Optoelectronic device and method for the production thereof

An optoelectronic device comprising:

• an optoelectronic component with a first substrate on which are arranged an active region and a first contact region;
• at least one first contact layer arranged in the first contact region;
• and
• a second component with a second substrate on which is arranged at least one second contact layer arranged in a second contact region,
• wherein
• the first contact layer connects electrically conductively with the active region,
• the first contact layer and the second contact layer are bonded together electrically conductively via an adhesive layer comprising an electrically conductive adhesive, and
• the first contact layer and/or the second contact layer are at least partly patterned.

The method of producing an optoelectronic device comprising:

• A) providing an optoelectronic component with an active region and at least one first contact layer arranged on a first substrate in a first contact region, the first contact layer being connected electrically conductively with the active region;
• B) providing a second component with a second substrate with at least one second contact layer arranged in a second contact region;
• D) applying an electrically conductive adhesive in the first contact region and/or in the second contact region;
• and
• E) arranging the second substrate over the first substrate such that the first contact layer connects electrically conductively with the second contact layer via the electrically conductive adhesive;
• wherein the first contact layer and/or the second contact layer are here applied in a step C1) in patterned manner before being provided or are patterned in a step C2) subsequent to step A) and/or step B).

The optoelectronic device comprising:

• an optoelectronic component with a first substrate on which are arranged an active region and a first contact region,
• at least one first contact layer arranged in the first contact region,
• a second component with a second substrate on which is arranged at least one second contact layer arranged in a second contact region,
• wherein
• 1) the first contact layer connects electrically conductively with the active region,
• 2) the first contact layer and the second contact layer are bonded together electrically conductively via an adhesive layer comprising an electrically conductive adhesive,
• 3) the first contact layer and/or the second contact layer are patterned at least in part, and
• 4) the first contact layer and/or the second contact layer comprises sub-regions separated from one another at least in part by separating regions filled with the electrically conductive adhesive, the sub-regions being connected together electrically conductively.
