.


The Senate has passed a bill that authorizes $52 billion in subsidies for new factories. One company that employs hundreds of people in Albany, New York, is GlobalFoundries. The company runs twenty-four hours a day and pumps out 500,000 silicon 'wafers' a year. It then cuts those silicon wafers into chips.

The process of making a silicon wafer requires a variety of processes. High-purity silicon is obtained through the synthesis of silica or silicon metal. Then, the silicon ingot is sliced into wafers. The final product is known as a monocrystalline silicon wafer or epi-crystalline silicon, which is suitable for a variety of applications including computer chips and photovoltaics.

In order to make a semiconductor, the material must not be an excellent conductor of electricity. The most common types of semiconductor material are silicon, germanium, gallium arsenide, and silicon carbide. These materials are fabricated into thin-films, modules, and solar cells. These wafers are available in several sizes, and can be customized based on your specifications. The thickness of the silicon wafers varies from one ohm to 30 ohms.


Recent Silicon Wafer Frequently Asked Questions (FAQs)

Q. What is surface flatness of silicon wafer?

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 .

Q. What is the definition of silicon wafers?

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.

Q. Do you sell platinised silicon wafers?

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!

Q. Do you sell one silicon wafer? If so, how?

A. Yes! We sell as few as one Silicon wafer. We sell in individual wafer carrier.

Q. How do you clean Si 100 wafer before silicon dioxide is formed for bump production?

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)

 Q. Can you resize silicon wafers from 200mm to 100mm?

 A. Yes! We can laser down the wafer so you could get two 100mm from one 200mm wafers including flats!

 Q. What is silicon wafer reclaim?

 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.

What silicon wafer thickness Range Do I Need?

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.
