Title: Pulse noise correcting circuit
Inventor: IZAWA KAORU
IPC: G11B20/02
Filed: 1989-07-12
Abstract: PURPOSE:To always realize satisfactory correction by controlling the feedback quantity of a signal feedback path by an output from the level detector of a noise reduction decode circuit to which suitable weighing is applied so as to increase a relative level in a high area frequency. CONSTITUTION:The feedback quantity of a signal feedback path 4 is controlled by a control signal corresponding to the output from a level detector 11a of a noise reduction decode circuit 6, to which weighing is applied so as to increase the relative level in the high area frequency, and inclination at the time of hold is changed corresponding to a signal frequency and a signal level. Accordingly, since the signal feedback quantity for differential hold correction is enough enlarged in a place where the frequency and level of an audio signal are high, the inclination of a corrected waveform is enlarged and since the feedback is limited in a place where the frequency and level are reversely low, the inclination of the corrected waveform is made smooth and close to preceding-value hold correction. Thus, the correction can be executed to be matched with respective signal states.

Abstract: PURPOSE:To bury a via hole without resulting in an excess Al/Si reaction and the breakdown of a lower-layer Al wiring by setting the pulse width of pulse laser beams at 100 or less and projecting pulse laser beams. CONSTITUTION:A laser such as an excimer laser of ArF (a wavelength lambda=193nm) is used as pulse laser beams 4 projected from the upper section of Al 3, and pulse width thereof is set at a comparatively short order of 100ns or less. Af 3 is melted by the projection of the pulse laser beams 4, and the inside of a via hole 2a is buried uniformly with Al 3 and an Af layer 3a is formed. An Si layer reacts only in depth up to 0.3mum at the most by the pulse laser 4 so far as pulse width of 100ns or less is projected. Accordingly, an excess Al/Si reaction displaying junction breakdown in a contact section with an Si substrate 1 is not induced, and the irradiation time is shortened, thus preventing the thermal breakdown of a lower-layer Al wiring even when the method is applied for multilayer Al interconnection structure.
