Filed: 1995-08-09
Abstract: PROBLEM TO BE SOLVED: To obtain a highly accurate method for metallization by forming a dielectric layer and a titanium nitride layer on a substrate and patterning both layers before titanium nitride and a metal adhere thereto. SOLUTION: A semiconductor, typical in the processing stage, is provided on a substrate 20 and a dielectric layer 32 is formed thereon before planalization takes place. It is then coated with antireflection titanium nitride 34 and both layers 32, 34 are patterned to make an opening. Subsequently, a second titanium nitride layer 44 are formed on the titanium nitride layer 34 and the via or channel. The trench is then filled up and a metal layer 46 of W, for example, is formed while extending onto the titanium nitride layer 44. Consequently, a highly accurate method for metallization is obtained as well as an antireflection film coated directly with a metal and adhesion of metal and dielectric is improved in the dielectric layer.

Title: Minimum pulse width check circuit
Inventor: YASUKI HIROYUKI
IPC: G01R31/28
Filed: 1987-08-17
Abstract: PURPOSE:To detect a defective FF by inputting a test pulse for setting or resetting the FF and varying the phase of the pulse and that of a clock pulse so as to form the contention state and comparing the result with that of a nondefective FF. CONSTITUTION:In inputting a pulse to a clock terminal CLK and a test input terminal RSET 0, a test pulse is given from an output Q of the FF 2 to a FF 1, which is reset. The phase of the clock pulse of the FF 1 and that of the test pulse are varied from this state to form the state where the clock pulse and the test pulse is in contention. Then a check pattern of the output of a nondefective FF when the test pulse is inputted thereto is formed and the pattern is compared with a pattern of the output Q of an FF being an object of inspection. Thus, FFs whose minimum pulse width for setting or resetting is deteriorated are detected and they can be excluded.

Filed: 1982-11-19
Abstract: PURPOSE:To attain an excellent reproducing signal with less storage of a DC error component by constituting a cutoff frequency of an integrator of an input delta modulating signal so as to increase when error bits are numerous. CONSTITUTION:A switch 19 of delta demodulators 13, 14 is connected in parallel with a resistor R1 of a feedback circuit 18, and when the switch 19 is closed, a low-frequency pass band of the circuit 18 is spread, the cutoff frequency functioning as the integrator is increased, and the DC error component caused by the bit error of the delta modulation signal is attenuated rapidly and the quality of the reproducing signal is improved. On the other hand, when the high cutoff frequency of the integrator is increased, since the low-frequency dynamic range of the reproduced analog signal is reduced, the switch 19 is opened for the normal delta modulation transmission so as to ensure the required dynamic range and the excellent reproducing signal is obtained by closing the switch 19 with the transmission where the error rate of the delta modulation is increased.
