3D integrated circuit packages with window interposers and methods to form such semiconductor packages are described. The particular feature of the inflatable cuff is a number of local bulges distributed along the circumference of the cuff. Air is sent to the air motor 740 from an air source 551b by switching a valve, and an assist gas for a normal or reverse rotation is sent from an assist gas source 554b to the upper portion of the piston member 730, so that a tap is lowered to perform tapping to a work.
