Abstract
A double-sided electronic device includes a heat conductive substrate having working zones of structures and components disposed thereon in double planar arrangement, as a monolithic or hybrid electronic device. In order to connect the structures or components, disposed on different sides of a substrate, connecting conductors go through the substrate's edges. At the same time the connecting conductors are insulated from the structures and pass on main surfaces of double-sided electronic device. In a case of failure detection after burn-in and checking, the device having one good side is used as conventional, housed in a package or three-dimensional module. A device having two good surfaces has double information capacity. The invention provides a large economic benefit due to economy of materials and significantly increases a packing density of electronic equipment.
