摘要:
The present invention relates to a defect inspection apparatus for a phase shift mask that is capable of detecting phase shifter defects that cannot be detected by conventional inspection techniques, by a simple method using an optical method and a comparison of electric signals. In a defect inspection apparatus for a phase shift mask having a phase shifter pattern provided on a mask transparent substrate 1, after the phase shifter pattern has been formed, a phase shifter defect inspection is performed from the mask transparent substrate 1 side of the phase shift mask 1. To perform the defect inspection, light 12 is applied to the phase shift mask 1 from the mask transparent substrate 1 side thereof, and reflection images of at least two different phase shifter pattern fabricated regions are captured by photoelectric conversion light-receiving elements 15a and 15b. The respective image signals 17 and 18 of the reflection images are compared with each other to detect a defect on the mask from the difference between the signals.

The disclosure relates to a semiconductor device comprising silicon having a substrate composed of low grade silicon, a silicon layer whose silicon purity is higher than that of the low grade silicon formed on the substrate and an electrode formed on the silicon layer. In the device, the low grade silicon may be selected from metallurgical grade silicon and silicon whose purity is less than 99.99%, and the silicon layer may be over 99.999% purity or semiconductor grade.
摘要:
Described is a process for the preparation of Compound (7) in accordance with the following reaction scheme by reacting Compound (5) with ethylene glycol in a solvent in the presence of a Lewis acid, thereby obtaining Compound (6), and then reacting the resulting compound with a carbonate diester in a solvent in the presence of a metal alkoxide (R1, R6 each represents a C1-6 alkyl group or the like and R5 represents H or C1-5 alkyl group). Compound (7) so obtained is useful as an intermediate for camptothecins useful as antitumor agents.

A photovoltaic device includes an i-type amorphous silicon thin film and a p-type amorphous silicon thin film arranged on portions of an n-type crystalline silicon substrate, a collecting electrode arranged on the amorphous silicon thin film, and an insulating layer arranged around the portions where the amorphous silicon thin film is formed. Thus, a pin junction is formed only below the collecting electrode.

An ion beam I is irradiated from an ion gun 10 onto a sample S on an XY stage 100, and an electron shower E is irradiated onto the sample S. Electrification of the sample by ion is neutralized by irradiation of the electron shower E. In the case of adjusting the electron shower E, a drive system 200 is driven by a control signal from a control unit 300 to scan a spot of the electron shower E by a Faraday cup F positioned at a corner of the XY stage 100. Detected current values of the Faraday cup F at respective scanning positions are amplified at an amplifier 210. The current values thus amplified are digitized at an A/D converter 220, and are then delivered to the control unit 300. The control unit 300 displays the intensity distribution of the electron shower E obtained by this scanning on a display unit 400.

A semiconductor device according to the present invention comprises a semiconductor thin film, and first and second insulator films formed in such arrangement that the semiconductor thin film being sandwiched therebetween. First and second graded layers each containing a constitutent element of the semiconductor thin film and impurities and having a content of the impurities decreased in the direction of the semiconductor thin film are interposed between the semiconductor thin film and the respective insulator films, thereby to relax internal stress produced in the junction interfaces of the semiconductor thin film and the insulator films and to prevent cracking from occurring in the junction interfaces.
