Drain-Source asymmetry
Mar 04th, 2007, 10:27am
 

I read somewhere that the drain and source of a submicron MOS transistor are not interchangeable because the wafer is angled during an implant. Can someone explain this?

I forgot where I read this. I thought I saw it in Taur + Ning's 'Fundamentals of Modern VLSI Devices', which in my opinion continues to provide the best exposition of submicron device physics for an analog designer.

Vivek, thanks for the link. The entire thread made interesting reading.

Before posting I did try a search for "drain" on the forum's search box (top right), but it didn't return the thread you provided. I will send a note to the forum moderator.
