1. An organic opto-electronic device comprising:
- a first flip-chip part with a first electrode of thickness D1 formed on a first substrate;
a second flip-chip part with a second electrode formed on a second substrate and carrying an organic stack, the thickness of the second electrode and the organic stack being D2; and
non-conductive spacers of thickness D, with D=k(D1+D2) and 0.5≦
k<
1;
wherein the first flip-chip part and the second flip-chip part are flipped together such that the organic stack is sandwiched between the first electrode and the second electrode, a minimum distance D is kept between the two substrates by the spacers, and a stabilized interface is formed between the first flip-chip part and the second flip-chip part.

Abstract
The present invention pertains to new flip-chip organic opto-electronic structures and methods for making the same. The new organic opto-electronic device includes at least two separate parts. Each part comprises an electrode and at least one of these electrodes carries an organic stack. After completion of these separate parts both are brought together to form the complete opto-electronic device. It is a crucial aspect of the new flip-chip approach that spacers are integrated on one or both sides of the parts and that an interface formation process is employed.
