摘要:
The present invention relates to a tree resistant, cross-linkable polyolefin resin composition for insulation capable of improving electric properties of an insulator of the high voltage power cable and thus improving a long-life stability of an underground distribution cable as having a more superior resistance to water tree deterioration caused by moisture, superior thermal-oxidative stability, superior scorch resistance when extruding as well as obtaining a proper cross-linking degree when cross-linking.
摘要:
A composition for cleaning a phase shift mask, including an organic acid ammonium salt, wherein a base ionization constant (Kb) of organic acid ions is larger than an acid ionization constant (Ka) of ammonium ions, hydrogen peroxide, and water, and associated methods.
摘要:
A photomask includes an ion trapping layer and a method of manufacturing a semiconductor device uses the photomask. The photomask includes a transparent substrate and an ion trapping layer formed on a first region of the transparent substrate to trap ions present near the transparent substrate. In manufacturing a semiconductor device, a photosensitive film formed on a substrate is exposed through the photomask in which the ion trapping layer is formed on the transparent substrate, and the substrate is processed using the photosensitive film obtained as the result of the exposure.
