Title: Magnetic head slider and its manufacture
Inventor: TANAKA HIDEKAZU
IPC: G11B5/127
Filed: 1997-09-02
Abstract: PROBLEM TO BE SOLVED: To prevent a warp when a residual stress at a film formation process is eliminated by adapting a side face of a magnetic head slider obtained by separating from a substrate after a film is formed on teh substrate as so to be coated with a warp prevention layer of an SiO2 film formed at the film formation process. SOLUTION: An NiFe plating base 9 and a surface layer of a main body layer 4 on an aluminum sacrificial layer 3 formed on a substrate 1 are coated with an SiO2 sputtering film 2'. The SiO2 sputtering film 2' on the upper face of the main body layer 4 and aluminum sacrificial layer 3 is removed by total face ion milling. Subsequently, the NiFe plating base 9 on the aluminum sacrifice layer 3 is removed. A warp prevention layer 2 is left at side face. A horizontal slider fixed on the substrate 1 via the aluminum sacrificial layer 3 is separated from the substrate 1 by etching of the aluminum sacrificial layer 3. Accordingly a warp is prevented and a production yield is improved.

Filed: 1990-09-05
Abstract: PURPOSE:To correctly measure the temperature compensation of IC chips by building in a temperature sensor to measure the temperature of the measured IC chips. CONSTITUTION:A temperature sensor 1 is built in a probe card 2 so as to come into contact with the electrically insulated sections of the surfaces of IC chips 5 in testing the IC chips 5 with the probe card 2. Because the temperature sensor 1 is in contact with the surfaces of the measured IC chips 5, their temperature can be correctly measured when the temperature compensation is measured with an IC wafer testing apparatus. Because the temperature sensor 1 is in contact with the electrically insulated sections of the surfaces of the IC chips 5, it has no effect on measurement of the electric characteristic of the IC chips 5. Thereby the temperature compensation of the IC chips can be measured correctly.
