Patent ID: 7560640

Claim:
A method, comprising: forming a plurality of bottom electrodes on a substrate; after forming the first plurality of bottom electrodes, forming a first plurality of thermoelectric cooling elements on the plurality of bottom electrodes, the first plurality of thermoelectric cooling elements separated by a plurality of trenches; after forming the first plurality of thermoelectric cooling elements, forming a insulating layer adjacent sides and bottoms of the plurality of trenches and tops of the first plurality of thermoelectric cooling elements; and after forming the insulating layer, forming a second plurality of thermoelectric cooling elements adjacent the insulating layer, each thermoelectric cooling element of the second plurality being formed between two thermoelectric cooling elements of the first plurality of thermoelectric cooling elements; wherein one element of the first plurality of thermoelectric cooling elements and one element of the second plurality of thermoelectric cooling elements are formed on each of the plurality of electrodes.
