Abstract
Techniques for shielding permittivity-sensitive devices are disclosed.
Claims20
A bioimplantable sensor device shielded against changing permittivity comprising:
- a semiconductor device having an exterior surface with a sensor formed thereon;
- a first layer of metallic adhesive adhered to a portion of the exterior surface of the semiconductor device;
- a layer of permittivity shielding overlying and adhered to the first layer of metallic adhesive;
- a second layer of metallic adhesive overlying and adhered to the layer of permittivity shielding;
- and
- a biocompatible, outermost protective layer overlying and adhered to the second layer of metallic adhesive;
- wherein the first layer of metallic adhesive, the layer of permittivity shielding, and the second layer of metallic adhesive cover the entire exterior surface of the semiconductor device except a part of the surface on which the sensor is formed.
