Title:
LIGHT EMITTING ELEMENT AND ITS MANUFACTURE
Document Type and Number:
Japanese Patent JPH0690018
Kind Code:
A
Abstract:
PURPOSE: To provide a light emitting element of porous silicon layer with improved emission efficiency, relating to the light emitting element where a porous silicon layer is formed on a silicon substrate.
CONSTITUTION: A porous silicon layer 4 is formed on the surface of a p-type silicon substrate 2. An insulating film 6, an oxide film of 2nm thickness, is formed on the porous silicon layer 4. A translucent electrode 8 where an Al is deposited to the thickness of 9nm is formed on the insulating film 6. An Al electrode 10 is formed at the bottom of the silicon substrate 2.
