IPC: H01L21/768
Filed: 2002-03-07
Abstract: PROBLEM TO BE SOLVED: To provide a method for fabricating a semiconductor device in which fine patterning can be used while eliminating short-circuiting of a gate electrode and a contact member. SOLUTION: A gate insulation film 2, a gate electrode 3a and a protective layer 4a are formed on an Si substrate 1 and followed by formation of a lightly doped source-drain region 6. A first sidewall 15a and a second sidewall are formed on the side face of the gate electrode 3a and used as a mask for forming a heavily doped source-drain region 9 by ion implantation. After the second sidewall 16a is removed selectively, a pocket implantation region Rpo is formed and a protective film 12 is deposited on the entire surface. Subsequently, an interlayer insulation film 10 is deposited, a contact hole Hct reaching the heavily doped source-drain region 9 is made and a plug electrode 11 is formed. Since the second sidewall is removed t the time of depositing the protective film 12 on the entire surface, the gap between the gate electrodes 3 is not filled.

Abstract: <P>PROBLEM TO BE SOLVED: To control a laser output in forming a pit in real time.  <P>SOLUTION: At recording the optical disk, return light receiving signals E, F of a sub-beam 16b are added by an adding amplifier 34 to obtain E+F. A level of E+F in forming the pit is subjected to sample-and-hold to a sample- hold circuit 36, and the level of E+F at the pit non-forming time is subjected to sample-and-hold to a sample-hold circuit 37. The difference α-β between an average value α of the sample-hold value of E+F in forming the pit and an average value β of the sample-hold value of E+F at the pit non-forming time is obtained by a subtraction circuit 40. The deviation between a reference value α<SB>0</SB>-β<SB>0</SB>of α-β being set on a reference value setting circuit 44 and the obtained value of α-β is obtained by a comparator 48. By a laser output control circuit 50, an output of the laser beam in forming the pit is increased/ decreased by a laser output control circuit 50 so as to negate this deviation.  <P>COPYRIGHT: (C)2003,JPO
