Title: Sealing structure of semiconductor element
Inventor: NARITA RYOICHI
IPC: C08L83/07
Filed: 1986-09-16
Abstract: PURPOSE:To prevent damage of a semiconductor element and a bump electrode part, by using stable silicone gel characterized by low complex elastic modulus and little change in physical properties, and sealing a semiconductor element, on which the bump electrode is formed. CONSTITUTION:A hybrid IC is constituted by a flip chip IC 1, on which a solder bump 3 is formed, a thick film circuit substrate 1, a sealing material 4 and the like. Owing to the thermal stress of the hybrid IC, there are shearing strain deltaS due to the difference in thermal expansion coefficients between the IC 1 and the substrate 2 and tensile strain deltaE, by which the IC 1 is pushed up due to the thermal expansion of the material 4 that has entered in a gap 9. When the value of the strain deltaE is made smaller than the value deltaS, a thermal fatigue life is improved. The pushing-up force F is obtained as functions of the Young's modulus of the material (silicone gel) 4, the complex elastic modulus G with respect to viscosity and the size of the chip. When the upper limit of the modulus G obtained from the chip size is 5,000dyn/cm<2>, the silicone gel 4, in which the ratio between ethylene and ethane is within 20%, is used.

Filed: 1992-08-17
Abstract: PURPOSE:To obtain a superconducting magnet apparatus wherein eddy current loss in an inner vessel is remarkably reduced and changing magnetic field acting on a superconducting coil is also reduced, by forming a discontinuous conductive metal coating layer on the inner vessel surface. CONSTITUTION:When a copper-plated layer 10 is formed on the surface of an inner vessel 4, boundary lines 11 are formed in which stainless steel as the matrix of the inner vessel is peeled in the form that the copper-plated layer 10 is partially eliminated. Thereby the current path in the peripheral direction of the superconducting coil 3 is divided. A part where a large eddy current flows through a copper-plated layer 11 on the inner vessel 4 surface when changing magnetic field is applied to a superconducting coil 3 contained in an inner vessel 4 together with refrigerant is thickly formed, and a part where a small eddy current flows is thinly formed. Hence Joule heat loss due to the eddy current induced in the inner vessel container by the changing magnetic field is reduced, and the heat generation at the time of excitation can restrained to be low, so that the reliability of a superconducting magnet apparatus can be improved.
