Title: Etching
Inventor: KAWASHIMA KENJI
IPC: H01L21/302
Filed: 1989-05-16
Abstract: PURPOSE:To obtain an etched face of a smoothly recessed shape by a method wherein a thin film having a pinhole is used as a mask. CONSTITUTION:A mask 3 in which a pinhole 2 has been made is installed above, e.g. a GaAs substrate 1 as an object to be etched so as to be separated from the GaAs substrate 1 by a proper length. Then, the mask 3 is irradiated, from its upper part, with a Cl2 plasma as a reactive ion beam. The surface of the GaAs substrate 1 at the lower part is irradiated with the Cl2 plasma which has passed the pinhole 2. Since the mask 3 and the GaAs substrate 1 are installed by keeping a distance, the Cl2 plasma which has passed the pinhole 2 is spread and the surface of the GaAs substrate 1 is irradiated. During this process, the Cl2 plasma is irradiated in such a way that its intensity directly under the pinhole 2 is maximum and that its intensity is lowered gradually by becoming distant from this position. Thereby, it is possible to obtain an etched face 4 which is deep at the center and which forms a smoothly recessed shape in such a way that it becomes shallower progressively further away from the center.

Title: Magneto-resistance effect type head
Inventor: KANAI HITOSHI
IPC: G11B5/39
Filed: 1990-05-11
Abstract: PURPOSE:To suppress the generation of Barkhausen noises and to prevent the fluctuation in output level by impressing the magnetic field similar to the diamagnetic field generated in the magneto-resistance effect type head (MR element) as current magnetic field. CONSTITUTION:The current magnetic field H generated by the current J 19 flowing in a current conductor layer 18 near the MR element 11 is impressed in the easy axis direction of the MR element 11 so as to negate the diamagnetic field. The current magnetic field to be impressed suffices, insofar as this current is larger than the current to negative the diamagnetic field generated in the MR element 11. The magnitude of the current J is adjustable by a power source. The MR head detects the signal magnetic field from a magnetic recording medium 17 moving right thereunder when the MR acts linearly. The MR element 11 has the monodomain structure in this way and does not generate the Barkhausen noises. The fluctuation in the output level of the MR element is averted.
