Hi
I need the value of heat transfer coefficient for silicon (MEMS)

Hi

What about looking into the "Handbook of Chemistry and Physics" try section 12-77, of my 86th edition:
crystalline (diamond structure) Si specific heat (@300K) [J/kg/K] = 702,
thermal conductivity (@300K) [mW/cm/K] 1240 ,
density 2.329 [g/cm^3],
thermal expansion (@300K) 2.6 [um/m/K],
section 12-82 you have static dielectric constant 11.9,
index of refraction 3.49 (@589nm)
(funnily no extinction coefficient)

...

Carefull with the special units, this US book is not really SI, and further, for the young modulus get your local coordinate frame correct, in fact I had expeced a few of the items above to also be lattice orientation dependent, maybe not ?

Another way is to Google: thermal properties of Silicone

it would have been quicker (for you) no ?

Have fun
Ivar
