Disclosed is a thermal treatment apparatus radiating low and high temperature, which includes a low-temperature radiating section and a high-temperature radiating section, and can rotatably scan affected parts. Both the low and the high temperature radiating sections are rotatable. The thermal treatment apparatus according to the present invention further includes a controller, with which a user can adjust the period of time for radiating low and high temperature as well as for rotation of the low-temperature radiating section and the high-temperature radiating section. The low-temperature radiating section is connected to a cryo-pump, while the high-temperature radiating section comprises an infrared ray lamp or a far infrared ray lamp. The present invention is applicable to medical treatment, physical therapy, sterilization of cosmetics or pharmaceuticals, or to tests of critical temperature for survival of cells.

摘要:
Phase shift masks include axially spaced apart first and second radiation blocking layer patterns and a phase shifting layer pattern between the first and second radiation blocking layer patterns, on a phase shift mask substrate. The first and second axially spaced part radiation blocking layers can define narrow areas of the phase shifting layers so that patterns having fine linewidths and improved resolution can be formed on integrated circuits. Phase shifting masks can be fabricated by forming a first radiation blocking layer pattern on a phase shift mask, blanket forming a phase shifting layer and a second radiation blocking layer, patterning the second radiation blocking layer and patterning the phase shifting layer.

A photomask that is capable of implementing off-axis illumination (OAI), and a method of fabricating the same, are provided. The photomask includes a transparent substrate, a plurality of opaque patterns formed on the front surface of the transparent substrate, for defining a floodlighting portion for forming patterns, and a plurality of phase gratings formed on the back surface of the transparent substrate, allowing off-axis illumination (OAI) of an incident light source beyond the OAI limit of exposure equipment, allowing use in the outmost region of an aperture, and allowing modified illumination having a shape suitable for the layout of the opaque patterns.
