Abstract:
1. A chip-level through hole structure of electronic package, comprising: a radio frequency (RF) passage defined on a wafer and penetrating there-through; a first through hole structure comprising a plurality of discrete through-vias arranged in a circular pattern about the RF passage, each through-via penetrating through the wafer and electrically insulted from the radio frequency passage and from each other; and a second through hole structure comprising a plurality pairs of discrete through holes disposed around the RF passage and arranged between the RF passage and the through-vias of the first through hole structure, each through hole penetrating through the wafer and electrically insulated from the RF passage, the first through hole structure, and from each other; wherein the through hole structures substantially isolate the radio frequency passage thereinside and define an electric reference plane for preventing a signal transmitted inside the radio frequency passage from decaying and interference.
