Classification: CPC H | IPC H

Claim 15:
16. A semiconductor package, comprising:
a first substrate;
a first semiconductor chip mounted on a top surface of the first substrate wherein a first active surface of the first semiconductor chip faces the first substrate;
a second substrate disposed on the first semiconductor chip;
a second semiconductor chip mounted on a bottom surface of the second substrate wherein a second active surface of the second semiconductor chip faces the second substrate; and
wherein an upper portion of the first semiconductor chip and a lower portion of the second semiconductor chip contain an insulating material, the insulating material includes oxygen or nitrogen, the upper portion of the first semiconductor chip includes an oxide, a nitride or an oxynitride of a semiconductor material of the first semiconductor chip, the lower portion of the second semiconductor chip includes an oxide, a nitride or an oxynitride of a semiconductor material of the second semiconductor chip, and a concentration of oxygen or nitrogen in the upper portion of the first semiconductor chip and a concentration of oxygen or nitrogen in the lower portion of the second semiconductor chip decreases with increasing distance from an interface of the first and second semiconductor chips;
an antenna pattern disposed on a top surface of the second substrate,
wherein, at an interface of the first and second semiconductor chips, an upper portion of the first semiconductor chip and a lower portion of the second semiconductor chip constitute one body formed of the same material, wherein the antenna pattern generates broadside radiation and comprises a plurality of patch patterns, and
wherein the antenna pattern is disposed on a top surface of an insulating pattern of the second substrate and is connected to an interconnection pattern disposed in the insulating pattern.
