  • Patent number: 11916456
    Abstract: A connection structure of a stator of a drive motor is configured to allow coils to be wound in a plurality of slots provided in a stator core and to connect the coils withdrawn from the slots. The coils are wound in the slots to form first-type structures and second-type structures configured such that withdrawal directions of three-phase (U-, W- and V-phase) withdrawal lines and N-phase withdrawal lines withdrawn from the slots of the first-type structures are opposite to withdrawal directions of three-phase (U-, W- and V-phase) withdrawal lines and N-phase withdrawal lines withdrawn from the slots of the second-type structures. The first-type structures and the second-type structures are disposed symmetrically to each other with respect to a reference line formed to divide the slots in half.

  • Patent number: 7211488
    Abstract: The present invention relates to a method of forming an interlayer dielectric film in a semiconductor device. More particularly, the present invention selectively forms an insulating film spacer only at a region where a plug is formed between metal lines and removes the insulating film spacer at a region where the plug is not formed to lower the aspect ratio between the metal lines, in a process of burying an insulating material between the metal lines to electrically insulate them. Therefore, the present invention can easily bury the insulating material even between the metal lines having a narrow gap without voids.
