A multi-unit cosmetic applicator comprising: a housing body, a first cosmetic unit housed in the housing body, a second cosmetic unit housed in the housing body, an opening in the housing, wherein each cosmetic unit has a means for being independently movable relative to each other from a stored position to an advanced position and back to its stored position. For the generation of a predetermined positive etching profile, the side walls of the structures are furnished with the defined slope angle \u03b2 of from 60 degrees to 88 degrees relative to the etching bottom and the structures are generated with an etching depth At in the micrometer region. The leadframe may include a plurality of elongated electrical leads, extending from a first side of the leadframe, beneath the die, and terminating at a second side of the leadframe adjacent to the bond pads along the single edge of the die.
