CA 2617881

The invention relates to a method for preparing an electric circuit comprising a plurality of Light-Emitting Diodes (LEDs) . First, a continuous layer of a first type semiconductor material is provided. On this a first pattern of a material of a second type semiconductor is applied. Next, a substrate comprising a second pattern of at least one conducting layer (34) is attached to the first pattern. After this, the continuous layer is cut according to a third pattern. Thus the plurality of LEDs is formed.

L'invention concerne un procédé pour préparer un circuit électrique comprenant une pluralité de diodes lumineuses (LED). On forme d'abord une couche continue d'un premier matériau semi-conducteur. Sur cette couche on applique un premier motif d'un deuxième matériau semi-conducteur. Ensuite, un substrat comprenant un deuxième motif d'au moins une couche conductrice (34) est attaché au premier motif, après quoi la couche continue est découpée selon un troisième motif. De cette manière, on forme la pluralité de diodes lumineuses (LED).
