Abstract:
1. A warp correction apparatus that corrects a warp of a semiconductor element substrate, the warp correction apparatus comprising: an injection mechanism having a nozzle that performs injection treatment of injecting an injection particle to a rear surface that is opposite to a principal surface or opposite to a film surface in the semiconductor element substrate; an adsorption table that adsorbs the principal surface or the film surface of the semiconductor element substrate to hold the semiconductor element substrate; a moving mechanism that moves the adsorption table so that the semiconductor element substrate relatively moves with respect to an injection area of the injection particle by the nozzle; an injection treatment chamber that houses the semiconductor element substrate held on the adsorption table and in an interior of which injection treatment is performed; a measurement mechanism that measures a warp amount of the semiconductor element substrate; and a control device that, based on a difference between a previously set target warp amount and a warp amount of the semiconductor element substrate measured by the measurement mechanism, performs at least either one of a setting processing of an injection treatment condition of the injection mechanism and an accept/reject determination of the semiconductor element substrate for which injection treatment has been performed.
