High Temperature Glass

High Temperature Glass

High Temperature Glass

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

RE: High Temperature Glass

processed how?

CMOS / semiconductor processing - thin film growth and depositions.

RE: High Temperature Glass

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

RE: High Temperature Glass

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.

RE: High Temperature Glass

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 650ÂșC?  That's too low for anything except CVD.

RE: High Temperature Glass

(OP)
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.

RE: High Temperature Glass

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.
