Claim Text:
1. A manufacturing method, comprising: a) forming a plurality of LED or photovoltaic elemental structures on a first substrate, each of the LED or photovoltaic elemental structures comprising at least one p-type layer, an active zone and an n-type layer; b) forming a planar first metal layer on the elemental structures; c) providing a transfer substrate comprising a planar second metal layer on a surface of the transfer substrate; d) assembling the elemental structures with the transfer substrate by bonding of the first metal layer and the second metal layer, the bonding being carried out by molecular adhesion at room temperature; and e) removing the first substrate; and wherein the elemental structures on the first substrate are spaced apart from each other by trenches; wherein the manufacturing method further comprises depositing an insulating material in the trenches present between the elemental structures between step a) and step b); and wherein step a) further comprises forming each of the elemental structures on an island of relaxed or partially relaxed material.
