Congratulations! i have no idea what an oxide is and how this is so exciting but i presume it’s something school related and thus it must be a great success as you must have been working on it for awhile so congratulations on your oxide! yaay! post pics. hahahha
Thanks, it was very important I fabricate a Silicon Dioxide layer with sufficient properties to act as an insulator for my 3-metal layer design on Silicon. I cannot perform the standard thermal oxidation to form Silicon Dioxide because that would bring the temperature of the substrate too high and my metals would melt. So, I had to reactive sputter Silicon Dioxide. In the sputtering process positively charged Argon atoms which are considered heavy are driven towards a target (in my case Silicon) with electric fields. The result of this bombardment is that small molecules from the target fall down on to the substrate upon which you need to deposit the materials. In my case, the gas chamber was filled with Oxygen so that the Silicon debris would react with the Oxygen and fall onto my substrate as Silicon Dioxide. I had been working on this processing step for some time with limited success. I still don’t have a perfect oxide. I do however have an oxide so I know I’m on the right track atleast.

is it cute?
wuts dat? something scientific i suppose. sounds interesting :S
Congratulations!!

that’s amazing. good for you!
Mashallah! I am so proud of you!
Guess what now we have a new oxide : N2O (Nusraat Oxide)
