    Abstract: 검사장치(100)는기판상에서타겟의파라미터를측정하기위해이용된다. 가간섭성방사선은타겟(T)을조명하기위한조명경로(실선표시된광선)를따른다. 집광경로(파선표시된광선)는타겟으로부터회절방사선을집광하여록-인이미지검출기(112)에전달한다. 기준빔은기준경로(점선표시된광선)를따른다. 음향-광학변조기(108)는록-인검출기에서의방사선의세기가기준방사선의주파수와회절방사선의주파수사이의차이에대응하는특성주파수를갖는시변성분을포함하도록기준빔의광 주파수를시프트한다. 록-인이미지검출기는시변성분의진폭및 위상모두를나타내는 2차원이미지정보를기록한다. 상이한시프트(110)를갖는제2 기준빔은제2 기준경로(쇄선표시된광선)를따른다. 2개의기준빔들사이의간섭이세기정규화를위해이용될수 있다.

    Abstract: PURPOSE: Provided are a lithography apparatus comprising an alignment subsystem, a method for preparing a device and an alignment structure to improve the capture range of a periodic alignment system and robustness. CONSTITUTION: The lithography apparatus comprises a supporting structure which supports the patterning means patterning the projected beam of radiation according to a desired pattern; a substrate table which holds a substrate(W) provided with an alignment structure having spatially periodic optical properties; and an alignment subsystem(21) which aligns the substrate to the pattern means, wherein the alignment subsystem(21) comprises an optical device(20, 24, 26) which optically treats the light reflected from the alignment structure or transmitted by the alignment structure to produce a measuring light whose intensity is changed according to the reference position defined to the patterning means and the relative position of the spatially periodic alignment structure; a sensor which is connected with an optical interference device for measuring the intensity of measuring light and/or the information of phase; and an actuator(PW) which controls the relative position of the patterning means and the substrate table based on the intensity of measuring light and/or the information of phase. The alignment subsystem is aligned so as to use an aperiodic pitcher provided on the alignment structure detectable as a capture position or a check position.
