I think I am stalled, really stalled on this one! The only other piece of information that describes / models this physical situation would be:
T = To + (Tf - To) e ^(-t/tau).
I know that I am supposed to obtain Tf as the steady state wafer temperature and tau as the time heating...
The boron atoms would collectively carry 100 X 1.602 X 10 ^ -19 J since 1 keV carries 1.602 X 10 ^ -19 J
How many atoms impinging per second is not given, is this something I can calculate from the information that has been provided in the question? If yes, what equation is required?
Thanks.
Homework Statement
A 50mm wafer, 2mm thick is implanted with Boron at 100keV and 1mA. Considering only conductive cooling, given that thermal resistance is 10K/W, to room temperature of 25oC, determine the steady state wafer temperature and also the time constant for heating

1. This is originally a physical problem in semiconductors
2. Problem has been resolved to one equation with decimal powers
3. 1.6x^0.65 - 1.4x^0.2 = 0.2
By inspection, x could easily be 1 but that is not the solution as the value for x is less than 1.
How can I resolve this...
To Mark44, HallsofIvy and other members who helped or looked into my posting, thanks so much!
The good news is I finally resolved the problems and I am so glad I can now move on!
Thank you all for your help so far.
Well, I have used another approach in resolving this this problem but I am wondering if anyone could suggest a way to simplify this further. I wish to express this equation in terms of x:
d = 10^-20 x^(-18/4) x^-1.
So, is there a way to write this equation...
Thanks for your ideas so far.
Well, by squaring it and/or dividing it by 50.12, I am not going to be able to obtain the value of x still which should be in the interval 0.5 < x < 2.5 (from the theory of the physical problem).
The value of w is unknown and the only way of finding it is by...
Homework Statement
The problem is a semiconductor question which I have resolved and gotten the equation:
w = (50.12 x) ^ 0.5
From the knowledge of this system, x is in an interval such that 0.5 < x < 2.5
What mathematical method of solution would help find the solution to this...
