Abstract:
An IC (Integrated Circuit) package having a package body, the package body comprising:a first generally flat, electrically insulating layer having a first generally rectangular hole defined by four first edges in a middle of the first insulating layer; a second generally flat, electrically insulating layer having a second generally rectangular hole defined by four second edges in a middle of the second insulating layer to generally be aligned with the first insulating layer, the second insulating layer having a primary surface on which the first insulating layer is formed; and a third generally flat, electrically insulating layer having a primary surface on which the second insulating layer is formed, the first and second holes defining a cavity in the first and second insulating layers for receiving an IC chip; a discrete device the second hole being smaller in plan view than the first hole so that at least a portion of the first edges is set back from a corresponding part of the second edges to form a terrace of the second insulating layer, the second insulating layer terrace extending toward the cavity, and mounting the discrete device thereon; and a first and a second electrically conductive pattern being formed within the cavity on a primary surface of the first insulating layer that does not face the primary surface of the second insulating layer; a generally flat cap hermetically sealing the cavity such that the discrete device, first and second conductive patterns and the first and second insulating layers are within the cavity between the cap and the third insulating layer the first conductive pattern including control signal lines assigned to the IC chip and adjoining at least one of the four first edges; the second conductive pattern including signal lines other than the control signal lines assigned to the IC chip and adjoining at least one edge among the four first edges not adjoining the control signal lines; wherein the control signal lines adjoin two of the four first edges opposing each other with respect to the cavity, the signal lines other than the control signal lines adjoining the remaining two of the four first edges.
