  • Patent number: 6774314
    Abstract: An electronic device assembled using a coupler which has an electroconductive region and a resin region on the surface. Flexibility of the resin region absorbs stress caused by difference in thermal expansion coefficient between an organic printed circuit board and a semiconductor chip through the deformation of the electroconductive region. As a result, formation of cracking in the coupler is avoided. It is preferable that the resin region occupies from 20 to 80% of the total surface area of the coupler. The coupler may be formed from a molten blend of the heat resistant resin and a joining metal. The coupler may also be formed by molding a blend of the heat resistant resin and metal powder, wherein the metal powder locating on the surface of the coupler have a joining metal joined thereto.

  • Publication number: 20040018646
    Abstract: A resist pattern formation method is characterized in that, after a resist pattern is formed on a wafer, a residue generated between resist sidewalls forming the resist pattern is irradiated with an electron beam under a reduced pressure. It is also preferable to detect the residue with pattern defect inspection equipment, and irradiate the detected residue site with an electron beam under a reduced pressure using an electron microscope. The reduced pressure is preferably equal to or lower than 5.0×102 Pa, and an acceleration voltage is preferably equal to or lower than 1200 V. A manufacturing method of a semiconductor device according to the present invention uses the above-described formation method to form a resist pattern. Thus, the residue generated between resist sidewalls can be removed without varying a dimension of a resist pattern spacing.

  • Patent number: 6579657
    Abstract: A resist pattern, containing a material capable of generating an acid by exposure to light, is covered with a resist containing a material capable of crosslinkage in the presence of an acid. The acid is generated in the resist pattern by application of heat or by exposure to light, and a crosslinked layer is formed at the interface as a cover layer for the resist pattern, thereby causing the resist pattern to be thickened. Thus, the hole diameter of the resist pattern can be reduced, or the isolation width of a resist pattern can be reduced.
