    Abstract: An apparatus monitoring semiconductor manufacturing equipment includes; an optical detector, a light generator generating light along a first optical path towards a semiconductor substrate, wherein upon irradiating the semiconductor substrate, the light becomes reflected light along a second optical path away from the semiconductor substrate and towards the optical detector, a first grating reticle between the light generator and the semiconductor substrate and including first slits having a first pitch and second slits having a second pitch different from the first pitch, a second grating reticle between the semiconductor substrate and the optical detector and including third slits having a third pitch different from the first pitch and the second pitch, wherein the optical detector determines a positional attribute of the semiconductor substrate in relation to a first pattern and a second pattern, the first pattern corresponds to a first portion of light/reflected light sequentially passing through the first slits and the third slits, and the second pattern corresponds to a second portion of light/reflected light sequentially passing through the second slits and the third slits.

    Abstract: A host system includes a connector having a structure connected to the device irrespective of a direction. The connector includes a plurality of pins disposed thereon. A connection direction detector is configured to detect a direction in which the device is connected to the host system by detecting a signal from at least one first pin of the plurality of pins. A setting controller is configured to receive, from the device, setting information related to a configuration supported by the device and control a configuration operation on the device based on direction information from the connection direction detection. The host system is configured to perform control such that a function module having a unique function included in the device is selectively enabled based on the setting information and the direction information.
