摘要:
The present invention provides a method for fabricating a semiconductor device which initially performs chemical mechanical polishing with respect to a metal film made of copper formed on a semiconductor substrate to form wires composed of the metal film on the semiconductor substrate and subsequently removes a wire-to-wire bridge occurring during the formation of the wires and remaining on the semiconductor substrate to cause unneeded conduction between the wires adjacent to each other. The removal of the wire-to-wire bridge is performed by oxidizing the wire-to-wire bridge into a copper oxide by using an aqueous hydrogen peroxide and then dissolving the copper oxide by using an oxalic acid. This allows the removal of the wire-to-wire bridge without damaging the main bodies of the wires.

摘要:
A communication terminal device and a method for controlling the same which can operate a mail restriction function effectively without increasing a mail address registered for the mail restriction function are provided. The transmission and the reception of the mail is restricted by storing by a domain conversion table a corresponding relationship between an original domain by the automatic address conversion unit and the domain after the conversion, acquiring by the original domain acquiring unit the original domain based on the domain of the mail address converted by the automatic address conversion unit by referring to the domain conversion table, and controlling by the mail transmission and reception control means the transmission and the reception of the mail by comparing the mail address replaced with the domain of the mail address of the transmitting/receiving mail by the original domain acquired by the original domain acquiring unit with the registered mail address.
摘要:
A resin molded type semiconductor device has an inner portion sandwiched between two outer surfaces. The device includes a chip support with a first, inwardly facing surface and a second, outwardly facing surface. The device also includes a semiconductor element with a first, inwardly facing surface and a second, outwardly facing surface. The respective first surfaces of the chip support and semiconductor element are fixed to each other. A mold resin is provided to seal the entire semiconductor device except for the respective second surfaces of the chip support and semiconductor element which remain exposed as part of the two outer surfaces of the device, in order to keep the semiconductor device thin.
