Methods for Forming Electrically Precise Capacitors, and Structures Formed Therefrom

A capacitor, comprising:

• a. a metal substrate selected from the group consisting of foils and sheets of stainless steel, molybdenum, copper and aluminum, said metal substrate further comprising a barrier layer thereon;
• b. a first insulating layer on said metal substrate, said first insulating layer having a substantially uniform thickness of from 3 Å to 200 Å and a predetermined breakdown voltage;
• c. a first capacitor electrode on said first insulating layer, wherein said first capacitor electrode (i) has an uppermost surface that is smooth and/or curved and a cross-sectional profile, and (ii) is capacitively coupled to said metal substrate;
• d. a second insulating layer on said first capacitor electrode and said first insulating layer;
• and
• e. an antenna on said second insulating layer, electrically connected to said first capacitor electrode and to said metal substrate.
