Abstract
Methods and systems for adhering microfeature workpieces to support members are disclosed. A method in accordance with one embodiment of the invention includes disposing a first adhesive on a surface of a microfeature workpiece, and disposing a second adhesive on a surface of a support member. The method can further include adhesively attaching the microfeature workpiece to the support member by contacting the first adhesive with the second adhesive while the second adhesive is only partially cured. In further particular embodiments, the first and second adhesives can have different compositions, and the second adhesive can be fully cured after the microfeature workpiece and support member are adhesively attached.

50. A microfeature workpiece system, comprising:
-
a microfeature workpiece having a first major surface, a second major surface facing away from the first major surface, and an edge surface between the first and second major surfaces;
a support member positioned adjacent to the microfeature workpiece;
an adhesive assembly disposed between the microfeature workpiece and the support member to couple the microfeature workpiece and the support member, the adhesive assembly including a first layer having a first composition and a first generally uniform thickness, the adhesive assembly including a second layer having a second composition different than the first composition and having a second generally uniform thickness, wherein the adhesive assembly is at least generally out of contact with the edge surface of the microfeature workpiece, and wherein the adhesive assembly is configured to fail at a location between a first interface and a second interface when the assembly is subjected to a stress, the first interface being at a juncture of the adhesive assembly and the support member, the second interface being at a juncture of the adhesive assembly and the microfeature workpiece; and
an electrical coupling connected between the support member and the second major surface of the microfeature workpiece. - View Dependent Claims (51)
