The third sealing resin seals the other side of the conductor and has a linear thermal expansion coefficient and thickness which may restrain at least a part of flexion of the conductor caused by the linear thermal expansion of the second sealing resin. The first sealing resin seals at least a part of the conductor, is sandwiched between the second sealing resin and the third sealing resin, and has a linear thermal expansion coefficient which may restrain at least a part of the linear thermal expansion of the second sealing resin.Type: ApplicationFiled: May 30, 2008Publication date: December 4, 2008Applicant: NEC ELECTRONICS CORPORATIONInventor: Taibo NAKAZAWA

Publication number: 20080296751Abstract: A semiconductor package is revealed, primarily comprising a substrate, a chip disposed on the substrate, and an encapsulant to encapsulate the chip. The substrate has a plurality of dimples formed in its top surface thereof without penetrating through the substrate and located at a non-wiring region outside a chip mounting region. Therefore, without changing the appearance of the semiconductor package, the diffusion path of moisture and the adhesive strength between the encapsulant and the substrate can be increased to achieve functions of anti-humidity and anti-delamination.Type: ApplicationFiled: May 29, 2007Publication date: December 4, 2008Inventor: Wen-Jeng Fan

Publication number: 20080296753Abstract: The surface mount package is assembled from a ceramic base which is imprinted on its upper and lower surfaces with conductive patterns for attachment of and connection to an electronic or electromechanical device, a molded dielectric layer for forming a cavity and a seal ring. The molded dielectric is formed by aligning a dielectric preform with the base, positioning the seal ring on top of the preform, then applying a mold over the layers to shape the dielectric during a firing process that fuses the base, preform and seal ring to create a hermetic seal. The preform is of sufficient thickness that the electronic device will be fully contained within the cavity when placed into the completed package.Type: ApplicationFiled: May 31, 2007Publication date: December 4, 2008Inventor: JERRY L.

Publication number: 20080296754Abstract: A method and apparatus to minimize thermal impedance using copper on the die or chip backside. Some embodiments use deposited copper having a thickness chosen to complement a given chip thickness, in order to reduce or minimize wafer warpage. In some embodiments, the wafer, having a plurality of chips (e.g., silicon), is thinned (e.g., by chemical-mechanical polishing) before deposition of the copper layer, to reduce the thermal resistance of the chip. Some embodiments further deposit copper in a pattern of bumps, raised areas, or pads, e.g., in a checkerboard pattern, to thicken and add copper while reducing or minimizing wafer warpage and chip stress.Type: ApplicationFiled: July 24, 2008Publication date: December 4, 2008Inventors: Fay Hua, Gregory M. Chrysler, James G. Maveety, K. V. Ravi
