Publication number: 20020031917Abstract: When laser ablation is implemented with respect to a target comprising silicon in an atmosphere containing oxygen, Si constituting the target is ejected from the laser irradiated portion thereof. The ejected Si collides with oxygen, which is the atmosphere gas, and reacts therewith in a gas phase forming clusters composed of SiO2 or SiOx, or silicon (Si) and oxygen, and containing pores with a size of several nanometers. The clusters adhere to the substrate, thereby forming a porous film composed of Si and oxygen and containing pores on the substrate. Furthermore, an insulating film for a semiconductor element is formed to have a multilayer structure in which an aggregate is deposited on the substrate and then a dense film is formed. When the insulating film is formed, the aggregate is produced by implementing laser ablation under a pressure of 1 Kpa, for example.Type: ApplicationFiled: September 6, 2001Publication date: March 14, 2002Inventors: Takashi Nire, Akira Matsuno, Kazuhiro Kagawa, Mika Mukoujima

Publication number: 20020024978Abstract: When it is determined that a pulse width of high harmonic light Lb to jitter of discharge light Ld is not appropriate as a result of comparison between a waveform of the discharge light Ld and that of the high harmonic light Lb, a main controller judges that the jitter of the discharge light Ld in a gas laser device is large, and controls to move a translating stage to extend a cavity length so to increase a pulse width of fundamental harmonic light La which is laser-oscillated by an oscillator. When the main controller determines that a light intensity of the high harmonic light Lb has a value smaller than a predetermined value and is not normal, it controls to move the translating stage to shorten the cavity length so to enhance the light intensity of seed light La to be laser-oscillated by the oscillator. Thus, the light intensity and pulse width of the seed light at injection locking are optimized.Type: ApplicationFiled: August 17, 2001Publication date: February 28, 2002Inventors: Yoshihiko Inagaki, Kazuaki Sajiki, Takashi Nire

Patent number: 5542979Abstract: A thin sulfide film can be formed by simultaneously generating under different conditions a plurality of deposition materials to be deposited on a substrate, using the fact that sulfur has a higher vapor pressure. Sulfur vapors can be generated in an external vessel (6) which is located outside the vacuum deposition vessel (1). The sulfur vapors can then be introduced into the vacuum deposition vessel (1) through a vapor inlet tube (7) to form a localized atmosphere of sulfur vapors within the vacuum deposition vessel (1) in the vicinity of the substrate which is positioned on a substrate holder (4). Chemical bonding, on the substrate, of the sulfur vapors and the vapors of other deposition materials generated from other deposition sources provided in the vacuum deposition vessel (1) form a thin film of high quality with good reproducibility.Type: GrantFiled: May 9, 1995Date of Patent: August 6, 1996Assignee: Kabushiki Kaisha Komatsu SeisakushoInventors: Akira Matsuno, Takashi Nire

Patent number: 5311035Abstract: A thin film EL element capable of emitting light of different colors desired even at a low applied voltage owing to its high luminescent efficiency and freedom from crystal defects. The thin film EL element is of the dual dielectric structure having a transparent substrate (1), and a transparent conducting film (2), a first dielectric layer (3), a luminescent layer (4), and a second dielectric layer (5), which are formed on top of the other on the substrate, the transparent conducting film and the second dielectric layer being provided with respective electrodes (6a, 6b). It is characterized in that the luminescent layer has a superlattice structure represented by (luminscent host material)/(luminescent host material):(luminescent center impurity). The luminescent layer permits the doping of various luminscent center impurities while keeping its electrical neutrality without a need for the addition of charge compensating elements.Type: GrantFiled: March 2, 1992Date of Patent: May 10, 1994Assignee: Kabushiki Kaisha Komatsu SeisakushoInventor: Takashi Nire
