Granted: 2002-08-01
Abstract: The present invention provides a semiconductor device and semiconductor module. In the prior art of the flexible circuit assembly (FCA) assembled in the hard disk of computer for fixing the read/write amplification IC, but the heat dissipation property of the read/write amplification IC is bad, which results in the temperature rising of the read/write amplification IC, the read/write speed is greatly reduced to affect the characteristics of the hard disk itself. A heat radiation electrode (15) is exposed from the back surface of an insulating resin (13), and a metal plate (23) is affixed to the heat radiation electrode (15). The back surface of this metal plate and the back surface of the flexible sheet are substantially within the same plane, so that it is readily affixed to a second supporting member (24). Accordingly, the heat generated by the semiconductor chip can be efficiently dissipated via the heat radiation electrode (15), the metal plate (23) and the second supporting member (24).

IPC: B01D39/14
Filed: 2001-04-12
Granted: 2002-01-01
Abstract: This invention provides a method for preparing a decomposition catalyst for an organic halide, which comprises reacting a salt of Pt and/or Pd, an alkoxide derivative of Ti and an amino acid of an organic binding compound in a solvent, to synthesize an organic metal precursor containing Ti and Pt and/or Pd within a molecule thereof, and heating the precursor to prepare the decomposition catalyst comprising microparticles of Pt and/or Pd dispersed in TiO2; the above decomposition catalyst can be carried on the surface of the clean side of a ceramic filter. The method allows uniform dispersion of Pt and/or Pd microparticles in TiO2 particles which can increase active sites of the resultant catalyst, leading to a higher activity of the catalyst than that of a conventional catalyst. As a result, the catalyst exhibits excellent decomposition activity even at a temperature lower than 200 DEG C.
