The surface of the base material may further be coated with an Al2O3 film. The Ti-Al intermetallic compd. can be formed with satisfactory adhesion and the diffusion of Al in the compd. into the Ti or Ti alloy base material in an atmosphere at high temp. can be prevented by the barrier action of the TiN-based layer. Since an Al2O3 film as a dense protective coat can be formed in an oxidizing atmosphere at high temp., a composite material having superior oxidation resistance is obtd.

Abstract: PURPOSE:To improve slip prevention by setting the target throttle opening at the time of the specified slip quantity being generated so as to control the driving torque of an internal combustion engine, and computing the change gear ratio upper limit value necessary for slip prevention at the converged time of the slip so as to set this upper limit value as the target change gear ratio for the control of the actual change gear ratio. CONSTITUTION:An ECU 13 takes in each wheel speed from each wheel speed sensor 16 for driving wheels and driven wheels for comparison. Upon judging the generation of slip over the specified quantity to the driving wheels, the ignition timing is delayed according to the slip quantity to reduce the driving torque of an engine 4, and the opening control of a throttle valve 5 is further combined to suppress the slip. When the slip is converged, the slip limit driving torque is obtained from the engine speed detected by an engine speed sensor 17 and the change gear ratio of a CVT 19 so as to compute the change gear ratio upper limit value necessary for slip prevention in the learning state. In case the target change gear ratio of the CVT 19 set from the vehicle speed and the step-in quantity of an accelerator pedal 14 is over the upper limit value, the upper limit value is set as the target change gear ratio to control the actual change gear ratio.

Title: Alignment method and aligner
Inventor: HASHIMOTO TAKEO
IPC: H01L21/027
Filed: 1997-01-16
Abstract: PROBLEM TO BE SOLVED: To reduce the expanding or shrinking amount of a semiconductor substrate to zero by finding the temperature difference corresponding to the expanding or shrinking amount of the substrate by dividing the measured expanding or shrinking amount of the substrate by the coefficient of thermal expansion of the substrate and heating or cooling the substrate. SOLUTION: After a semiconductor substrate 35 is roughly aligned by measuring the temperature of the substrate 35, the positional deviations of alignment marks at several points on the substrate 35 are measured with a detector 6 and a signal processing unit 5 extracts an expanding or shrinking component and finds the target temperature of the substrate 35 from the expanding or shrinking amount of the component. Then a temperature controller 3 controls the temperature of a fluid and adjusts the temperature of a holder 9 by circulating a fluid to the holder 9. A temperature sensor 2 measures the temperature of the substrate 34 while the substrate 35 is heated or cooled and, when the temperature of the substrate 35 reaches a target value, alignment is started. Consequently, highly accurate in-chip overlay can be performed by correcting the positional deviation of the substrate 35.

Abstract: PURPOSE:To improve the step coverage of an upper layer wiring by a method wherein lower layer wirings having taper parts or convex stepped parts are provided on partial upper layer parts of a laminated layer structure wiring. CONSTITUTION:Lower layer wirings having taper parts or convex stepped parts are provided on at least partial upper layer parts of a laminated layer structure wiring. For example, when the second lower layer wiring conductor 2-2a at lower isotropical etching rate than that of the first and third lower layer wiring conductors 2-1a and 2-3a is laid between said two conductors 2-1a and 2-3a, since the second lower layer conductor 2-2a obstructs the etching process of the first lower layer wiring conductor 2-1a, the lower layer wiring is formed into a taper part with high precision faithfully reflecting a mask size in the wiring. Through these procedures, the ruggedness as it is due to the lower layer wirings will not be reflected in the upper layer wirings thereby enabling the step coverage of the upper layer wiring 6 to be improved.
