  • Patent number: 6982421
    Abstract: To both increase the efficiency of conversion into EUV radiation energy and also increase the amount of emerging EUV radiation in an EUV source a discharge tube is connected to a gas supply space for supply of the discharge gas which in located radially with respect to an optical axis. The discharge gas is supplied to the discharge space through the gas supply space, passes through the center opening of the anode, emerges from the discharge part and is afterwards evacuated from an evacuation opening. The anode and the cathode are connected to a pulse current source. Discharge plasma is produced and EUV radiation is formed by a heavy current pulse from the pulse current source within the discharge space of the discharge tube. The EUV radiation which has formed passes through a through-opening of the anode and is emitted to the outside.

  • Patent number: 6940072
    Abstract: A radiation detection device includes a light-receiving device array with a plurality of light-receiving devices arranged on a substrate to form a light-receiving portion and a plurality of bonding pads electrically coupled to the light-receiving devices of the light-receiving portion to form a bonding pad portion. A scintillator layer is deposited over at least a portion of the light-receiving devices for converting radiaton into detectable light. A radiation-transmitable, moisture-resistant protective film covers at least the scintillator. A coating resin is located in proximity to a periphery of the moisture-resistant prptective film, with the periphery of the moisture-resistant protective film being fixed to the light-receiving device array with the coating resin.
