Claim Text:
1. A warp correction method for a semiconductor element substrate using a warp correction apparatus for a semiconductor element substrate including a measurement mechanism that measures a warp amount of the semiconductor element substrate, a control device that, based on a difference between a previously set target warp amount and the 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 an injection mechanism and an accept/reject determination of the semiconductor element substrate for which injection treatment has been performed, and the injection mechanism having a nozzle that performs injection treatment of injecting to a rear surface that is opposite to a principal surface or opposite to a film surface in the semiconductor element substrate, the warp correction method comprising: a step of measuring the warp amount of the semiconductor element substrate by the measurement mechanism; a step of setting the injection treatment condition of the injection mechanism based on the difference between the warp amount measured by the measurement mechanism and the previously set target warp amount; a step of performing the warp correction processing by injecting the injection particle toward the rear surface that is opposite to the principal surface or opposite to the film surface of the semiconductor element substrate on the injection treatment condition; and a step of determining whether the warp amount of the semiconductor element substrate for which the warp correction processing has been performed is no more than the previously set target warp amount.
