Title: Semiconductor device and fabrication thereof
Inventor: ANDO TAKESHI
IPC: H01L21/265
Filed: 1997-01-20
Abstract: PROBLEM TO BE SOLVED: To suppress titanium silicide from creeping up on an insulator side wall by forming a gate electrode and coating it entirely with the insulator, implanting nitrogen ions from an oblique direction and then etching the insulator anisotropically thereby forming an insulator side wall containing nitrogen on the side face of the gate electrode. SOLUTION: A gate electrode 3 is formed and coated entirely with an oxide 4 which is then implanted with nitrogen ions from an oblique direction. Subsequently, the oxide 4 is subjected to anisotropic etching to form an oxide side wall 5 containing nitrogen on the side face of the gate electrode 3. Consequently, nitrogen spreads into titanium 7 abutting on the oxide side wall 5 from the inside when a titanium silicide layer 8 is formed by causing reaction among the titanium 7 deposited on the entire surface, the gate electrode 3 and a source- drain diffusion layer 6 through heat treatment. This method suppresses creeping up of titanium silicide onto the oxide side wall 5.

Title: Exhaust emission control device for internal combustion engine
Inventor: TAYAMA AKIRA
IPC: F01N3/28
Filed: 1999-01-14
Abstract: PROBLEM TO BE SOLVED: To surely reduce and control exhaust emission when NOx absorbed during a lean operation is discharged by rich spike. SOLUTION: A first catalyst 3 for emission control which can absorbs NOx is disposed in an exhaust passage 2 of internal combustion engine 1, a second catalyst 4 whose oxygen absorbing function is small is disposed more downstream than the first catalyst 3 in the exhaust passage 2, and a third catalyst 5 whose oxygen absorbing function is large is disposed more downstream than the second catalyst 4 in the exhaust passage 2. When an NOx absorbing amount reaches a certain value, an air fuel ratio is forced to be excessively rich, and desorption of absorbed NOx is carried out. Most of NOx desorbed and discharged is subjected to emission control on the first catalyst 3 for emission control, and the NOx which is not reduced in this step is reduced on the second catalyst 4.  Since the oxygen absorbing function of the second catalyst 4 is made small, NOx is efficiently reduced independent of affection of discharge of oxygen. Further, NOx is surely reduced by being excessively rich state. Excess reduction component which is not used at the time of reducing of NOx is subjected to emission control on the third catalyst 5 having the oxygen absorbing function.
