  • Publication number: 20070090521
    Abstract: It is an object of the present invention to provide a circuit device in which a plurality of circuit elements including a circuit element having a hollow inside are sealed with resin, and to provide a method of manufacturing the same. A circuit device (10) has a first circuit element (13A) having a hollow inside and a plurality of second circuit elements (13B) electrically connected to the first circuit element (13A). The first and second circuit elements (13A) and (13B) are sealed with sealing resin (15). The distances by which the first circuit element (13A) is separated from the second circuit elements (13B) are longer than those by which the second circuit elements (13B) are separated from each other.

  • Patent number: 7075188
    Abstract: In order to provide a circuit device 10 where a second circuit element 15B is exposed from a sealing resin 16, a circuit device 10A comprises: an island 12 to whose top a first circuit element 15A is fixedly fitted; a plurality of leads 11 which are extended around the island 12 and electrically connected to the first circuit element 15A; a sealing resin 16 which seals the first circuit element 15A, the island 12, and leads 11 and forms a cavity portion 18; and a second circuit element 15B stored in the cavity portion 18. Accordingly, since the second circuit element 15B can be externally provided, the degree of freedom for mounting can be improved.

  • Patent number: 5235426
    Abstract: A method of operating a solid state image sensing device having a plurality of electron transfer channels; first and second photodiodes; and first, second, third and fourth electrodes disposed on the electron transfer channels and surrounding the first and second photodiodes. The method includes the step of applying a first potential to the first electrode to transfer electrons from the second photodiode to an electron transfer channel and simultaneously applying a lower potential to the second, third and fourth electrodes to prohibit the electron transfer from the second photodiode to the transfer channel. The method also applies the first potential to the third electrode to transfer electrons from the first photodiode to the electron transfer channel and simultaneously applies the lower potential to the first, second and fourth electrodes to prohibit the electron transfer from the first photodiode to the electron transfer channel.
