Abstract: An optical disk includes: a data region; and a management region. The data region stores: at least one video object containing video information and audio information; and at least one audio object containing audio information. The management region stores first path information and second path information, the first path information indicating a first reproduction path including only the at least one video object, and the second path information indicating a second reproduction path including a combination of the at least one video object and the at least one audio object.

Abstract: In one embodiment, the present invention relates to a method of making a carbonized antireflection coating involving the steps of depositing a polymer layer on a semiconductor substrate; and carbonizing at least a portion of the polymer layer in an inert atmosphere to provide the carbonized antireflection coating. In another embodiment, the present invention relates to a method of improving critical dimensional control during lithography, involving the steps of providing a semiconductor substrate; depositing a polymer layer on the semiconductor substrate; carbonizing at least a portion of the polymer layer in an inert atmosphere to provide a carbonized antireflection coating; depositing a photoresist over the carbonized antireflection coating; and patterning the photoresist.
