Abstract: A overhanging device cavity structure comprises a substrate and a cavity disposed in or on the substrate. The cavity comprises a first cavity side wall and a second cavity side wall opposing the first cavity side wall on an opposite side of the cavity from the first cavity side wall. A support extends from the first cavity side wall to the second cavity side wall and at least partially divides the cavity. A device is disposed on, for example in direct contact with, the support and extends from the support into the cavity.

Abstract: A method of assembling components includes the steps of providing a stamp, providing a component disposed on an adhesive surface, pressing the stamp against the component to adhere the component to the stamp, pulling the stamp away from the adhesive surface, and removing the component from the adhesive surface with the stamp. The adhesive surface can deform in a direction of the stamp and can enable progressive delamination of the adhesive surface from a bottom of the component from an edge or corner of the component toward a center of the component, thereby reducing the instantaneous adhesive force between the component and at least a portion of the adhesive surface. The method can enable the transfer and assembly of many millions of small and fragile components per hour with excellent precision from a tape to a target substrate.

Abstract: A component structure comprises a substrate and a sacrificial layer comprising a sacrificial material disposed on or in the substrate. The sacrificial layer defines sacrificial portions laterally spaced apart by anchors. A component is disposed entirely over each sacrificial portion and connected to at least one anchor by a tether. A spacer comprising a spacer material is disposed in or on the sacrificial portion at least partially between the tether and the substrate. For at least one etchant, the spacer material etches faster than the sacrificial material when exposed to the etchant.
