Title: Semiconductor device and manufacture thereof
Inventor: TAKAHASHI KENJI
IPC: H01L23/31
Filed: 1986-01-31
Abstract: PURPOSE:To prevent a passivation film from cracks, to reducd the number of soft errors, and to improve moisture-resistant features in a large semiconductor chip by a method wherein a thick protecting film is formed on the upper surface of the semiconductor chip. CONSTITUTION:A thick second protecting film 5 laid on the upper surface of a semiconductor chip reduces the stress, which may be present on a semiconductor chip, attributable to the difference in thermal expansion factor between a molding resin and the semiconductor chip. This effectively reduced stress- caused semiconductor chip pattern deformation, cracks in a protecting film 3 that is for example a passivation film, and deformation of bonding wires, all contributing to the realization of stable characteristics. With the thick second protecting film 5 stopping alpha-rays, there will be a decrease in the number of soft errors in a memory element. Further, a bonding pad 2 is provided with protecting films 4, 5, which ensures a reliable wire bonding for an excellent electrical connection.

IPC: G02B6/02
Filed: 1998-01-30
Abstract: PROBLEM TO BE SOLVED: To provide a dispersion shift fiber(DSF) which is suitable for light- wavelength division multiplex transmission. SOLUTION: A refractive index distribution and a core diameter ratio are found so as to obtain an optimum mode filed diameter and an optimum dispersion gradient. In concrete, nonlinearlity and a low dispersion gradient are both obtained by setting the specific refractive index difference (Δ1 ) to the refractive index of pure silica of a center core 1 to +0.7 to +0.85%, a refractive index distribution parameter (α constant) to 1.2 to 1.8, the specific refractive index difference of a 1st side core 2 to -0.05 to +0.1%, the specific refractive index difference (Δ3 ) to +0.3 to +0.6%, the radius (a1 /2) of the 1st side core 2 to 2 to 4.5 μm, and the radius (a2 /2) of the 1st side core 2 to 7 to 12.5 μm and the radius (a3 /2) of the 2nd core 3 to 7-12.5 μm.  Judging from that the nonlinearlity can be obtained, waveform distortion of signal light can be controlled for fast, large-capacity transmission and judging from the small dispersion gradient, a wide wavelength range can be used for the signal light.

Abstract: PROBLEM TO BE SOLVED: To prevent a conductive polymer compound layer from peeling off and provide a reliable solid electrolyte capacitor with solid electrolyte made of a conductive polymer compound. SOLUTION: A conductive molecular compound layer is formed in a tantalum porous pellet 1 through a chemical polymerization step.
