  • Publication number: 20160194517
    Abstract: An underfill material achieving a wide margin for mounting and a method for manufacturing a semiconductor device using the same are provided. The underfill material contains an epoxy resin, an acid anhydride, an acrylic resin, and an organic peroxide, wherein a minimum melt viscosity attainment temperature and a minimum melt viscosity obtained when melt viscosity of the underfill material is measured under a temperature increase rate condition in a range of 5 to 50° C./min are in a range of 100° C. to 150° C. and in a range of 100 to 5000 Pa·s, respectively. Since variation in the minimum melt viscosity attainment temperature measured under different temperature increase conditions is small, voidless mounting and good solder bonding properties can be achieved without strict control on the temperature profile during thermocompression bonding, and a wide margin for mounting can be achieved.

Another object is to provide a transparent conductive film that is formed using conductive oxynitride including zinc and aluminum. When aluminum and nitrogen are made to be included in a transparent conductive film formed using oxide including zinc to form a transparent conductive film that is formed using conductive oxynitride including zinc and aluminum, the transparent conductive film can have reduced resistivity. Heat treatment after the formation of the transparent conductive film that is formed using conductive oxynitride including zinc and aluminum enables reduction in resistivity of the transparent conductive film.

  • Patent number: 9269823
    Abstract: In a miniaturized transistor, a gate insulating layer is required to reduce its thickness; however, in the case where the gate insulating layer is a single layer of a silicon oxide film, a physical limit on thinning of the gate insulating layer might occur due to an increase in tunneling current, i.e. gate leakage current. With the use of a high-k film whose relative permittivity is higher than or equal to 10 is used for the gate insulating layer, gate leakage current of the miniaturized transistor is reduced. With the use of the high-k film as a first insulating layer whose relative permittivity is higher than that of a second insulating layer in contact with an oxide semiconductor layer, the thickness of the gate insulating layer can be thinner than a thickness of a gate insulating layer considered in terms of a silicon oxide film.
