PICK-UP CELLS WITH REDUCED WITHDRAWAL FOR A FRAMEWORK

摘要

A semiconductor device has a transistor and a memory pick-up cell, which are made over a tub in a substrate.The transistor has a first Finn with a first width and two first source/drain elements on the first Finn.The pick-up cell has a second fin with a second width and two second source/drain elements on the second fin.The tub, the first Finn, the second Finn and the second Source/Drain elements have a first type of conductivity.The first source/drain elements have a second conductivity type,which is contrary to the first type of conductivity.The second width is at least three times the first width.The pick-up cell still has a stack of semiconductor layers over the second Finn connecting the two second source/drain elements.
