I was going to mention this. Stiction was the bane of my effort fabricating even the simplest components as an undergrad. My favorite part was how you can realistically suggest using diamond ablative layers and the like. Made for fun conversations to listen in on - invariably it sounds expensive and high tech, regardless of if it's just sacrificial carbon.

My previous employer was a MEMS sensor company. Let me tell you, stiction really is a huge issue for every single player in the industry.
