Title: X-ray reduction projection aligner
Inventor: OTANI MASAYUKI
IPC: H01L21/027
Filed: 1996-09-19
Abstract: PROBLEM TO BE SOLVED: To provide an X-ray reduction projection aligner which can be shortened in exposing time and can be improved in productivity. SOLUTION: X rays from an X-ray source 1 are condensed to a mask 3 by reflecting the X rays with a multilayered film mirror 2. The X-ray image of a pattern formed on the mask 3 is formed on a wafer 5 after reducing the image through a reducing optical system 4. Since the X-ray source 1 emits not only the X rays, but also ultraviolet rays and visible light, the wafer 5 is also irradiated with the ultraviolet rays, etc. The quantity of the energy of the ultraviolet rays, etc., is adjusted to a value smaller than the threshold at which the component of a resist on the wafer 5 changes. Since the energy is given to the resist by a quantity which is smaller than the threshold when the resist is irradiated with the ultraviolet rays, etc., almost all energy of the X rays can be utilized for the formation of a pattern.

Title: Manufacture of lithium ton secondary battery
Inventor: KAWAMOTO KOJI
IPC: H01M10/05
Filed: 1997-10-01
Abstract: PROBLEM TO BE SOLVED: To form a stable SET on a negative electrode surface, reduce irreversible capacity, and improve a cycle characteristic by performing first time charge at least under one condition among charge in a cooling atmosphere and low electric current charge, and forming an SEI coating film having specific capacitance on the negative electrode surface. SOLUTION: When a charging time temperature is lowered from the relationship between the charging time temperature and irreversible capacity, the irreversible capacity can be reduced. Therefore, it is effective to perform first time charge in a cooling atmosphere, that is, at a low temperature not more than 20 deg.C or perform charge by a low electric current not more than 1 C. The irreversible capacity sharply reduces when capacitance by an SET is not more than 0.4 mF/cm<2> from the relationship between the capacitance of the SET and the irreversible capacity. Then, an SEI coating film having capacitance not more than 0.4 mF/cm<2> is formed on a nagative electrode surface, a quantity of the SET formed on the negative electrode surface reduces, and the irreversible capacity is reduced, and since the generating SET is stable, a cycle characteristic can also be improved.
