Title: Semiconductor device and its manufacture
Inventor: YAMAZAKI YASUSHI
IPC: H01L21/768
Filed: 1996-08-15
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration of step coverage at the contact hole by not allowing insulation film thickness on a substrate at the peripheral circuits to become excessively thick on the occasion of flattening the interlayer insulating film through the polishing by the CMP(Chemical Machinerry Polishing) method. SOLUTION: A first interlayer insulating film 3 is formed on a p-type silicon substrate 1 and a capacitance contact hole 4 is opened to this interlayer insulating film 3 to form a storage capacitor consisting of a capacitance lower electrode 5, a capacitance insulating film 6 and a plate electrode 7. The NSG(Non- doped Silicate Glass) film 8 and BPSG(Boron PhosphoSilicate Glass) film 9 having a higher CMP rate than that of the NSG film are grown on the entire part for the purpose of CMP. In this CMP process, the BPSG film 9 is perfectly removed in the memory cell and the NSG film 8 is polished only for the predetermined thickness. Thereby, the surface height of the second interlayer insulating film 10 becomes lower than the memory cell in the peripheral circuit, the aspect ratio of the wire contact hole 11 can be improved and coverage of aluminum wiring 12 can also be improved.

Title: Manufacture of semiconductor device
Inventor: KATANO FUMIAKI
IPC: H01L21/3213
Filed: 1984-10-15
Abstract: PURPOSE:To form a side wall uniformly even when the etching rate of a material for the side wall disperses by using CF4 as an etching gas and specifying gas pressure on etching. CONSTITUTION:In the manufacture of a semiconductor device in which a second insulating film is etched in an anisotropic manner through reactive ion etching and the second insulating film is left only on the side surface of a metallic layer, CF4 is employed as an etching gas, and gas pressure on etching is brought to 25Pa or less from 3Pa or more. Since the form of a side wall does not change even when an etching time is lengthened at that time, the shape of the side wall can be formed uniformly even when there is dispersion in the etching rate of a material for the side wall in an etching device or a wafer, thus improving the characteristics and yield of the semiconductor device such as a Schottky- barrier junction gate type field-effect transistor.

Abstract: PURPOSE:To prevent a solid-state laser device from being distorted in oscillation beam pattern and deteriorating in oscillation efficiency by a method wherein a thermal conductor is provided in close contact with the side face of a laser medium, and a cooling means is provided to cool down the laser medium and the thermal conductor. CONSTITUTION:Exciting light emitted from an exciting lamp 7 is reflected by a reflecting mirror 8 and absorbed by a laser medium 1, and the optical energy of the exciting light is partially taken outside of the laser medium as a laser beam through resonator mirrors 9 and 10. At the oscillation of this laser, a part of the optical energy of the exciting light absorbed by the laser medium 1 not conductive to laser oscillation is converted into thermal energy and releases heat in the laser medium 1, so that the laser medium 1 which absorbs the released heat is cooled by a coolant 4 which circulates in a flow path 5. A thermal conductor 32 is provided in close contact with the side face of the laser medium so as to prevent the laser medium from constituting a thermal lens due to the temperature distribution concerned. Therefore, the conductor excellent in thermal conductivity removes heat released at the close contact area, so that a solid-state laser device whose laser beam is excellent in quality can be obtained.
