Filed: 1998-01-16
Abstract: PROBLEM TO BE SOLVED: To significantly reduce the manufacturing cost for a stator and enhance the efficiency of a motor, by immersing a cylindrical core in molten insulating agent to form a film composed of the insulating agent on the surface of the cylindrical core. SOLUTION: A core 3 is immersed in a molten insulating agent 21, such as polyimide, epoxy, stored in a bath 2, and a film composed of the insulating agent 21 is thereby formed on the surface of the core 3. Since an insulating film is thus formed on the inner surfaces of slots 4, an insulating film for providing insulation between windings and a core is obviated, and cost therefor, trouble and time required for placing such an insulating film can be saved. Therefore, the manufacturing cost for a stator can be significantly reduced. In addition, the number of windings in the slots 4, that is, space factor, is increased, and thus the efficiency of the motor is enhanced. When the motor is housed in the sealed housing of a hermetically sealed compressor, current leaking from the circumference of the core 3 to the sealed housing can be reduced.

Abstract: PURPOSE:To prevent a short-circuit between a semiconductor device and a wiring layer by forming an insulating film on the surface of a scribing line region. CONSTITUTION:As a flip chip semiconductor device can be actuated in a low voltage of about 1V, a short-circuit between the device and the wiring layer can be prevented if an oxide film 11 is remained by 200-1,000Angstrom  or thereabouts. A solder film 5 is formed in such a way as to cover a Cr-Cu-Au film 4 and thereafter, when the wafer is heated, the solder film is formed into a solder ball 6' on the Cr-Cu-Au film 4 by its surface tension. At this time, an excess solder ball 8' is easy to leave on a scribing line region 7. When this flip chip semiconductor device is mounted on the printed substrate, the solder ball 8' on the scribing line region 7 comes to contact to the solder ball 6' on the Cr-Cu- Au film 4 and the solder ball 8' and the printed substrate come to such a state that they are electrically connected to each other, but the solder ball 8' is electrically insulated from an Si substrate 1 because the oxide film 11 is ready-formed on the surface of the scribing line region 7. Therefore, the printed substrate and the Si substrate are not short-circuited.
