  • Patent number: 7022588
    Abstract: The invention relates to a method of manufacturing an electronic component (1), in particular a semiconductor component (1), which is provided with electric connection regions (2), wherein a mark (M), such as a type number, is provided on a surface thereof by means of laser radiation (3). In a method according to the invention, the component (1) is attached with one (4) of its sides (4, 7) to a foil (5) by means of an adhesive layer (6), and the component is provided, on said side (4), with the mark (M) through the foil (5) and the adhesive layer (6). In this manner, a large number of components (1) can be readily provided with a mark (M) without undue handling, and the marking operation can be readily integrated in the complete manufacturing process of the components. Surprisingly it has been found that marking through a radiation-absorbing double layer (5, 6) is very well feasible.
