To provide a curable composition for nanoimprinting that can form a cured product that has a sufficiently cured surface and is less prone to a pattern collapse defect even when the curable composition is cured by a photo-nanoimprint method at a low exposure dose. To provide a nanoimprint method for forming such a cured product. To provide a cured product that is less prone to a pattern collapse defect even when cured at a low exposure dose, a method for producing such a cured product, a method for manufacturing an optical component, a method for manufacturing a circuit board, and a method for manufacturing an electronic component. A curable composition that satisfies the formula (1) in a cured state: Er 1 /Er 2 ≧ 1.10 (1) wherein Er 1 denotes the surface reduced modulus (GPa) of a cured product of the curable composition, and Er 2 denotes the internal reduced modulus (GPa) of the cured product.
摘要:
In described examples, a semiconductor device (100) has an n-type buried layer (108) formed by implanting antimony and/or arsenic into a p-type first epitaxial layer (104) at a high dose and low energy, and implanting phosphorus at a low dose and high energy. A thermal drive process diffuses and activates both the heavy dopants and the phosphorus. The antimony and arsenic do not diffuse significantly, maintaining a narrow profile for a main layer (114) of the buried layer (108). The phosphorus diffuses to provide a lightly-doped layer (120) several microns thick below the main layer (114). An epitaxial p-type layer (106) is grown over the buried layer (108).
