摘要: A method comprises forming elongate structures (5) on a first substrate (3), such that the material composition of each elongate structure (7) varies along its length so as to define first and second physically different sections in the elongate structures. First and second physically different devices (1,2) are then defined in the elongate structures. Alternatively, the first and second physically different sections may be defined in the elongate structures after they have been fabricated. The elongate structures may be encapsulated and transferred to a second substrate (7). The invention provides an improved method for the formation of a circuit structure that requires first and second physically different devices (1,2) to be provided on a common substrate. In particular, only one transfer step is necessary.

摘要: A method of fabricating a device structure, comprises: forming an insulating layer (3b) over a first set of devices disposed over a substrate (3); forming one or more vias in the insulating layer; disposing a second set of devices (6) over the insulating layer, wherein devices of the second set comprise respective electrical contacts (6a) and are disposed over the insulating layer (3b) such that a side on which a contact (6a) can be accessed faces the substrate (3); and forming one or more electrical contacts between the first set of devices and the second set of devices (6) through the via(s). The second set of devices and at least one via are positioned such that one or more of the vias lies at least partially within the footprint of two devices, each belonging to a different device layer.
