Title: Lithograph projection device
Inventor: BLEEKER ARNO JAN
IPC: G03F7/20
Filed: 1999-06-29
Abstract: PROBLEM TO BE SOLVED: To provide precise beam positions by means of generating the beams of trapezoid outlines by changing the sizes or the positions of illumination beams on a mask while an illumination system periodically radiates the sub-field of the mask. SOLUTION: Beams 5a and 5b used for periodically scanning adjacent sub- fields on a mask are made into trapezoid (intensity) outlines. In a suture process, the beams 5a and 5b are shifted in a lateral direction and are overlapped in areas 6 on a wafer 4. When the beams 5a and 5b are precisely positioned, net irradiation quantity in the overlapped areas 6 is equal to irradiation quantity in a main beam part. The trapezoid outlines of the beams 5a and 5b are obtained by speedily scanning the beams 5a and 5b in a direction which is rectangular to the lengthwise direction of the sub-field. At the time of stepping the beams 5a and 5b along the lengthwise direction of the sub-field, the trapezoid outlines are obtained by movement slower than a right angle.

Title: Thermosetting resin composition
Inventor: TAKIYAMA EIICHIRO
IPC: C08F290/00
Filed: 1989-07-17
Abstract: PURPOSE:To obtain the title composition which is stable at a relatively high temperature, has excellent mechanical and electrical properties and high chemical stability, and is improved in curability and processability by mixing a specified aromatic polyamide with a maleimide derivative. CONSTITUTION:A thermosetting resin is produced by adding a maleimide derivative (e.g. N-phenylmaleimide or N,N'-diphenyl-methanebismaleimide) to an aromatic polyamide oligomer terminated with an aliphatic unsaturated group and represented by formula I [wherein A and A' are each an organic residue having a radical-polymerizable terminal unsaturated group (A and A' may be the same); B and B' are each a bivalent group of CO or SO2; R1 and R2 are each a bivalent aromatic group; and (n) is 0-15] (e.g. an oligomer of formula II). While a polyamide is a heat-resistant polymer which is stable at a relatively high temperature and has excellent electrical properties, mechanical strengths and also chemical stability, one obtained from the above resin can be further increased in mechanical strengths and chemical stability at high temperatures without detriment to those properties and can be improved in curability and processability.
