Classification: CPC B | IPC B

Claim 0:
1. A package for a microfluidic device, comprising
first low-temperature co-fired ceramic (LTCC) green tape layers having openings of pre-determined sizes and shapes made through the first LTCC layers according to pre-determined patterns;
second LTCC green tape layers having pre-defined openings that are selectively filled with an electrically conductive material to form vertical electrical connection pathways through the second LTCC green tape layers;
third LTCC green tape layers having pre-determined electrical connections made with an electrically conductive material deposited onto the surfaces of the third LTCC green tape layers to form horizontal electrical connection pathways across the third LTCC green tape layers;
fourth LTCC green tape layers having pre-determined types and sizes of passive electrical components made with an electrically conductive material onto the surfaces of the fourth LTCC green tape layers;
fifth LTCC green tape layers having pre-determined features of openings made through a thickness of the fifth LTCC green tape layers to partially form portions of a fluid handling channels;
sixth LTCC green tape layers having pre-determined open features made through a thickness of the sixth LTCC green tape layers to form fluidic inlet and outlet ports;
seventh LTCC green tape layers having pre-determined features of materials patterned on the surfaces of the seventh LTCC green tape layers to facilitate bonding,
wherein two or more of the first to seventh LTCC green tape layers are aligned and stacked to form a first packaging module based on being exposed to an elevated temperature to transition the LTCC green tape of the first packaging module to a stable form of LTCC ceramic material,
wherein two or more of the first to seventh LTCC green tape layers are aligned and stacked to form a second packaging module based on being exposed to the elevated temperature to transition the LTCC green tape of the second packaging module to a stable form of LTCC ceramic material,
one or more device dies is disposed onto pre-determined surfaces within the first packaging module and/or the second packaging module, and
the one or more pre-determined surfaces of the first packaging module is bonded to one or more surfaces of the second packaging module to form an encapsulated and sealed package enclosure for the one or more device dies.
