Use the chemical vapor deposition process given to build a thin layer of metal / dielectric on a silicon wafer.

CVD Gas RXN
SiH4 + 2O2 = SiO2 + 2H2O

Use thermodynamic data from the NIST website kinetics.nist.gov. Determine the temperature and pressure for the production of 100 microns of SiO2 on the silicon substrate.

Select a reactor to carry out the deposition.


Use the following example to calculate mass transfer rates.

First post? Gonna have to offer escrow on it....

I have been doing Microbiology, Thesis papers for business and even a little math; see this posting: https://bitcointalk.org/index.php?topic=1058187.0

But, not going to spend the time to solve this for you without assurance it will be paid. If you will do escrow, let me know

Escrow sounds good. My first time doing this. What service do you use?
A trusted member of the forum to hold the bitcoins until a winner is declared. You'd have to provide him with clear terms to declare the winner too so there's no confusion.

Here's a list:

So we need to find the value of h using the example?

I got h = 0.005. Is it right? I need to find the unit as well now if it's right.
