I am currently working on the packaging attenuator chip. I would like to =
know the
-young modulus
-thermal expansion coefficient
-poisson ratio

of silicon,  fiber glass, silicon oxide.  Is there any change in thermal =
expansian coefficient if these material is coated by metal such as =
Chrome, and gold

Thanks.
Best regards
Hao Pham
