Title: Method for fabricating phase shift mask
Inventor: JUNG HO YONG
IPC: H01L21/027
Filed: 2006-12-29
Abstract: A method for manufacturing a phase shift mask is provided to prevent the dimension variation of a phase shift pattern by compensating the critical dimension of pattern during a manufacturing process of the phase shift mask. A phase shift layer(202), a shield layer(204), and an anti-reactive layer(206) are formed on a substrate(200). The anti-reactive layer and the shield layer are patterned. The critical dimension(CD) of the patterned shield layer is measured. In case CD of the shield layer is slammer than a design dimension, a material layer is formed at a side of the shield layer to compensate the CD. The phase shift layer is patterned by using the material layer and the shield layer as masks. The phase shift layer is formed with a molybdenum silicon nitride layer(MoSiN). The shield layer is formed with a chrome layer(Cr). When the material layer is formed, a lateral side of the patterned shield layer is oxidized.

IPC: F42B39/20
Filed: 2005-04-08
Abstract: Disclosed is a piece of cartridged ammunition, particularly blank ammunition, comprising a cartridge shell (3) and a projectile (2) that is inserted therein. A propellant chamber that accommodates a propellant charge (5) is provided in the cartridge shell. The propellant charge (5) is ignited by a pyrotechnic ignition device (13) and develops propellants which act upon the bottom (8) of the projectile and propel the same out of the cartridge shell. In order to prevent the pyrotechnic ignition device and thus also the propellant charge (5) from igniting and the cartridge shell and the projectile from being torn apart and being projected in case of high ambient temperatures, particularly during a fire, relief ducts (14) which are filled with a meltable material, especially a meltable metal (15), are provided between the propellant chamber and the exterior of the cartridge shell (3). The meltable material has a lower melting point than the ignition temperature of the ignition device (13) and the propellant charge (5). If the ambient temperature of the cartridge shell rises above the melting temperature of the meltable material, said meltable material melts and unblocks the relief ducts (14) such that the propellant charge burns without pressure building up when the propellant charge is ignited later on while the cartridge shell and the projectile remain interconnected.
