摘要
A method for manufacturing a substrate comprising the following steps of: providing a stack comprising an initial substrate, a GaN layer, a doped InGaN layer and an unintentionally doped InGaN layer, transferring the doped InGaN layer and the unintentionally doped InGaN layer to an anodising support, so as to form a second stack, dipping the second stack and the counter-electrode into an electrolyte solution, and applying a voltage or current between the doped InGaN layer and a counter electrode, to porosify the doped InGaN layer, and relaxing the unintentionally doped InGaN layer, transferring the doped InGaN layer and the unintentionally doped InGaN layer to a support of interest, forming an InGaN layer by epitaxy on the unintentionally doped InGaN layer, whereby a relaxed epitaxially grown InGaN layer is obtained.
