Abstract:
A micro-shape transcription method has preparing a mold (13) having a transcription face on which a concavo-convex pattern is formed, pressing the transcription face against a base material (14) softened by heating, then forcibly separating the mold from the base material to transcribe a reverse pattern of the concavo-convex pattern to the surface of the base material, wherein when assuming a temperature for pressing the mold against the base material as T 1 (°C), a temperature for separating the mold from the base material as T 2 (°C), thermal expansion coefficients of the mold and the base material as α a and α b , and the maximum distance between the transcription center of the transcription face and the concavo-convex pattern as d (mm), the following relations (1) and (2):T1 ≥ T2|αa - αb|·(T1 - T2)·d ≤ 4 × 10-2 are simultaneously satisfied.
