摘要:
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.

In a method of removing conductive balls that are left on a mask provided on a substrate having pads thereon, the method includes: (a) making a sheet member close to the mask using a contacting mechanism such that a gap between the sheet member and the mask is set small than a diameter of the conductive balls. The conductive balls are removed in such a manner that the conductive balls are adhered onto the sheet member.

A method of mounting conductive balls on pads on a substrate includes: (a) placing the substrate having the pads coated with an adhesive over a container for containing the conductive balls therein and whose top surface is open such that the pads faces the top surface of the container; and (b) throwing up the conductive balls in the container by moving the container up and down at a given stroke, thereby allowing the conductive balls to adhere to the adhesive coated on the pads. Step (b) is repeatedly performed.
