Verfahren zum Herstellen eines kontaminationsgeschützten, optoelektronischen Bauelements und kontaminationsgeschütztes, optoelektronisches Bauelement

摘要

The opto-electronic component, to transmit and/or receive electromagnetic rays, is especially a semiconductor chip with at least a partial shrouding mass (3) of a material permeable to electromagnetic rays. After shrouding, the material surface is treated chemically or by a plasma to form surface groups of Si-O or Si-OH to prevent the adhesion of impurities. - The surface can be treated with an organic or inorganic acid e.g. sulfuric acid, nitric acid or tartaric acid. The plastics housing body (1) has a recess (10) to take a LED chip (2) with electrical connections (4). The shrouding mass molding has molecules (5) of n-butyltrimethoxysilane and/or diphenyldimethoxysilane.
