摘要： PROBLEM TO BE SOLVED: To provide a method of producing an electromagnetic wave shield casing where infiltration of water from external environment is prevented surely.
SOLUTION: In a first molding process, the back surface of an insertion material 4 is supported by a surface 108 formed by a metallic mold 10B. Thus, when resin for first molding is poured into the recess 100 of a metallic mold 10A, the insertion material 4 is never deformed. By first molding, an outer wall 6 having a projecting part 6a projecting on the side of an inner wall and a cavity 6b opposing a through hole 41a is formed. In a second molding process, when resin for second molding is poured into the recess 104 of a metallic mold 11B, the resin flows into the cavity 6b from the through hole 41a. Since the insertion material 4 is supported by the outer wall 6 in the case of second molding, the insertion material 4 is never deformed due to pouring of the resin.

摘要翻译：要解决的问题：提供一种防止来自外部环境的水渗入的电磁波屏蔽壳体的制造方法。解决方案：在第一模塑工艺中，插入材料4的背面由金属模具10B形成的表面108支撑。因此，当用于第一次成型的树脂注入到金属模具10A的凹部100中时，插入材料4不会变形。通过第一成型，形成具有在内壁侧突出的突出部6a和与通孔41a相对的空腔6b的外壁6。在第二成型工序中，当第二成型用树脂注入到金属模具11B的凹部104中时，树脂从通孔41a流入空腔6b。由于插入材料4在第二次成形的情况下被外壁6支撑，所以插入材料4由于树脂的浇注而不会变形。版权所有（C）2005，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a semiconductor device having three or more semiconductor chips in parallel wherein a difference in temperatures of the semiconductor chips is made small. SOLUTION: The semiconductor device is provided with five IGBT chips that are arranged in parallel. The IGBT chips 12B-12D arranged inside the parallel arrangement are made smaller in area than the IGBT chips 12A and 12E arranged on both ends of the parallel arrangement. As a result, when compared with a case when the IGBT chips 12A-12E are equal in area to each other, a current flowing in the IGBT chips 12B-12D arranged inside becomes smaller, and a difference in temperatures of the IGBT chips 12A-12E is made small, and a temperature increase of the IGBT rising up to the highest temperature is reduced than heretofore.

摘要： PROBLEM TO BE SOLVED: To provide a semiconductor device where performance of a semiconductor element can sufficiently be derived.
SOLUTION: A sensor diode 302 is arranged in an almost center of a region which is press-fitted by a press fitting heat spreader 304 so that a periphery is surrounded by an IGBT cell 1001. A groove 305 is disposed on the lower face side of the press-fitting heat spreader 304 which is brought into contact with an emitter electrode 1007 of IGBT 101, so that the press-fitting heat spreader 304 does not depress the sensor diode 302 and a temperature sensor harness 303. Thus, responsiveness of a temperature detected by the sensor diode 302 can be improved with respect to a temperature change of IGBT 101 by heat generation of an active region 301. Thus, unnecessary margin is not required as in a conventional semiconductor device at the time of protecting a temperature rise of IGBT 101 based on the temperature detected by the sensor diode 302, and performance of IGBT 101 can sufficiently be derived.
