A document reader comprises line sensors that are staggeredly arranged and read a white reference plate to obtain a white reference read value A, and a white reference average value AA is determined from value A for each line sensor. The line sensors read another white reference plate placed on a document support plate to obtain a white reference read value B, and a white reference read average value BB is determined from value B for each line sensor. A sensitivity effect coefficient C for each line sensor is determined by dividing BB by AA. Using the line sensors, there are obtained a document read value E for each line sensor by reading an illuminated document on the document support plate, a white reference read value Aa by reading with the white reference plate before reading the document, and a black reference read value D by reading the white reference plate under a condition that an illumination is turned off before reading of the document. Shading for the line sensors is corrected using the coefficient C, the values Aa, D and E, and a number of gradation levels for image regions corresponding to read areas of the document.

摘要:
In the liquid immersion lithography process, by simultaneously preventing deterioration of a resist film and deterioration of an immersion liquid employed during liquid immersion lithography which uses various immersion liquids, including water, resistance to post exposure delay of the resist film can be improved without increasing the number of processes, thereby making it possible to form a high resolution resist pattern using liquid immersion lithography. Furthermore, it is possible to apply a high refractive index liquid immersion medium, used in combination with the high refractive index liquid immersion medium, thus making it possible to further improve pattern accuracy. Using a composition comprising an acrylic resin component having characteristics which have substantially no compatibility with a liquid in which a resist film is immersed, particularly water, and are also soluble in alkaline, a protective film is formed on the surface of a resist film used.
摘要:
A liquid immersion lithography process is provided. In particular, the liquid immersion lithography process is one in which the resolution of a resist pattern is improved by exposure to light through a liquid having a refractive index higher than that of air and a predetermined thickness, while being arranged on at least a resist film in a pathway allowing exposure light for lithography to reach to the resist film. Accordingly, both the resist film and the liquid used are prevented from deterioration in liquid immersion lithography. Thus, the formation of a high-resolution resist pattern can be attained with liquid immersion lithography. Therefore, the liquid comprised of a silicon-based liquid transparent to exposure light used in the lithography process is employed as an immersion liquid for liquid immersion lithography.

A semiconductor device has a configuration in which more than three kinds of wells are formed with small level differences. One kind of well from among the more than three kinds of wells has a surface level higher than other kinds of wells from among the more than three kinds of wells. The one kind of well is formed adjacent to and self-aligned to at least one kind of well from among the other kinds of wells. The other kinds of wells are different in one of a conductivity type, an impurity concentration and a junction depth, and include at least two kinds of wells having the same surface level.

Provided are a polymer compound having high transparency for use in a photoresist composition for microfabrication of the next generation, a resist composition using the polymer compound as a base polymer, and a dissolution inhibitor agent composed of the polymer compound.To ensure etching resistance, an alicyclic group is introduced into a side chain portion. Hydrogen atoms on the ring of the alicyclic group are highly fluorinated to ensure transparency to light of 157 nanometer wavelength, represented by an adsorption coefficient equal to or less than 3.0 μm−1. As the alicyclic group, a polycyclic group is preferably used. Hydrogen atoms are highly fluorinated by preferably substituting all hydrogen atoms on the ring by fluorine atoms, that is, forming a perfluoroalicyclic group. The resist composition is formed by using the polymer compound as a base polymer and further, the dissolution inhibitor agent is formed of the polymer compound.
