Do you guys Make aluminum substrates?

We would like to coat Boron-10 on 0.25 mm thick and 4” diameter or bigger? Aluminum substrate.

We provided:

Diameter 4 inch
Thickness 0.3mm SSP


Do you offer any aluminum-coated 4-inch silicon wafers?

We’re looking for 10 nm Ti + 100 nm Al, or something comparable. We just need the top layer to be Al. Initially we’d like a quantity of about 20.

We quoted:

100mm P/B (100) 500um Al/Ti SSP 8-12 ohm-cm SEMI Prime, 2Flats, PF@<100>±1°, SF 45° CW from PF, with 10nm barrier layer of Ti & 100nm±5% layer of Al on polished side only, in Empak cst

Above we offer Silicon wafers with 100nm layer of pure Aluminium over the polished side.

We can also offer a layer of 99.5%Al 0.5%Cu or 98%Al 2.0%Cu in place of 100%Al, at the same price.

In the past you have been able to supply us with aluminized silicon wafers

Im hoping you can do that for us again. Here are the specs:

Required:
Diameter: 25.4mm diameter, +0, -150 microns
Aluminum on ONE polished surface, thickness >=50 nm.

Preferences:
No flat is GREATLY preferred
Orientation: <100>
Dopant: undoped, but no real requirement
Preferably DSP
Thickness: <300 microns, 280 micron preferred.
Resistivity: <10,000 ohm-cm

Well order at least 25 units.

I am looking for aluminum wafers, 3" and 4" , DSP, 0.5 mm and thicker, 5 pcs of each. Can you help?

 

We sold

3" SSP 0.5 mm and thicker

4" SSP 0.5 mm and thicker
