Most people call it "hilling" the potatoes but I don't think I'd call that a "technical" term.
12" is a great time to hill them up for the first time. And definitely do NOT cover the entire plant! You want to leave plenty of leaves above ground so they keep growing (I never cover more than 50% of the above ground vine). Ideally you hill them 3-5 times before they flower, then stop hilling, wait for the vines to die back, then dig up your potatoes!
