Title: Method and apparatus of depositing aluminum for filling holes
Inventor: SANG-HO YU
IPC: H01L21/285
Filed: 2000-06-28
Abstract: PROBLEM TO BE SOLVED: To fill holes perfectly so that a substrate and a metal surface have no voids and the metal surface has no recesses. SOLUTION: A layer hard to dissolve is deposited on a substrate 66 having contacts or holes formed therein, the contacts or holes having a large aspect ratio. A PVD(physical vapor deposition) metal-deposited layer, e.g. PVD Al or PVD Cu is deposited on the layer hard to dissolve under the pressure of 1 milli Torr or lower to give a conformal PVD metal-deposited layer. Thereafter, the holes or contacts are filled with a metal, e.g. by reflowing an additional metal deposited by the PVD on the conformal PVD metal-deposited layer. This process step is preferably implemented in an integrated processing system having a long-throw PVD chamber 36, where a target 64 is separated from the substrate 66 by a long-throw distance of at least 100 mm and a hot metal PVD chamber which serves also as a reflow chamber.

Abstract: PROBLEM TO BE SOLVED: To provide a method for analyzing the structure of crystal, capable of readily judging whether a spreading shape of a peak to be measured is decided by reflecting that a composition in the crystal is distributed nonuniformaly, when evaluating the crystal structure by X-ray diffraction. SOLUTION: The method for analyzing the structure of crystal includes a step of measuring profiles of a plurality of (hkl) reflections at a symmetrically reflecting position with respect to an X-ray incident angle (θ) and converting the profiles into a difference ΔΘ (abscissa axis) from a reference point, a step of converting the abscissa axis in accordance with the formula of ΔA(hkl)=--(2 a03/λ2h2)sin 2θB1(hkl)×Δθ(hkl), a step of making a graph obtained by plotting ΔA (hkl) value of a feature point with respect to an amount (k2+12)/h2 calculated from an exponent (hkl), and a step of determining whether the graph is a straight line.  Thus, by conducting decision theoretic analysis using the graph, a reply can be simply and surely given to the problem as to whether the spreading shape of the peak occurs due to a distribution of the composition.

Title: Image forming device
Inventor: OMIYA SATOSHI
IPC: B41J2/44
Filed: 2000-07-11
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device for properly selecting two of a plurality of light beam sources which are obliquely arranged at different intervals, lighting them and forming the images of various resolutions. SOLUTION: In the image forming device 1, a plurality of LD are obliquely arranged in an LD unit at the different intervals in a main scanning direction and a subscanning direction. When a printing instruction is given, the resolution of image data just before is compared with that of image data becoming the object of the present printing instruction. When the change of resolution is required, two LD corresponding to the resolution of picture data becoming the object of the printing instruction are selected. It is judged whether two selected LD are appropriate or not from the detection result of a synchronism detection sensor and a detection result that the synchronism detection sensor is to previously detect with the above resolution. When two LD which are appropriate for the resolution are selected, a printing operation is performed by selected LD.  When the selection of two LD is mistaken, an error message is outputted and a processing is terminated (steps S101 to S105).
