Abstract: A multi-component transistor structure includes components each comprising an individual, discrete, and separate component substrate and a component transistor. The component transistor includes a transistor element having a transistor element resistance. A component connection is disposed external to the transistor element and has a connection resistance. The component connection electrically connects the transistor elements in the components in parallel. The connection resistance is less than the transistor element resistance of at least one corresponding transistor element, less than an average of the transistor element resistances of all of the corresponding transistor elements, or less than the sum of all of the transistor element resistances of all of the corresponding transistor elements. The component transistors are functionally similar and at least one of the components is disposed on another different one of the components in a component stack.

Abstract: An example of a cavity structure comprises a cavity substrate comprising a substrate surface, a cavity extending into the cavity substrate, the cavity having a cavity bottom and cavity walls, and a cap disposed on a side of the cavity opposite the cavity bottom. The cavity substrate, the cap, and the one or more cavity walls form a cavity enclosing a volume. A component can be disposed in the cavity and can extend above the substrate surface. The component can be a piezoelectric or a MEMS device. The cap can have a tophat configuration. The cavity structure can be micro-transfer printed from a source wafer to a destination substrate.

Abstract: A micro-optical structure includes a structure substrate comprising a cavity and a micro-optical component disposed entirely and directly over or in the cavity. The micro-optical component includes a micro-optical element and a component tether physically attached to an anchor portion of the structure substrate and in contact with the micro-optical element. The structure substrate and the micro-optical component can be monolithic, for example unitary and comprise a same material or are the same material. The micro-optical component can be disposed on a sacrificial portion disposed on a micro-optical component source wafer differentially etchable form the sacrificial portion. The micro-optical component can be disposed on a micro-optical component source wafer patterned with an encapsulation layer where the micro-optical component is differentially etchable from the encapsulation layer and the micro-optical component.

Abstract: A micro-optical component includes a micro-substrate, a micro-optical element disposed on the micro-substrate, and a stand-off (a mechanical spacer) disposed on the micro-substrate or micro-optical component in a separate plane from the micro-substrate that at least partially encloses the micro-optical element. The micro-optical components can be stacked on a system substrate using micro-transfer printing to form a three-dimensional micro-optical structure. One more light beams can travel or pass through various combinations of multiple micro-optical components and micro-optical elements.

Abstract: A micro-component comprises a component substrate having a first side and an opposing second side. Fenders project from the first and second sides of the component substrate and include first-side fenders extending from the first side and a second-side fender extending from the second side of the component substrate. At least two of the first-side fenders have a non-conductive surface and are disposed closer to a corner of the component substrate than to a center of the component substrate.

Abstract: A hybrid document includes a flexible document having visible markings. One or more light-controlling elements and a controller are embedded in or on the flexible document. The controller is electrically connected to the one or more light-controlling elements to control the one or more light-controlling elements. A power input connection is electrically connected to the controller, or one or more light-controlling elements, or both. A power source can be connected to the power input connection, for example a piezoelectric or photovoltaic power source. In response to applied power, the controller causes the one or more light-controlling elements to emit light. In some embodiments, the controller includes a memory and a value can be stored in the memory and displayed by the light-controlling element(s). In some embodiments, the value can be assigned or varied by a hybrid currency teller machine.
