Claim Text:
1. A high-frequency package comprising: a semiconductor device including a signal source and a conductor pattern that is connected to the signal source; a substrate having a signal line and a ground formed thereon and the semiconductor device mounted thereon; a metal bump for signaling that is formed between the semiconductor device and the substrate, and connects the conductor pattern of the semiconductor device and the signal line of the substrate; first metal bumps for shielding that are formed between the semiconductor device and the substrate so as to be arranged to sandwich the metal bump for signaling, and are connected to the ground of the substrate; and second metal bumps for shielding that are formed in plural between the semiconductor device and the substrate so as to surround the signal source and the conductor pattern with the metal bump for signaling and the first metal bumps for shielding, and are connected to the ground of the substrate, wherein the first metal bumps for shielding and the second metal bumps for shielding are arranged along a circumference of a substantially circular shape that reduces leakage of a high-frequency signal, and the metal bump for signaling is arranged along the circumference of the substantially circular shape, the signal source and the conductor pattern are arranged within the substantially circular shape and not connected to the outside of the circumference through a space between each of the metal bump for signaling, the first metal bumps for shielding and the second metal bumps for shielding, and the space between each of the metal bump for signaling, the first metal bumps for shielding and the second metal bumps for shielding, is equal to or less than half of a wavelength of an electromagnetic wave generated from the signal source.
