    摘要: Non-telecentric illuminating light obtained by controlling the shape of an opening of an illumination aperture is directed onto a photomask, and a characteristic such that an image of a pattern of the photomask formed by the non-telecentric illumination moves in the direction perpendicular to an optical axis when an image-forming plane is moved in the direction of the optical axis, to perform focus monitoring. This eliminates the need for a special photomask, so that inexpensive and highly precise focus monitoring method, focus monitoring apparatus, and a method of manufacturing a semiconductor device can be obtained.

    摘要: A reticle that allows deviation in rotation and magnification of an exposure region detected just using a wafer subjected to exposure and development without having to provide an underlying pattern, a pattern transferred using such a reticle, and a correction method are achieved. A first measurement pattern is provided on a dicing line pattern of the X axis direction. Also, a second measurement pattern is formed on a line of extension of the first measurement pattern in the Y axis direction. Similarly, a third measurement pattern is formed on the dicing line pattern in the Y axis direction. A fourth measurement pattern is provided corresponding to the third measurement pattern.

    摘要: A focus monitoring method of the invention is characterized by transferring the pattern of a photo mask for phase shift focus monitor onto a photoresist on a semiconductor substrate by using modified illumination. Photo mask for phase shift focus monitor has first and second light transmitting portions which are adjacent to each other while sandwiching a shielding pattern, and is constructed so that a phase difference other than 180 degrees occurs between exposure light passed through the first light transmitting portion and exposure light passed through the second light transmitting portion. Consequently, a focus monitoring method, a focus monitor system, and a semiconductor fabricating method with high detection sensitivity in the z direction and which do not require changing of an illumination aperture can be achieved.
