Title: Cmp polishing method
Inventor: HOSHINO SUSUMU
IPC: B24B37/20
Filed: 2004-03-03
Abstract: <P>PROBLEM TO BE SOLVED: To provide a CMP polishing method, in which the polishing rate is high and moreover, insulation characteristics do not deteriorate by scratches in the CMP polishing method for forming an STI structure.  <P>SOLUTION: In a figure, the uneven section of an SiO<SB>2</SB>layer 2, in which the irregularities are formed on the surface is polished for making flat (b) in the state of (a). For polishing in this process, a hard material containing abrasive grains is used as a polishing pad, thus increasing the polishing rate of the uneven section. After that, the polishing pad is switched to a soft member, without containing any abrasive grains, and polishing is made by using a polishing liquid containing the abrasive grains, thus increasing the polishing rate and removing scratches generated, when the polishing pad made of a hard material containing the abrasive grains to some extent is used. While the SiO<SB>2</SB>layer 2 remains only slightly on the surface of an SiN layer 3 (c), the polishing pad is switched to a nonwoven cloth, and polishing is made until the SiO<SB>2</SB>layer 2 disappears from the surface of the SiN layer 3, by using a polishing liquid containing the abrasive grains (d).  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Title: Particle simulation method, its program, and particle simulation device
Inventor: SUZUKI CHIKASHI
IPC: H01L29/00
Filed: 2004-03-04
Abstract: <P>PROBLEM TO BE SOLVED: To perform the calculation of the Monte Carlo simulation of the trajectory of many particles stably and at high speed.  <P>SOLUTION: When carrying out the simulation of the movement of a carrier in a semiconductor, the simulation is calculated by an electric field calculated from the distribution state of the carrier and by a system scattered about according to a force imparted at random to the carrier. At this time, the electric field changes as the position distribution of the carrier is changed. By an interval setting part 52, an interval Δτ is decided and this electric field is updated. The interval setting part 52 makes the Δτ as short as possible in order to ensure precise calculation in an initial stage where the variation of the electric field is large. The updating interval is made long in a steady state after the sufficient lapse of time. Namely, the time renewal interval in the Monte Carlo calculation is made variable instead of anchoring, and the interval Δτ is set up according to the variation of the electric field.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Title: Ink-jet printer
Inventor: OGAWA MIKIO
IPC: B41J2/165
Filed: 2004-03-08
Abstract: <P>PROBLEM TO BE SOLVED: To efficiently remove bubbles stored in a bubble storing chamber.  <P>SOLUTION: An airtight space 46 is formed by adhering an exhaust cap 40 to a carriage 3. An opening/closing valve 19 is opened by an opening/closing member 50. Bubbles in the airtight space 46 are sucked by a pump 38 (an air suction means) and discharged to the atmosphere. The flow of air during discharging the bubbles is one-way traffic of reaching the outside air from the bubble storing chamber 12 via the airtight space 46 and the pump 38. Therefore, there is no risk of the intrusion of the outside air to the bubble storing chamber 12 and an ink channel. Waste of ink can be avoided compared with a method by which ink is sucked by applying negative pressure from the nozzle side of a recording head 10 and the bubbles mixed in the ink are discharged with the suction. Therefore, the time required for discharging can be shortened.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
