Abstract:
A structure may include bond elements having bases joined to conductive elements at a first portion of a first surface and end surfaces remote from the substrate. A dielectric encapsulation element may overlie and extend from the first portion and fill spaces between the bond elements to separate the bond elements from one another. The encapsulation element has a third surface facing away from the first surface. Unencapsulated portions of the bond elements are defined by at least portions of the end surfaces uncovered by the encapsulation element at the third surface. The encapsulation element at least partially defines a second portion of the first surface that is other than the first portion and has an area sized to accommodate an entire area of a microelectronic element. Some conductive elements are at the second portion and configured for connection with such microelectronic element.

Abstract:
A method of manufacturing a wiring board for use in mounting of an electronic component includes: forming an outermost wiring layer on a surface side where the electronic component is mounted; forming an insulating layer so as to cover the wiring layer; and forming a concave portion in the insulating layer. The concave portion is formed by removing, using a mask formed in a required shape by patterning, an exposed portion of the insulating layer in a step-like shape until a surface of a pad defined at a portion of the wiring layer is exposed. The concave portion is preferably formed by removing the portion of the insulating layer by sand blast.
