Filed: 1996-04-24
Abstract: PROBLEM TO BE SOLVED: To decrease the thickness in the expanded part of a mandrel by dismounting and removing a rear surface helium cooling part and subjecting silicon to plasma removal by an etchant.  
     SOLUTION: A semiconductor device is constituted by forming a gate conductor 11 on a substrate. The conductor is covered with silicon nitride, etc., to form a mandrel polysilicon layer 13. A hard mask oxide layer 18 is formed on the expanded layer 15 and apertures formed in the polysilicon layers 13, 15 are formed. A tungsten stud is applied on the wafer in isotropic silicon etching. The stud has a mask oxide and silicon in contact therewith. The wafer is subjected to rear surface helium cooling, by which the mask oxide is plasma removed at a ratio of argon CF 4 /CHF 3  of 3:1. The rear surface helium cooled part is dismounted and removed and the silicon is plasma removed (peeled) by the etchant. As a result, the loss of the tungsten stud is lessened.
