Abstract: According to one embodiment, first, an embedment material is embedded between linear core material patterns in such a manner that a height thereof becomes lower than a height of each of the core material patterns. Then, a shrink agent is supplied and solidified on the embedment material. Subsequently, the solidified shrink agent and the embedment material are removed and a spacer film is formed on an object of processing. Then, the spacer film is etched-back and a spacer pattern is formed by removal of the core material patterns. The solidified shrink agent which is formed in such a manner that a width of the spacer pattern becomes narrow in a region corresponding to a position where the shrink agent, in a sectional surface vertical to an extended direction of the spacer pattern is supplied is removed.

Abstract: According to one embodiment, a first auxiliary pattern is arranged at a corner of a mask pattern, an arrangement position of a second auxiliary pattern is calculated based on an opening angle of a resist pattern to which the mask pattern is transferred, and the second auxiliary pattern is arranged at the arrangement position.

Abstract: A charging circuit that prevents a system abnormality caused by removal of a battery. The charging circuit includes a constant voltage charge controller which detects charge voltage and performs a constant voltage charging operation. A constant current charge controller detects charge current and performs a constant current charging operation. A controller controls the constant voltage charge controller to perform the constant voltage charging operation during a period from when the charge voltage reaches a fully charged voltage to when the charge current decreases to a charge completion current. The controller suspends charging the battery when the constant voltage charging operation is being performed and detects whether or not the battery is coupled to the charging circuit based on the charge voltage during the charging suspension.
