Claim Text:
1. A resonator assembly comprising: a semiconductor substrate; a resonator gyroscope, the resonator gyroscope including a first resonator formed in a layer of a first material; and an oscillator on the semiconductor substrate, the oscillator including a second resonator formed of a second material; the second resonator being attached in a cavity; the cavity comprising a first recess in said layer of a first material and the edges of the first recess being attached to the substrate, or the cavity comprising a second recess in said substrate and the edges of the second recess being attached to said layer of a first material; said first resonator being formed by etching said layer of a first material after said attaching the edges of the first recess to the substrate or said attaching the edges of the second recess to said layer of a first material; and said cavity being located below a portion of said layer of a first material that is not etched when forming said first resonator.
