METHOD FOR PRODUCING GROUP-III NITRIDE SUBSTRATE

摘要

This method for producing a group-III nitride substrate has: a step of preparing a plurality of seed crystal substrates that are formed in a shape whereby said substrates are lined up and the side surfaces face each other; a step of adhering the seed crystal substrates to a base material using an adhesive such that the substrates are lined up and the side surfaces face each other; a step of growing group-III nitride crystals above the main surfaces of the seed crystal substrates such that the crystals which have grown above the main surfaces bond with each other and become unified; and a step of obtaining a group-III nitride substrate formed by the group-III nitride crystals.
