摘要:
The present invention provides a connection board that is formed by an insulating resin composition layer made of one layer or two or more layers and a connection conductor that is formed so as to pass through the insulating resin composition layer in its thickness direction at a position where a conductor circuit is connected, and a multi-layer wiring board, a substrate for semiconductor package and a semiconductor package using the connection board, and methods for manufacturing them.

A wiring substrate (1) comprises an insulating base (10) with connection holes (11), buried conductors (12) provided in the connection holes (11) without reaching a rear surface of the insulating base (10), and wiring layers 14 connected to the buried conductors (12). The buried conductors (12) thicken the wiring layers (14), and can form aligning parts (110) on the rear surface of the connection holes (11) to be used for three-dimensional mounting structure. Each wiring layer (14) includes thin terminals (14A), wirings (14B) and thick electrodes (14C). Not only the terminals (14A) and wirings (14B) but also the buried conductors (12) are raised by the same manufacturing process. A semiconductor element (2) is attached to the electrodes (14C) of the wiring substrate (1).

There is provided a wiring board insertion connector having only a small restriction on the structure of a wiring board to be inserted to the connector, having high connection reliability such as high durability against repetitive insertion and pullout, and having a relatively simple structure.The wiring board insertion connector includes: a first substrate; a second substrate; a spacer layer that is located between the first substrate and the second substrate; and openings for accommodating a wiring board at predetermined positions in the spacer layer. The first substrate has a wiring layer, a deformable layer, a rigid layer, and a resin layer formed in this order from the side of the spacer layer. The rigid layer has window portions formed at the regions corresponding to the openings, when seen from a thickness direction of the connector. The wiring layer extends at least to the regions corresponding to the window portions when seen from the thickness direction of the connector, the wiring layer protruding toward opening regions at the window portions.

There is provided a method of manufacturing a concave connector substrate that has high connection accuracy, a low manufacturing cost, and high flexibility in design, can ensure stable repeated use, and significantly improve use convenience.A method of manufacturing a concave connector substrate includes: a step of preparing a guide substrate having a guide/holding region that guides a plate-shaped connector to a connection position and holds the plate-shaped connector at the connection position and a cut portion for removing a section having a shape corresponding to the guide/holding region on at least one side; a step of arranging and aligning two wiring substrates, each having wiring lines and through hole connection portions that are electrically connected to the wiring lines, with both surfaces of the guide substrate, and applying an adhesive to a predetermined region of the guide substrate to bond the wiring substrates to the guide substrate; a step of bending a portion of the wiring substrate toward the inside of the cut portion of the guide substrate and bringing the wiring lines disposed in the bent portion into pressure contact with the inside of the cut portion; and a step of removing a section inside the cut portion to form the guide/holding region.
