WIRING CORE STRUCTURE, SEMICONDUCTOR EVALUATION DEVICE AND SEMICONDUCTOR DEVICE
First Claim
1. A wiring core structure comprising:
- a tubular-shaped core portion having a wiring hole for passage of a main wire to be a parasitic-inductance suppression target and having a body portion made of a soft magnetic material; and
a wound wire formed by winding a wire around said core portion and having both ends short-circuited, whereinsaid core portion includes a plurality of divided core portions which are disposed in a superposed relation and each have a wiring hole, andsaid plurality of divided core portions are formed such that shapes of said wiring holes and outside diameters of said body portions are different from each other, thereby implementing a superposition structure without overlapping in plan view.

Abstract
A wound wire is wound around a core assembly so that both ends are short-circuited. In a coupling pin insertion state in which a coupling pin is inserted in a through hole of the core assembly, outer-peripheral space parts of respective divided core portions of the core assembly are disposed so as to overlap in plan view. Consequently, an air gap is formed in a part of a side surface of the core assembly. Before formation of a covering member, a main wire is caused to pass through the air gap and is thus disposed in a wiring hole of the core assembly. Then, the covering member for closing the air gap is provided on an outer peripheral surface side of the core assembly including the air gap so that a core structure is obtained.

3. A wiring core structure comprising:
-
a tubular-shaped core portion having a wiring hole for passage of a main wire to be a parasitic-inductance suppression target and having a body portion made of a soft magnetic material; and a wound wire formed by winding a wire around said core portion and having both ends short-circuited, wherein said core portion includes a plurality of divided core portions which are stacked on one another and disposed, and have identical planar shapes, each of said plurality of divided core portions includes; an outer-peripheral space part, provided in said body portion, for inserting said main wire into said wiring hole at a side-surface side of said body portion; and a through hole, provided on said body portion, for causing a common coupling pin to penetrate through said plurality of divided core portions, and in a coupling pin insertion state in which said coupling pin is inserted into said through hole provided in said plurality of divided core portions, said divided core portions have a closing structure that prevents said main wire from being removed toward an outside of said wiring hole through said outer-peripheral space part. - View Dependent Claims (4, 5, 6, 7, 8)
