Inventor: HOSOI YOSHIHIRO
IPC: H01L21/52
Filed: 1985-07-30
Abstract: PURPOSE:To form thinner conductive layers of gold, to contrive to cut down the cost of electronic parts and to enable to maintain the same efficiency as that of a conventional one by providing metal layers consisting of platinum of specific thickness at the bases of the conductive layers of gold. CONSTITUTION:0.05mum or more thick metal layers 6 and 7 consisting of platinum are provided as the bases of the conductive layers 8 and 9 of gold of an electronic parts having the conductive layers 8 and 9 of gold. When the metal layers 6 and 7 consisting of platinum are provided as the bases of the conductive layers 8 and 9 of gold in such a manner, even though a wire or a semiconductor chip is exposed at high temperature when being attached to a wire bonding part or to a die attaching part, nickel and gold are effectively prevented from diffusing in the metal layers consisting of platinum since platinum is a metal which hardly allows a diffusion of gold and is higher in melting point compared to palladium and the conductive layers of gold can be firmly bonded on the metallized metal surfaces. The layer thicknesses of the conductive layers 6 and 7 of gold can be formed thinner and the cost of a ceramic package for housing a semiconductor can be significantly reduced.

Title: Noise reduction circuit
Inventor: YAMAMOTO TAKESHI
IPC: H03G7/00
Filed: 1990-06-29
Abstract: PURPOSE:To improve the distortion of an output signal without deteriorating the tracking performance against a rapid increase in the signal amplitude by selecting a larger attack time in a normal state and switching it to the smaller attack time when the amplitude of a signal fed to a gain control amplifier is suddenly changed. CONSTITUTION:A time constant circuit consists of a capacitor C1 constituting a detection filter and resistors R1-R3 to decide the attack time and the recover time. Then the large attack time is selected in the normal state to detect a sudden amplitude change in a signal fed to a gain control control means 15 and then the shorter time constant of the time constant circuit is selected, thereby shortening the attack time. Thus, the distortion in an output signal is improved without deteriorating the tracking performance against a sudden change in the signal amplitude.
