Title:
LIGHT-EMITTING ELEMENT AND ENERGETIC PARTICLE RADIATION METHOD AND POLISHING METHOD FOR LIGHT-EMITTING ELEMENT
Document Type and Number:
WIPO Patent Application WO/2019/233174
Kind Code:
A1
Abstract:
A polishing method for a light-emitting element. An energetic particle is used to subject a light-emitting element to radiation with an increasing energy gradient, such that damage is homogeneously inflicted on a phase A of the light-emitting element at a predetermined depth range below a surface of the light-emitting element until the Mohs hardness of the phase A is approximately the same as the Mohs hardness of a phase Y. The radiated light-emitting element is then polished to the predetermined depth so as to smooth out the surface thereof.
