Abstract:
A method for bonding electronic components finished with electroless NiXP layer for preventing a brittle solder joint fracture is provided with the steps comprising: forming an electroless NiXP metal layer on a metal deposition of electronic components, wherein X is selected from the group consisting of W, Mo, Co, Ti, Zr, Zn, V, Cr, Fe, Nb, Re, Mn, Tl and Cu; and reflowing a lead-free solder on the electroless NiXP layer to be bonded. X element was suppressed the formation of Ni3P, Ni3SnP intermetallic compound and prevented the spalling behavior of Ni3Sn4. Therefore, solder joint reliability can be improved significantly.

PROBLEM TO BE SOLVED: To provide a biochemical substance detection method using surface enhanced Raman scattering for detecting presence or content of a biochemical substance contained in an analysis object. SOLUTION: A surface enhanced Raman scattering spectrum is obtained from many hot spots produced by coupling the analysis object to many noble metal nanoparticles separated physically on a noble metal nanowire surface of a single crystal object. A biochemical substance having high sensitivity, high reproducibility, high reliability, and high precision, and allowing multiplex detection is detected. COPYRIGHT: (C)2011,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a photovoltaic device that reduces an invalid region not functioning as photovoltaic power and increases a valid region. SOLUTION: The photovoltaic device includes a substrate 100 having trenches 101 formed thereon. A first electrode layer 110 and an auxiliary electrode layer having an electric resistance smaller than the first electrode layer 110 are formed in a region between the trenches. A photovoltaic conversion layer is formed on the first electrode layer or the auxiliary electrode layer. A second electrode layer is formed by obliquely depositing second conductive material on the photovoltaic conversion layer. The photovoltaic conversion layer formed inside the trenches is etched to expose the first electrode layer or auxiliary electrode layer. A conductive layer is formed by obliquely depositing third conductive material on the second electrode layer so that the first electrode layer or auxiliary electrode layer formed on one region, out of the regions, in which electricity is generated by light, and the second electrode layer formed in other one region, in which the electricity is generated by light, are electrically connected inside the trenches.

Abstract:
PROBLEM TO BE SOLVED: To provide a transparent siloxane resin composition for optical use applicable to various optical applications by thermal cure of (1) a vinyl-oligosiloxane hybrid, and (2) an organic hydrogen silicone compound including 2 or more silicon-bound hydrogens, (3) through a hydrogen silicidation reaction in the presence of a metal catalyst. SOLUTION: The inorganic network-structure vinyl-oligosiloxane hybrid with high condensation rate is produced by a non-hydrolytic condensation reaction of an organic alkoxysilane having an organic silane diol and vinyl group. The transparent siloxane resin for optical use having high condensation rate and high refractive index can be produced using a mixture in which a part of an organic alkoxysilnae containing a vinyl group is replaced by a metal alkoxide.
