In the last video about the MOSFET, I showed an image of the fabrication process to make  a transistor on a wafer. Well after awards I was contacted by Dr Henk van Zeijl of the University of Delft University in the Netherlands who teaches fabrication processes. He shared with me a more accurature version of the process which i have included here. And for anyone is interested there is also a link to the dept where he works.

Well, we've done it, 1M subs, I was trying to catch it as it rolled over the 1M mark but I got rather involved in trying to sort out a new audio interface for the computer this afternoon and by the time I'd fixed that and looked again it was 1,000,136. 
But anyway, a big thank you to everyone who has subscribed over the last five and a bit years, here's to two million somewhere around 2026  :-) , thanks once again. 

What would you like to see more videos on? 

The Top Fuel Dragster video is back up again, yay :-) I know a few of you asked what happened, well the issue has been resolved and it's all up and running.
