Abstract: A method for fabricating a semiconductor device comprises the step of depositing an insulation film 32a with a first pressure set in a deposition chamber; the step of gradually decreasing the pressure in the deposition chamber to a second pressure which is lower than the first pressure; and the step of further depositing the insulation film 32b with the second pressure set in the deposition chamber. The insulation film is deposited with the first pressure a little lower than a second pressure set in a deposition chamber, and the insulation film is further deposited with the second pressure lower than the first pressure set in the deposition chamber. Furthermore, the insulation film is not deposited in the state where the pressure in the deposition chamber is extremely low, and an atmosphere in the deposition chamber is unstable. Thus, a semiconductor device having the insulation film with a sufficiently flat surface can be fabricating without using reflow process.

Abstract: A covered substrate is described, which comprises: (a) a flexible substrate layer; and (b) a plurality of cooperative barrier layers disposed on the substrate layer. The plurality of cooperative barrier layers further comprise one or more planarizing layers and one or more high-density layers. Moreover, at least one high-density layer is disposed over at least one planarizing layer in a manner such that the at least one high-density layer extends to the substrate layer and cooperates with the substrate layer to completely surround the at least one planarizing layer. When combined with an additional barrier region, such covered substrates are effective for enclosing organic optoelectronic devices, such organic light emitting diodes, organic electrochromic displays, organic photovoltaic devices and organic thin film transistors. Preferred organic optoelectronic devices are organic light emitting diodes.

Abstract: A semiconductor package substrate is provided, which can meet the move toward high integration of semiconductors. A nickel layer is plated on an electroplated copper foil to form a wiring pattern. An LSI chip is mounted on the copper foil, and terminals of the LSI chip and the wiring pattern are connected by wire bonding, followed by sealing with a semiconductor-sealing epoxy resin. Only the copper foil is dissolved away with an alkali etchant to expose nickel. With a nickel stripper having low copper-dissolving power, the nickel layer is removed to expose the wiring pattern. A solder resist is coated, and a pattern is formed in such a way that connecting terminal portions are exposed. Solder balls are placed at the exposed portions of the wiring pattern and are then fused. The wiring pattern is connected to an external printed board via the solder balls.

Abstract: Wafer-level stage testing of semiconductor lasers can be facilitated by directing a light beam emitted from the semiconductor laser toward a direction different from a path of the light beam as originally emitted from the laser. A test structure can be coupled to a back facet of the laser and can include a first region separated from a second region by an inclined interface. When a light beam is emitted from the laser, the light beam can be received on the inclined interface and then directed toward a light detector for detection and evaluation.
