Abstract: PROBLEM TO BE SOLVED: To stabilize a voltage-current characteristic by fixing the space between an offset and a contact within a specific range. SOLUTION: A TFT has an offset 54 between the gates 50 and the drain 52. And a space 58 of at least 0.3 μm is secured between a contact region in the drain region and the offset 54. Namely, if the space 58 between the offset 54 and the contact 57 of the drain has a value of at least 0.3 μm, it is possible for the TFT to have 0.2 μm for p region of the drain 52 surely, even if there is an influence of mask dislocation, etc., of about 0.1 μm. Accordingly, it becomes possible to secure each of the source (p-type), gate (n<-> type), offset (n<-> type), and drain (p-type) regions surely. By adopting a constitution like this, it becomes possible to stabilize the voltage-current characteristic of the TFT, and to improve the product characteristic of an electronic apparatus.

CONSTITUTION:A dummy 20 is arranged in parallel to an object 10 to be inspected and has the same material quality as said object 10. The object 10 to be inspected and the dummy 20 has current supply terminals 11, 21 respectively having intervals A, B and probes 13, 23. DC currents are supplied from DC power sources 12, 22 and the potential differences between the probes 13, 23 are measured by voltage measuring devices 14, 24, and outputted to an operation part 31 is inputs by a main voltage measuring device 30 while the operation part 31 detects the generation of a crack in the object 10 to be inspected from the change in potential differences to operate and determine the position and magnitude of the generation of the crack. Because the heat history of the object to be inspected is almost same to that of the dummy and the dummy is not affected by disturbance generated in the object to be inspected, if the potential differences measured by the voltage measuring devices 14, 24 change similarly, the generation of the crack is judged and, if only the potential difference of the measuring device 14 changes, disturbance is judged to be present.

Title: Magnetic head and magnetic recording device using the same
Inventor: MUKAIDE NORIAKI
IPC: G11B5/187
Filed: 1998-03-24
Abstract: PROBLEM TO BE SOLVED: To obtain the magnetic head, in which the error rate is made smaller and the reliability is made higher, by providing recessed shaped glass grooves, which control the track width, on a medium sliding surface along the sliding direction of the medium and making harder for fine dust to stick on the surface. SOLUTION: Two glass grooves 13 are formed in the direction, which is approximately normal to a magnetic gap 12, from the tip of the medium sliding surface to the other tip. The grooves 13 sandwitch the gap 12 and as a result, the track width is controlled. The portion of the surface corresponding to the track width is made of a magnetic material and other portion is made of a nonmagnetic material. By controlling the track width by the grooves 13, the gap between the grooves 13 and 13 becomes the track width. Due to the recessed glass grooves 13, it is difficult for fine dust to stick to the medium sliding surface of a magnetic head 10 and the dust is ejected to the outside through the glass grooves without being remained in the medium sliding surface of the magnetic head.

Abstract: PURPOSE:To enlarge the taper of a wiring metal pattern and then keep coverage on the succeeding insulating film forming process to be in a good condition by performing etching at an inciding angle of 70 deg. or more initially in the case of etching by ion milling of a wiring metal. CONSTITUTION:When etching a wiring metal 2 by ion milling, an inciding angle of an ion beam 4 is set to 75 deg.. Thus, a photoresist pattern 3 has a slight taper on an arc. If the inciding angle exceeds 70 deg. etching is fast on the upper part of the photo resist pattern according to the inciding angle dependency of an etching rate, thus enlarging the taper of the photoresist pattern 3. Therefore, when the wiring metal 2 is etched with the photoresist pattern 3 as a mask. the taper of the wiring metal pattern 5 becomes larger, thus forming a surface protective film 6 on wiring with improved coverage.
