Abstract:
1. A method for producing chip devices, the method comprising: providing a wafer having a plurality of chip components; separating the wafer into individual chip components and/or into groups of chip components; applying individual chip components and/or groups of chip components from the wafer to a carrier element, in such a way that interspaces having a predetermined width are formed between the individual chip components and/or the groups of chip components; introducing a first polymer into the interspaces along a first direction and substantially parallel to a major surface of the carrier element; introducing a second polymer different from the first polymer into the interspaces along a second direction that is substantially perpendicular to the first direction and substantially parallel to the major surface of the carrier element, wherein the introducing the first polymer and the introducing the second polymer form a composite element composed of the chip components and a polymer matrix; and separating the composite element, the separating the composite element forming chip devices each comprising at least one of the chip components and at least a portion of the polymer matrix; wherein the first polymer and the second polymer have physical properties that cause the first polymer and second polymer to, after the separating the composite element, at least partially counteract an anisotropic thermal expansion of the chip components in the first and second directions.
