Abstract: According to one embodiment, a magnetic memory device includes a first member, a first memory cell, and a controller. The first member includes first, second, and third regions. The first memory cell includes first and second magnetic layers, and a first nonmagnetic layer. The second magnetic layer is provided between the third region and the first magnetic layer. The first nonmagnetic layer is provided between the first and second magnetic layers. The controller is electrically connected to the first and second regions, and the first magnetic layer. The controller programs first information to the first memory cell by setting the first magnetic layer to a first electric potential. The controller programs second information to the first memory cell by setting the first magnetic layer to a second electric potential. The second electric potential is different from the first electric potential. The second information is different from the first information.

Abstract: There is disclosed a dose monitor method comprising illuminating a mask with illumination light, which is disposed in a projection exposure apparatus and in which a dose monitor pattern is formed, passing only a 0th-order diffracted light through a pupil surface of the projection exposure apparatus in diffracted lights of the dose monitor pattern, and transferring a 0th-order diffracted light image of the dose monitor pattern onto a substrate to measure dose, wherein during the illuminating, a center of gravity of the 0th-order diffracted light image passed through the dose monitor pattern on the pupil surface of the projection exposure apparatus is shifted from an optical axis of the projection exposure apparatus.
