摘要:
A magnetic transfer master disk including a magnetic layer and exhibiting excellent shape stability of a protrusion/recess pattern is provided. An initial layer formed of a conductive film is formed on a surface of a master on which a pattern of minute protrusions/recesses is formed, and then a magnetic layer (principal layer) is formed on the initial layer, and then, a metal layer is formed by electroforming. A duplicate in which the initial layer, the magnetic layer and the metal layer have been integrated is peeled off from the master, thereby obtaining a magnetic transfer master disk, which is a duplicate in which the magnetic layer and the initial layer are deposited on the protruded/recessed surface of the metal layer.

A chemical amplification resist composition that is used for preparation of a mold, and a mold preparation method and a resist film each using the composition are provided.
摘要:
This invention accurately detects an etch amount of an etching target layer irrespective of a type of a mask layer. A light La is reflected by an upper surface of a photoresist mask layer 316 and a bottom of a hole H. Thereby a reflected light La1 and a reflected light La2 are obtained. The reflected lights La1 and La2 interfere with each other, thereby generating an interference light Lai. A light Lb is reflected by an interface between the photoresist mask layer 316 and a polysilicon film 304, and the upper surface of the photoresist mask layer 316. Thereby a reflected light Lb1 and a reflected light Lb2 are obtained. The reflected lights Lb1 and Lb2 interfere with each other, thereby generating an interference light Lbi. Using the interference lights Lai and Lbi, an etch amount of the polysilicon film 304 is calculated.
