Hi all. A little while ago I overheard my cousin chatting with a friend who works in the semicon industry about the binning process. He was specifically talking about MPU binning techniques in use nowadays and I overheard him mention something to the sound of "boutique line binning". I have no idea what it is, but I only remember scant notes of what he mentioned - something to do with pushing some sort of line (L gate?) further to produce higher FMax bin silicon at the cost of power and expense (usually the expensive models/power consuming by any MPU MFG). I've searched online and not found reference to this anywhere. Can someone explain to me what this is and provide a reference to study about it? Also how is it possible to distinguish if this technique is being used on a CPU, after production by an individual? Are there telltale signs? Thanks for the help.
