Filed: 1996-06-05
Abstract: PROBLEM TO BE SOLVED: To improve an acceleration feeling when an accelerator is stepped on at a stroke during traveling so as to accelerate again, by controlling rise time of clutch current when an electromagnetic powder clutch is engaged again, to an appropriate time value per vehicle speed. SOLUTION: Attention is paid to such a point that time required for blowing up an engine 1 is different between a case that an accelerator is stepped on at a stroke so as to accelerate again when a vehicle is traveled at a low speed and a case that the accelerator is stepped on at a stroke so as to accelerate again when the vehicle is traveled at a high speed, and in an exclusive map, relation between such a vehicle speed and rise time of clutch current is previously recorded in data and mapped.  Then, the raise time of the clutch current supplied to an electromagnetic powder clutch 2 is controlled by the rise time of the clutch current read out of such a kick down exclusive map, therefore the shift down time of a continuously variable transmission and time when the electromagnetic powder clutch 2 is completed to be fastened again, are matched to each other, and the engine 1 is sufficiently raised, and adapted to the vehicle speed so as to obtain an accelerating feeling.

Title: Manufacture of semiconductor integrated circuit
Inventor: FUJITA TSUTOMU
IPC: H01L23/52
Filed: 1987-07-03
Abstract: PURPOSE:To prevent the formation of non-conductive substances on Al interconnections and lower contact resistance between the interconnections by forming silicon on the whole surface of a substrate and also by forming an interconnection pattern after depositing Al on the whole surface and then, by making gases which contain metals react, thereby coating the Al interconnections with metals selectively. CONSTITUTION:An insulating film 2 is formed on a semiconductor substrate 1 and then an Al film 3 and a silicon film 4 are deposited on the above substrate continuously. As, in such a case, the Al upper surface 3 does not come into contact with an atmosphere of oxygen, the silicon film 4 is deposited in a state where an alumina film is not formed on the Al surface 3. Then, an interconnection pattern is formed. After that, tungsten 5 is selectively deposited only on silicon 4 through silicon reducing reaction of WF6. Thereupon, contact is completely made between tungsten 5 and Al without producing non-conductive aluminum fluoride at its interface. This approach prevents electro-migration as well as stress migration which involve problems to be solved in the field of interconnection and lowers contact resistance between the interconnecitons.
