摘要:
Methods and apparatus are provided for an electronic panel assembly (EPA) (82, 83), comprising: providing one or more electronic devices (30) with primary faces (31) having electrical contacts (36), opposed rear faces (33) and edges (32) therebetween. The devices (30) are mounted primary faces (31) down on a temporary support (60) in openings (44) in a warp control sheet (WCS) (40) attached to the support (60). Plastic encapsulation (50) is formed at least between lateral edges (32, 43) of the devices (30) and WCS openings (44). Undesirable panel warping (76) during encapsulation is mitigated by choosing the WCS coefficient of thermal expansion (CTE) to be less than the encapsulation CTE. After encapsulation cure, the EPA (82) containing the devices (30) and the WCS (40) is separated from the temporary support (60) and, optionally, mounted on another carrier (70) with electrical contacts (36) exposed. Thin film insulators (85) and conductors (87) are desirably applied to couple electrical contacts (36) on various devices (30) to each other and to external terminals (88), thereby forming an integrated multi-device EPA (84).

Methods and system for forming a microelectronic assembly (82) are provided. A device substrate (50) having a plurality of electronic components (42) coupled thereto is provided. A carrier substrate (54) having first and second opposing surfaces (60, 62) and including a plurality of openings (58) extending between the first and second opposing surfaces (60, 62) and a plurality of depressions (64) formed on the first opposing surface (60) is provided. The device substrate (50) is attached to the first opposing surface (60) of the carrier substrate (54) using an adhesive material (56) such that at least some of the adhesive material (56) is adjacent to at least some of the plurality of depressions (64).

摘要:
Integrated circuit packages are formed from a panel where the panel is separated by laser cutting the panel. In some embodiments, the panel is attached to the carrier for the formation of interconnect layers on the panel. Afterwards, the panel is cut with a laser while on the carrier to separate the integrated circuit packages. A tape or other type of structure may be attached to the top of the packages after the laser cutting. The integrated circuit packages are removed from the carrier by releasing the adhesive and removing the integrated circuit packages with the tape. The packages are then removed from the tape.
