High Temperature Glass 1

[layertransfer]

I am looking for a high temperature glass that can be processed at >650C. Is there such a glass?

 

[IRstuff]

processed how?

TTFN

CMOS / semiconductor processing - thin film growth and depositions.

 

[IRstuff]

Then, any deposited oxide will meet that requirement, except for the slurry stuff.

I need to clarify my interest / question ..... I am looking for a glass substrate (high temp glass, vendor, etc.) of which I transfer a thin layer of semiconductor material. I then need to do some additonal processing which require process tempertures of >650C.

Have you ANY idea of what you're doing?
Is this for a class?

You cannot willy-nilly select a substrate to deposit semiconductor material and expect reasonable performance. What material EXACTLY?

And what processing are you doing at only 650ºC? That's too low for anything except CVD.

My question was simple, is there a glass substrate sucb as from Corning, Ashai Glass, Hoya, or any other manufacturer of glass substrates that can handle process temperature > 650C.

The question was not to deposit a CVD glass ..... it was to select a substrate with thermal stability properties that can withstand process temperatures >650C.

Thanks for your response, but if don't understand the question ........... that's OK.

 

[IRstuff]

My point is that ANY glass can survive, but may not work AT ALL with whatever you're trying to do. As an example, deposition of epitaxial silicon on glass will positively destroy any possibility of functionally useful transistors.

So as you refuse to explain what you are trying to do, I can only suggest that you communicate with the suppliers you mentioned.

If you just want a glass check out Vycor.

Possibly Zerodur K20.
