SIMOX SOI Wafers to Fabricate Devices

We use SOI for our device work – usually as 10 mm x 10 mm or 15 mm x 15 mm chips - so youll appreciate that one-off 200 mm wafer should keep us well supplied for some time. To make our devices (single electron transistors) we have to have a highly n-doped device layer - a virtual conductor – but if required we can use a spin-on dopant to generate this ourselves. I dont think any of your material has the necessary doping level – but thats no problem Your SIMOX SOI Part 2551 might well furnish our need. I am unclear as to the formalities required to purchase from one wafer from you. Are you able to send a quote so that I can place an order and will that include custom clearance, packing and and postage.

Ultra-Thin Silicon Wafers

We plan to do PVD coating on this wafer. Our coating system has a 4” diameter mounting surface. The wafer must be mounted on this surface so it must not fracture when bent to a radius of 50.8 mm. We think a polished high quality crystal of 50 micron thickness should have a critical bending radius of about 37 mm. We have a reel-to-reel coating system that can do several square meters of coating per day. We think this system might be great for coating of Solar Panels and other high volume needs. I have attached a publication reporting bending studies on 50 um silicon.

2 micron thin available

25.4mm Silicon Wafers

University researchers and industry scientists use 1 inch silicon wafers for their projects because they are easy to work with and inexpensive equipment is readily available. Small diameter wafers are a low-cost alternative to larger diameter wafers which cost more and require more expensive equipment.

 

Typical researcher quote request.

 

"Please, send us quotation for ten zero-diffraction plates for powder XRD with following specs: Diameter 32 mm Thickness approx 2 mm Single Side Polished w/o cavity Example - Off orientation 9° of (001) or other Thank you in advance."

50.8mm Silicon Wafers

(100) (111) (110) & Other Orientations

 

I'm wondering if you have silicon wafers that are polished on both sides.

I need only one or two wafers, ~2 inch diameter, 0.5-1 mm thick. I use them as dichroic mirrors (transmit IR and reflect visible light). Most importantly they have to be polished on both sides.

76.2mm Silicon Wafers

UniversityWafer, Inc. is mentioned in over 20,000 academic research papers. Below is a typical interaction.

 

Hello! We are looking for a product that was referenced in some publications : “Silicon wafers (3-inch diameter, Type-P, 1S polished; University Wafer, cat. no. S3P01SP” (referenced by doi:10.1038/nprot.2013.046) However I cannot find that product on your web site. Do you have any suggestions of which product might work for the same applications? I was thinking that # 978 would probably work (7.6 cm, single side polished, type p) but was not sure. Can you maybe confirm?

Single and Double Side Polished

 

Material, life sciences and nanomedicine researchers have used 76.2mm Silicon Wafer Item #1318 to measure the dimensions of nanoscale objects.

100mm Silicon Wafer

Float Zone (Fz), Czochralski (Cz)

 

Research requests the following:

I am interested in ordering a batch of 4-inch diameter Si wafers. They need only be polished on one surface and of mechanical grade (test and prime also available) Si as they are to be used mostly as carrier wafers in semiconductor fab processes. I would be looking for at least 10 but we are interested in what kinds of bulk discounts you can offer for low-grade Si wafers as we may buy a lot. Many thanks in advance for your help!

150mm Silicon Wafer

Highly Doped and Low Doping

We are looking for low doped silicon wafers for FTIR measurements. On your website, the following has been referenced for such application. 6” DSP wafers,Work well for IR are spec’d at: Type: P Dopant: Boron Resistivity: 10 – 20 Ohm cm Orientation: <100> Thickness: 625± 25um What would be the transmission of this wafer in 400-4000 cm-1 range?

Float Zone (FZ) Silicon Wafers

This is a typical interaction we have with our research clients:

 

Hi, I am after a range of wafers to study surface passivation and bulk properties after solar cell processing.

Anything already in stock is preferable as I am looking to source some wafers as quickly as possible, if you have anything suitable for the following:

• ~15x FZ, 100, high resistivity (n-type >20ohm-cm), double sided polished, 200-500um, 2inch?
• ~20x FZ, 100, 5-10 ohm-cm n-type, double sided polished, 150-400um, 4inch?
• ~20x FZ, 100, 5-10 ohm-cm p-type, double sided polished, 150-400um, 4inch? (p-type equivalent of previous point – ideally as close as possible in specs)
• ~10x FZ, 100, 1-10 ohm-cm n-type, surface not critical, 200-400um, 4inch?
• ~40x FZ, 100, 0.5-5 ohm-cm p-type, surface not critical, 200-400um, 4inch?
• ~20x FZ, 100, 0.5 ohm-cm, polished or other?, 300-500um, 4 inch? Ideally sisters and low carbon concentration I look forward to hearing the options!
