In an apparatus using an intensity-modulated light for detection of spatial information based upon light intensity of light reflected from a target space, a timing synchronization circuit is provided to synchronize a phase of the intensity-modulated light from a light-emitting element with a timing of operating a light-receiving element receiving the intensity-modulated light. The light-receiving element is caused to operate for enabling the detection of intensity of the received light for each of a plurality of phase regions within one cycle of the intensity-modulated light. The timing synchronization circuit functions to compare a cyclic variation determining the operation of the light-receiving element with a cyclic variation associated with an output from a light-emitting element driving circuit in order to keep a constant phase difference between these two cyclic variations.

In order to make it possible to reduce the occurrence of physical damage to wafers during conveyance, a state is established in which wafers W are contained in a wafer cassette 1 standing approximately vertically, and the wafer cassette 1 is conveyed, in this state in which the wafers W are contained in the wafer cassette 1 standing approximately vertically, so that the planes of the wafers W are approximately parallel to the direction of conveyance. Since the wafers are kept in the state of standing approximately vertically, it is possible to reduce the occurrence of bending, as happens when they are held horizontally. Moreover, since the wafer cassette 1 is conveyed while keeping the planes of the wafers approximately parallel to the direction of conveyance, accordingly it is possible to reduce the increase of weight which acts upon the wafers W in the direction perpendicular to their planes caused by acceleration due to vertical shifting, horizontal shifting, or vertical vibration; and therefore it is possible to reduce the occurrence of bending of the wafers W.

Disclosed is a method for measuring a profile using a device for measuring the profile in which included are: a distance measuring means 2 for measuring the distance to an edge region of a semiconductor wafer 12 in such a manner that light is emitted to be reflected at the edge region and to be detected; a first swing mechanism swingably supporting the distance measuring means 2; and a second swing mechanism swingably supporting the first swing mechanism, the method comprising the steps of: locating angles of the first swing mechanism each of which gives a maximum intensity of received light at each of predetermined angles of the second swing mechanism thereof; calculating contour points using coordinate transformation, thereby enabling points-related data to be acquired to represent a contour profile of the edge region. Thus, the method can be used for edge profile measurement of large-diameter wafers.

A charged particle beam drawing apparatus forms a map having meshes, forms representative figures, area of each representative figure in each mesh being equal to gross area of figures in each mesh, and calculates a proximity effect correction dose of the charged particle beam in each mesh on the basis of area of each representative figure in each mesh. If it is necessary to change the proximity effect correction dose of the charged particle beam for drawing at least one pattern corresponding to at least one figure, the charged particle beam drawing apparatus changes area of the at least one figure before the representative figures are formed by a representative figure forming portion, and changes the proximity effect correction dose of the charged particle beam for drawing the at least one pattern corresponding to the at least one figure, calculated by a proximity effect correction dose calculating portion.
