Disclosed is a multiple separation filter including a microfiltration membrane, an active carbon-based filter and a ceramic filter stacked in order, wherein the active carbon-based filter is obtained by mixing active carbon with at least one selected from zeolite, gold, silver and a mixture thereof, treating the mixture with plasma gas of 60,000\xb0 C. A packet numbering facility assigns to each data packet a data sequence number indicating the correct order for subsequent decoding of encoded data conveyed by that packet. A plurality of package terminals at the second surface are electrically interconnected with the substrate contacts for connecting the package with a component external thereto.
