Abstract:
1. A circuit assembly comprising: a support structure including a first contact pad disposed on an upper surface thereof, said first contact pad being electrically connected to at least one conductor disposed on said support structure; an integrated circuit (IC) device mounted on the support structure such that a non-active surface of the IC device faces away from the support structure, and an active surface of the IC device faces the upper surface of the support structure, the IC device including a second contact pad that is disposed on the active surface and is electrically connected to at least one conductive structure disposed on said IC device; a curved micro-spring disposed in an air gap region defined between the upper surface of the support structure and the active surface of the IC device, the micro-spring including a first end that is electrically connected to the second contact pad, a second end that is electrically connected to the first contact pad, and a curved body portion extending between the first and second ends; and a plurality of ribbon bonds, each said ribbon bond having a first end portion connected to the upper surface of the support structure, a second end portion connected to the second surface of the IC device, and a body portion extending between the first and second end portions, whereby the IC device is mechanically secured to the support structure by said ribbon bonds.
