Title: Semiconductor device
Inventor: HARADA YASUSHI
IPC: H01L23/52
Filed: 1991-10-21
Abstract: PURPOSE:To improve reliability and yield of semiconductor by forging protrusions on a metal wiring. CONSTITUTION:Protrusions 4A are formed in the width direction of a metal wiring 1A which is covered with an interlayer insulating layer and composed of aluminum. Since the tensile stress from the interlayer insulating layer is dispersed by the protrusions 4A, slit type voids are not generated in the metal wiring 1A. Since the tensile stress from the interlayer insulating layer can be dispersed, disconnection of the metal wiring due to the difference of thermal expansion coefficients can be prevented. Thereby the reliability and the yield of a semiconductor device can be improved.

Title: Inverter circuit
Inventor: TOMIOKA ICHIRO
IPC: H03K17/16
Filed: 1987-10-27
Abstract: PURPOSE:To reduce undershoot or ringing by inputting a signal to other N- channel MOSFET via an N-channel MOSFET whose gate receives a positive power voltage and which is normally turned on so as to limit the trailing time. CONSTITUTION:A positive power voltage VDD is given to a gate of an N-channel MOSFET 5, turned on normally and a signal outputted from a node N1 of a CMOS inverter 11 is given to the gate of an N-channel MOSFET 4 via the FET 5. When the potential at a node N3 changes from L to H level, the FET 5 acts on the slow leading of the potential of a node N4 given to the gate of the FET 4. Thus, the FET 4 is conductive slowly and the trailing waveform of an output signal VOUT is slower than a conventional circuit. As a result, undershoot or ringing at the trailing of the output waveform is eliminated or reduced.
