Method of producing an optoelectronic component and component
View Patent ↗A method of producing an optoelectronic component including providing an epitaxially grown layer sequence on a growth substrate, which comprises a suitable layer for light emission; applying a metal layer to the epitaxially grown layer sequence; applying a molding support to the metal layer, the molding support including a support material with a first coefficient of thermal expansion and a fiber mesh with a second coefficient of thermal expansion functionally bonded to the support material; and detaching the growth substrate.
1. An arrangement of a plurality of optoelectronic components spaced apart from one another on a tape, the optoelectronic components comprising:
an epitaxially grown layer sequence suitable for light emission in a main direction;
a metal layer on a side of the epitaxially grown layer sequence remote from the main direction; and
a molding support with a support material with a first coefficient of thermal expansion and with a fiber mesh with a second coefficient of thermal expansion functionally bonded to the support material;
wherein part of the fiber mesh and of the support material is arranged in interspaces between two adjacent components.
2. The arrangement according to claim 1 , wherein the second coefficient of thermal expansion in the glass transition temperature range of the support material and above is lower than the first coefficient of thermal expansion.
3. The arrangement according to claim 1 , wherein the fiber mesh is embedded in the support material.
4. The arrangement according to claim 1 , wherein the support material is bonded to the fibers of the planar-extensive mesh by formation of covalent bonds.
5. The arrangement according to claim 1 , wherein a film thickness of the molding support is substantially to 1.5 to 4 times a film thickness of the metal layer.
6. The arrangement according to claim 1 , wherein the support material comprises at least one of epoxy resin and plastics.
7. The arrangement according to claim 1 , wherein the fiber mesh comprises at least one of aramide fibers, glass fibers, Zylon fibers, poly(p-phenylene-2,6-benzobisoxazole), polyhexamethylene adipamide fibers, polycaprolactam fibers, and polyacrylonitrile.
