An electronic part embedded substrate is disclosed. The electronic part embedded substrate includes a first substrate, a second substrate, an electronic part, an electrically connecting member, and a sealing member. A method of producing an electronic part embedded substrate is also disclosed. The method includes mounting an electronic part onto a first substrate, laminating a second substrate on the first substrate through an electrically connecting member; and filling a space between the first substrate and the second substrate with a sealing member to seal the electronic part.

Electronic part embedded substrate and method of producing an electronic part embedded substrate

Chip embedded substrate and method of producing the same

A method of producing a chip embedded substrate is disclosed. This method comprises a first step of mounting a semiconductor chip on a first substrate on which a first wiring is formed; and a second step of joining the first substrate with a second substrate on which a second wiring is formed. In the second step, the semiconductor chip is encapsulated between the first substrate and the second substrate and electrical connection is made between the first wiring and the second wiring so as to form multilayered wirings connected to the semiconductor chip.

A bonding tool holds a lower chip against a release tape held by a suction force. The bonding tool has an electronic-component suction opening against which the lower chip is held and, surrounding the electronic-component suction opening, a trench that accommodates the release tape. The lower chip is heated, by being pressed against an underfill material and, thus, an area on which an upper chip is mounted is formed in such a manner that the underfill material protrudes out from the lower chip. During the heating, because an expanded part of the release tape, expanded due to heat, is inserted into the trench, no folded line is formed on the upper surface of the underfill material.
