Patent ID: 7273474

Claim:
A method of fabricating a flexible substrate structure for microneedle arrays, which comprises the steps of: a) implanting ions on a tip, a sidewall, and a predetermined portion of a base of a tapered shape object to produce an ion implanted area of the tapered shape object, the side wall is located adjacent to the tip and the base; b) applying a flexible substrate on a lower part of a surface of the sidewall and a top surface of the base, the flexible substrate extending around a periphery of the sidewall; c) removing a portion of the base surrounding the ion implanted area utilizing an etching process to produce the flexible substrate structure having the flexible substrate connected to a top surface of the predetermined portion of the base and the lower portion of the sidewall, the ions located in the ion implanted area of the tapered shape object preventing etching of the ion implanted area during the etching process.
