Hello, I have a test tomorrow, I have steps about process and the final junction.
here are the steps,
Thermal Oxidation
N+ diffusion mask
Oxide Etch
N+ diffusion and oxidation
contact opening mask
oxide etch
Metal Deposition
Metal etch mask
Metallization etch
picture looks, there are 3 oxide layers there are same size space at the end and beginning of the layers . under the first space, there is n-well and on the same space there is AL with N contact, and on the second space there is AL with P contact.
Can someone explain me the steps what they do regarding to final picture that I tried to explain ?
