Abstract:
An optoelectronic thin-film chip is specified, comprising at least one radiation-emitting region (8) in an active zone (7) of a thin-film layer (2) and a lens (10, 12) disposed downstream of the radiation-emitting region (8). The lens is formed by at least one partial region of the thin-film layer (2), the lateral extent (Φ) of the lens (10, 12) being greater than the lateral extent of the radiation-emitting region (δ). A method for producing such an optoelectronic thin-film chip is furthermore specified.
