Claim 7:
8. A method, comprising:
forming a package including:
forming a layer of resin on a support, forming the layer of resin includes forming a first protrusion that extends outward from the layer of resin and separates a first surface of the layer of resin from a second surface of the layer of resin;
coupling a plate to the layer of resin by forming a layer of bonding material on the first surface of the layer of resin and depositing the plate on the layer of bonding material and the first protrusion;
forming at least one region of a material on the second surface of the layer of resin, the material having physical properties that change when the package is heated; and
forming an opening extending from an inner cavity of the package to an external environment outside the package along the at least one region of the material by heating the package.
