摘要： A method of producing an oxide glass thin film includes a process to obtain a transparent glass film, in which volatilization of additives in a porous film deposited is effectively suppressed and which can provide an oxide glass thin film having a desired arrangement of refractive index with a low optical loss. The method is for producing an oxide glass thin film, in which glass fine particles mainly containing SiO.sub.2 with additives are deposited on a substrate to form a porous thin film and then heated to form a transparent glass film. In the method, vapor of oxides of additive components is mixed in an atmosphere in which the porous thin film is heated to form the transparent glass film, whereby stopping the volatilization of the additives in the porous film deposited, preventing diffusion of the additives added to a core layer, and preventing the volatilization of glass transition temperature lowering components of additives (P.sub.2 O.sub.5, B.sub.2 O.sub.3, GeO.sub.2, etc.). By these, a desired arrangement of refractive index may be obtained, and an oxide glass thin film may be obtained while lowering the optical loss such as the optical scattering, which could be caused by bubbles in an unsintered portion.

摘要： Polyester sheets are produced by melting a low-viscosity polyester such as a recovered polyester under reduced pressure, extruding the melt into a sheet, and stretching the sheet in the direction of width by 2.5 to 120%. The polyester resin of the oriented sheet thus obtained has an intrinsic viscosity of 0.40 to 0.63. Polyester sheets can be produced readily and continuously from recovered polyester resins or polyester resins below standards, which have a low intrinsic viscosity, and the cost of production of polyester sheets is reduced. These sheets can be formed into various shaped articles by vacuum forming, pressure forming or the like without occurrence of draw-down and without giving defective shaped articles.

摘要： According to a lead-free solder bump bonding structure, by causing the interface (IMC interface) of the intermetallic compound layer at a lead-free-solder-bump side to have scallop shapes of equal to or less than 0.02 [portions/μm] without forming in advance an Ni layer as a barrier layer on the surfaces of respective Cu electrodes of first and second electronic components like conventional technologies, a Cu diffusion can be inhibited, thereby inhibiting an occurrence of an electromigration. Hence, the burden at the time of manufacturing can be reduced by what corresponds to an omission of the formation process of the Ni layer as a barrier layer on the Cu electrode surfaces, and thus a lead-free solder bump bonding structure can be provided which reduces a burden at the time of manufacturing in comparison with conventional technologies and which can inhibit an occurrence of an electromigration.
摘要翻译：根据无铅焊料接合结构，通过使无铅焊料凸点侧的金属间化合物层的界面（IMC界面）具有等于或小于0.02 [份/μm]的扇形，在不像传统技术那样在第一和第二电子部件的各个Cu电极的表面上预先形成Ni层作为阻挡层的情况下，可以抑制Cu扩散，从而抑制电迁移的发生。因此，可以通过对作为Cu电极表面上的阻挡层的Ni层的形成处理的省略来减少制造时的负担，从而可以提供无铅焊料凸块接合结构，其中，与传统技术相比，减少制造时的负担，并且可以抑制电迁移的发生。
