After looking at your online store, I think we might go with your cheapest silicon wafers, product ID 444. I am in a group that is working on a Senior Design Project to create a biobattery. We need a substrate to pattern with photolithography and subsequently deposit various precious metals on that will catalyze certain reactions and conduct electricity. If you have any advice on specific types of wafers we will need for such nano electronic devices I would be happy to know. Thanks.
We make nanomaterials in our lab and one approach is using electrical explosion of wires (EEW). 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. It worked nicely and we are looking to do the same thing with Ge (Germanium Wafer). We need a wafer that is less than 500 microns thick. Fill out the form and receive an immediate quote.

P-type silicon wafers for use in high performance, energy efficient and energy efficient applications such as solar cells and solar cells.
P-type wafers are heavily doped with 111 materials used in research and development lithography and are therefore not suitable for SEM analysis. P wafers can have an epi substrate, which is normally used for bipolar devices such as solar cells, solar cells and solar modules. 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.

The majority of our Prime Grade wafers have a roughness value Ra<5Å.
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.
Yes! We sell Platinised and thin films of almost all the metals! Just let us know the specs and quantity for an immediate quote!
Yes! We sell as few as one Silicon wafer. We sell in individual wafer carrier.
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. 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)
Yes! We can laser down the wafer so you could get two 100mm from one 200mm wafers including flats!
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.

This paper will examine the most important issues in the development of n-type silicon-based solar cells, progress in addressing them and their potential applications. In the following section we describe the manufacturing processes of solar cells, in which crystalline silicon of type N is used as the base absorber material for the main solar cell manufacturing process.

P-type cells, the raw materials that precede the drawing and cutting of silicon wafers, are the same for P and N cell types. [Sources: 2]
In the case of P silicon, the minority carrier for N silicon is a hole instead of an electron, and this type of silicon offers a higher minority carrier diffusion length compared to other silicon types, such as boron silicon wafers. The results suggest that the reduction in the widespread defects is partly due to the use of a more efficient method of using these silicon types. P cells normally dock the cells on the silicon wafer with a mixture of borson, which has one electron less than silicon, to form a positively charged cell. In this case, a high efficiency of the cell is achieved in the millisecond range by placing a minority of carriers for both P-type and N-type semiconductors in a single wafer, but the higher efficiency cell, where higher efficiency is required.

N - Silicon has a longer life span when Cr is 100% (partially or completely) associated with the carrier, with a life span of at least 10 years. Since it does not contain boron - related defects (in contrast to p - silicon species), it is reported that the life of carrier minorities is limited by grown - to - point defects. [Sources: 0]
Extended defects are visible in the crucible - grown - straightened - solidified silicon - which forms the basis for the cultivation of silicon solar cells (including the use of p - silicon wafers as shown in FIG). 1, listed below). This process makes the solar cell 100%, and it is expected that the process can include a large number of different types of carrier minerals (e.g. boron, beryllium, etc.). There are ongoing efforts to make cells from thin silicon wafers and improve the design of thinner silicon solar cells. [Sources: 0, 7]
This can be used to make small silicon substrates by breaking the wafers into small pieces, such as the EWT cells shown in FIG. 1, made from the crucible - cultivated - straightened - solidified silicon (P - silicon) wafer (listed below). This has the advantage that WAFers can be grown from materials other than silicon and has the potential to produce solar cells with a variety of carrier minerals and other materials. This can cause problems in the production of thin silicon cells, but also a number of advantages over conventional silicon solar cells. [Sources: 4, 5, 8]
P - silicon wafers from crucible - cultured - straightened - solidified silicon wafers (P - silicon) (listed below) to large - split, larger - than normal silicon wafers (Fig. 2). [Sources: 6]
A comparison of the device characteristics is shown, and the measured values (e) are 1.45 or 1: 35. P - Crucible silicon wafers - cultured - straightened - solidified - solids (R & S) too large - split, larger - than - normal silicon wafers (P- silicon) wafers (Fig. 3). The measured value of F & S is measured for the material silicon by a factor of 2.5 or 1 / 2 for the mass or mass material. A solar cell that uses a fission-forming silicon wafer is a 1-to-35 wafer that is closer to 1 than the solar cells that consume most of a silicon wafer. Solar cells are used in a wide range of applications, such as solar panels, photovoltaic cells, solar power plants and solar thermal cells. [Sources: 6]
