Abstract
A detection system configured to detect a state of a structure within a processing space of a substrate processing apparatus, includes: a detection substrate including a state detector that detects the state of the structure; a transfer device that loads and unloads each of a substrate to be processed and the detection substrate into and from the processing space; and a control device, wherein the detection substrate further includes at least one acceleration detector that detects an acceleration in each of two directions intersecting each other in a surface of the substrate, and wherein the control device estimates an orientation of the state detector on the detection substrate within the processing space based on a detection result obtained by the at least one acceleration detector when the detection substrate is moved in a loading/unloading direction during loading or unloading of the detection substrate into or from the processing space.
