Title: Semiconductor device
Inventor: TSUJI SEIICHI
IPC: H01P5/02
Filed: 1989-10-31
Abstract: PURPOSE:To raise the output by chip synthesis without extending the size of a package by setting chips and matching circuit boards on both faces of the package. CONSTITUTION:A high output amplifier consists of a package copper base 1, matching circuit boards 2, chips 3, lead wires 4, Teflon junction parts 5 connecting leads and matching circuits, gold ribbons 6 connecting matching circuits and junction parts, and a gold metallizing film 7. An inputted signal is divided to both of front and rear faces by lead wire junction parts and is amplified on respective faces, and outputs of both faces are synthesized by an output junction part again. Since chips 3 and matching circuit boards 2 are set on both faces of the package and outputs of front and rear faces are synthesized, the double number of chips are synthesized to raise the output without extending the package size.

Title: Magnetoresistance effect element
Inventor: NAMIKATA RYOJI
IPC: H01L43/12
Filed: 1985-12-17
Abstract: PURPOSE:To facilitate formation and to simplify the structure of a thin film magnetic head and the like, by reducing the effect of the roughness of the surface of a basis on the characteristics of a thin film MR element. CONSTITUTION:Especially, a sputtering method, by which a target voltage and a target current are independently controlled, is used. In such a sputtering method, there are more controllable parameters in comparison with an ordinary RF two-pole sputtering method, and the optimum conditions are obtained. Since a substrate does not become an electrode, the element is not exposed to plasma. The element is less restricted by the configuration of a substrate holder. It is especially desirable to use a DC three-pole sputtering method. It is desirable to apply a magnetic field in the desired direction during the sputtering method is carried out. It is desirable that the direction of the magnetic field is perpendicular to the direction of the detected magnetic field of the MR element to be formed. When the magnetic field is applied, uniaxial anisotropy can be induced in the desired direction.
