摘要:
A novel sulfonium salt having at least one substituted aromatic group having acid labile groups and at least one nitrogenous aromatic group is provided. A chemically amplified, positive resist composition comprising the sulfonium salt as well as an alkali soluble resin and a dissolution inhibitor in an organic solvent has solved the PED problem.
摘要:
Trifluoromethanesulfonic and p-toluenesulfonic acid bis- or tris(p-tert-butoxyphenyl)sulfonium salts are novel. They are prepared from bis(p-tert-butoxyphenyl)sulfoxide which is also novel. A chemically amplified positive resist composition which contains the sulfonium salt as a photo-acid generator is highly sensitive to deep-UV rays, electron beams and X-rays, can be developed with alkaline aqueous solution to form a pattern, and is thus suitable for use in a fine patterning technique.

摘要:
The invention provides a novel sulfonium salt having a substituted or unsubstituted arylsulfonate anion. The novel sulfonium salt minimizes the influence of deactivation by basic compounds not only at a resist surface, but also at a resist-substrate interface, assists a resist to be configured to a definite pattern profile. When the sulfonium salt has an acid labile group, it is effective for increasing the dissolution contrast between exposed and unexposed areas. The sulfonium salt is useful in a chemically amplified positive resist composition which lends itself to fine patterning and features high resolution.
摘要:
A polymer comprising recurring units of formula (1) is provided wherein some of the hydrogen atoms of phenolic hydroxyl groups and/or alcoholic hydroxyl groups are replaced by acid labile groups. The polymer is crosslinked within a molecule and/or between molecules with a crosslinking group having a C--O--C linkage resulting from reaction of some of the remaining phenolic hydroxyl groups and/or alcoholic hydroxyl groups with an alkenyl ether compound or halogenated alkyl ether compound. The amount of the acid labile group and the crosslinking group combined is on the average from more than 0 mol % to 80 mol % of the entirety of the phenolic hydroxyl group and alcoholic hydroxyl group. The polymer has Mw of 1,000-500,000. ##STR1## R.sup.1 is H or methyl, R.sup.2 is C.sub.1 -C.sub.8 alkyl, letter x is 0 or a positive integer, y is a positive integer, x+y.ltoreq.5, letters p and q are positive numbers satisfying p+q=1 and 0

A panoramic image is to be easily generated.A driver 12 displaces at least one of a lens unit 11a and an image capturing element 21 with respect to an optical axis. A control unit 50 displaces, using the driver 12, at least one of the lens unit 11a and the image capturing element 21 in accordance with a motion of an image capturing apparatus 10. When generating a plurality of captured images while shifting an image capturing direction in order to generate a panoramic image from the plurality of captured images, the control unit 50 changes a position of the lens unit 11a and/or the image capturing element 21, the position being a position at the start of exposure of each of the captured images, in a direction set according to a direction in which the image capturing direction shifts, thereby performing correction of deviation caused by a motion of the image capturing apparatus.
摘要:
An imaging apparatus is disclosed. The imaging apparatus includes an image capturing section, a motion detecting section, a reliability determining section, a shaking compensating section, and a filtering section. The image capturing section captures a plurality of images which chronologically differ. The motion detecting section detects motion of the plurality of images and generates motion information. The reliability determining section determines reliability of the motion information. The shaking compensating section compensates shaking which takes place among the plurality of images corresponding to the motion information. The filtering section filters an image which has been compensated for shaking by using a recursive filter. A characteristic of the filtering section is varied corresponding to the reliability of the motion information.
