IPC: H01L21/28
Filed: 1985-04-10
Abstract: PURPOSE:To obtain the luminous element of good performance for which the crystal of the sufficiently reduced defect density by low-temperature process can be used by bringing an In-Ga melt in contact with an N-type low resistance ZnSxSe1-x epitaxial layer by the temperature in the vicinity of room temperature while oscillating them. CONSTITUTION:On an N-type low resistance ZnS epitaxial layer 2, a small quantity of a Ga melt 3 including In of 24.5wt% is dropped and a probe 4 having a round end oscillates the dropping part. As a result, the part which sheds the melt firstly becomes wet and is in contact tightly. Ga is a metal whose melting point is 15.6 deg.C and forms a melt including in by heating slightly. The material of ZnSxSe1-x(0<=x<=1) group is poor at wettability and tends to shed the melt as liquid drops. But, it case of the InGa melt, though it sheds firstly, a deposited part on a nuclei is formed on the surface as it is oscillated and gradually the overall surface becomes wet uniformly.
