Abstract:
A process for producing layers of compound semiconductors on a substrate by means of epitaxy, comprising the steps of:providing a target material comprising a first component of a compound semiconductor material to be deposited epitaxially,providing a gas surrounding the target material, said gas comprising a second component of the compound semiconductor material to be deposited epitaxially,providing a supply of energy to the target material to remove said first component from the target by ablation,using said supply of energy as a sole supply of energy for causing a reaction of said first component removed from the target with said second component in said gas to form said compound semiconductor material,wherein a particle stream emanating from the target and comprising said components of said compound semiconductor material is formed, andproviding a carrier gas stream to convey said components of said compound semiconductor material in said particle stream in a direction of the substrate to enable said compound semiconductor material to grow as an epitaxial layer on the substrate.
