Abstract
Abstract The present invention teaches a method of manufacturing a enclosed transceiver, such as a radio frequency identification ("RFID") tag. Structurally, in one embodiment, the tag comprises an integrated circuit (IC) chip, and an RF antenna mounted on a thin film substrate powered by a thin film battery. A variety of antenna geometries are compatible with the above tag construction. These include monopole antennas, dipole antennas, dual dipole antennas, a combination of dipole and loop antennas. Further, in another embodiment, the antennas are positioned either within the plane of the thin film battery or superjacent to the thin film battery.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
84 words
A method of manufacturing a radio frequency identification (RFID) transceiver, comprising the steps of: providing two covers, each cover being composed of a sheet of polymer film; depositing on each of the two covers a barrier material which is a barrier to water vapor; mounting an RFID transceiver circuit and a battery between the two covers; and sealing the two covers together along a peripheral contour which completely encircles the transceiver and battery; whereby the barrier material protects the battery and transceiver from contamination.
Claim 2
Independent Claim
84 words
A method of manufacturing a radio frequency identification (RFID) transceiver, comprising the steps of: providing two covers, each cover being composed of a sheet of polymer film; depositing on each of the two covers a barrier material which is a barrier to water vapor; mounting an RFID transceiver circuit and a battery between the two covers; and sealing the two covers together along a peripheral contour which completely encircles the transceiver and battery; whereby the barrier material protects the battery and transceiver from contamination.
Claim 3
Dependent Claim
23 words
A method according to claim 1, further comprising the step of mounting between the two covers an antenna connected to the RFID transceiver.
Claim 4
Dependent Claim
24 words
A method according to claim 1, wherein the depositing step comprises depositing the barrier material by sputter deposition, chemical vapor deposition, or evaporation deposition.
Claim 5
Dependent Claim
28 words
A method according to claim 1, wherein the depositing step comprises depositing as the barrier material a substance from the set consisting of silicon oxide and silicon nitride.
Claim 6
Dependent Claim
27 words
A method according to claim 1, wherein the depositing step comprises depositing as the barrier material a substance from the set consisting of polyethylene and polyvinylidenechloride (PVDC).
Claim 7
Dependent Claim
18 words
A method according to claim 1, wherein the depositing step comprises depositing as the barrier material a fluorohalocarbon.
Claim 8
Dependent Claim
11 words
A method according to claim 6, wherein the fluorohalocarbon is perchlorotetrafluoroethylene.
Claim 9
Dependent Claim
23 words
A method according to claim 1, wherein the depositing step comprises depositing the barrier material in a thickness of 400 to 10,000 angstroms.
Claim 10
Dependent Claim
26 words
A method according to claim 1, wherein the depositing step comprises depositing the barrier material on both sides of at least one of the two covers.
Claim 11
Dependent Claim
28 words
A method according to claim 9, wherein the depositing step further comprises depositing the barrier material on said both sides in a thickness of 100 to 400 angstroms.
