  • Patent number: 7649270
    Abstract: A collective substrate (1) is produced by firing a ceramic green sheet and forming through-holes (11) in the resulting substrate. The through-holes (11) each have an interior surface including taper surfaces (11b, 11c) which are tapered as having an opening size progressively decreasing from a main surface (21) and an external connection surface (22) toward a minimum size hole portion (11a). The taper surfaces (11b, 11c) respectively form obtuse angles ?1, ?2 with the main surface (21) and the external connection surface (22). A semiconductor element mount (BL) includes an insulative member (2) cut out of the collective substrate (1). An imaging device (PE2) includes an imaging element (PE1) mounted in a region surrounded by a frame (4) which is bonded to the main surface (21) of the insulative member (2) and closed by a cover (FL).

  • Publication number: 20090000549
    Abstract: There is provided a substrate processing method and apparatus which can measure and monitor thickness and/or properties of a film formed on a substrate as needed, and quickly correct a deviation in process conditions, and which can therefore stably provide a product of constant quality. A substrate processing method for processing a substrate having a metal and an insulating material exposed on its surface in such a manner that a film thickness of the metal, with an exposed surface of the metal as a reference plane, is selectively or preferentially changed, including measuring a change in the film thickness and/or a film property of the metal during and/or immediately after processing, and monitoring processing and adjusting processing conditions based on results of this measurement.

  • Patent number: 7433777
    Abstract: An engine protection system for a construction machine can individually diagnose the exhaust temperature specific to each cylinder of an engine corresponding to an engine revolution speed in order to find an abnormal condition of each engine cylinder in advance. A revolution speed sensor 14 detects revolution speed of an engine mounted in the construction machine and, a plurality, e.g., 16, cylinder temperature sensors 20a-20p detect exhaust temperatures of respective cylinders of the engine. A data recording unit 26 and a display controller 24 store the detected engine revolution speed and the detected exhaust temperatures of the respective cylinders. Trend data, which is produced based on the stored data, is sent to an office via a portable terminal and the display controller 24 outputs, a signal for playing back and displaying snapshots based on the stored data to a display unit 23 disposed in the cab 5.

  • Publication number: 20080138508
    Abstract: A substrate processing method is useful for forming, by electroless plating, a protective film, such as a magnetic film, which covers exposed surfaces of embedded interconnects composed of an interconnect material, such as copper or silver, embedded in fine interconnect recesses provided in a surface of a substrate. The substrate processing method includes bringing a surface of a substrate into contact with a processing solution whose temperature is adjusted to not more than 15° C., thereby activating the surface, and bringing the activated surface of the substrate into contact with a plating solution, thereby forming a metal film on the surface.
