Abstract:
A method for making an organic opto-electronic device comprising a first flip-chip part with a first substrate and a first electrode and a second flip-chip part with a second substrate and a second electrode which carries an organic stack, the method comprising the steps:forming the first electrode on the first substrate, forming the second electrode on the second substrate, forming the organic stack on the second electrode, forming spacers of thickness D, with D=k(D1+D2) and 0.5&lE;k<1, flipping the first substrate and the second substrate together such that the organic stack is sandwiched between the first electrode and the second electrode, and such that a minimum distance D is kept between the two substrates by the spacers, and applying an interface formation process to form a stabilized interface between the first flip-chip part and the second flip-chip part.
