- 2. The method of claim 1, wherein the thin film adhesive material comprises an adhesive material selected from the group consisting of epoxies, cynates esters, cynate ester/epoxy blends, and silicones.
- 3. The method of claim 1, wherein the thin film adhesive material has a substantially uniform thickness of from about 0.0005 to about 0.006 inch.
- 4. The method of claim 1, wherein the predetermined locations comprise surfaces of chip pockets of an ink jet pen.
- 5. The method of claim 1, wherein the step of engaging the second adhesive surface of the cut portions with predetermined locations on a receiving surface comprises providing one or more engagement members and urging a surface of each engagement member having an affinity for the cut portions against the first adhesive surface of each of the cut portions.
- 6. A method for attaching a plurality of a semiconductor chips to an ink jet pen body which comprises the steps of(a) providing a sheet of a thin film adhesive material having a first adhesive surface opposite a second adhesive surface and a carrier web releasably attached to the second adhesive surface using a low tack adhesive, (b) providing a unitary cutting/application device with a movable engagement member having an adhesive affinity for the first adhesive surface, and pressing the unitary cutting/anplication device against the first adhesive surface to simultaneously make a plurality of cuts in the sheet of thin film adhesive material and to adhere the first adhesive surface to the engagement member, the cuts extending from the first adhesive surface to an interface between the second adhesive surface and the carrier web without significantly extending into the release carrier web to provide one or more cut portions of adhesive film; (c) simultaneously removing the cutting/application device from the sheet of thin film adhesive material wherein each cut portion of adhesive film is removed from the carrier web and remains adhesively attached to the engagement member of the cutting/application device; (d) simultaneously engaging the second adhesive surface of each of the cut portions with predetermined locations on the ink jet pen body having an adhesive affinity for the second adhesive surface that is greater than the adhesive affinity of the engagement member for the first adhesive surface using the cutting/application device by urging the engagement member to press the second adhesive surface of the cut portions against the predetermined locations and thereafter withdrawing the engagement member away from the predetermined locations such that the second adhesive surface of the cut portions remains adhesively secured to the predetermined locations while the first adhesive surface of the cut portions separates from the engagement member; and (e) providing a plurality of semiconductor chips in a desirably aligned configuration with respect to the predetermined locations and substantially simultaneously contacting each semiconductor chip with the first adhesive surface of each of the cut portions to adhesively secure the semiconductor chips to the first adhesive surface of the cut portions.
- 7. The method of claim 6 wherein the cut portions comprise an adhesive film selected from the group consisting of epoxies, cynates esters, cynate ester/epoxy blends, and silicones.
- 8. The method of claim 6 wherein the cut portions have a substantially uniform thickness of from about 0.0005 to about 0.006 inch.
- 9. The method of claim 6 wherein the carrier web comprises a low-tack adhesive layer for releasably engaging the cut portions of the film material thereto.
- 10. The method of claim 6 further comprising curing the cut portions in order to adhesively bond the chips to the ink jet pen body.
- 11. A method for attaching one or more components of a microelectronic device to a portion of the microelectronic device during construction thereof, the method comprising the steps of(a) providing a sheet of a thin film adhesive material having a first adhesive surface opposite a second adhesive surface and a carrier web releasably attached adjacent the second adhesive surface, (b) providing a unitary cutting/application device with a movable engagement member having an adhesive affinity for the first adhesive surface, and pressing the unitary cutting/application device aaainst the first adhesive surface to make a plurality of cuts in the sheet of thin film adhesive material and to adhere the first adhesive surface to the engagement member, the cuts extending from the first adhesive surface to an interface between the second adhesive surface and the carrier web without significantly extending into the carrier web to provide one or more cut portions of adhesive film; (c) removing the cutting/application device from the sheet of thin film adhesive material wherein each cut portion of film is removed from the carrier web and remains adhesively attached to the engagement member of the cutting/application device; (d) engaging the second adhesive surface of each of the cut portions with predetermined locations on the microelectronic device having an adhesive affinity for the second adhesive surface that is greater than the adhesive affinity of the engagement member for the first adhesive surface using the cutting/application device by urging the engagement member to press the second adhesive surface of the cut portions against the predetermined locations and thereafter withdrawing the engagement member away from the predetermined locations such that the second adhesive surface of the cut portions remains adhesively secured to the predetermined locations while the first adhesive surface separates from the engagement member; (e) contacting one or more microelectronic components with the first adhesive surface of the cut portions to adhesively secure the microelectronic components to the first adhesive surface of the cut portions; and (f) curing the cut portions in order to bond the one or more components to the microelectronic device.
- 12. The method of claim 11, wherein the thin film adhesive material comprises an adhesive material selected from the group consisting of epoxies, cynates esters and cynate ester/epoxy blends and silicones.
- 13. The method of claim 11, wherein the thin film adhesive has a substantially uniform thickness of from about 0.0005 to about 0.006 inch.
