ABSTRACT:
The disclosure concerns a manufacturing method of a semiconductor device includes dry-etching a semiconductor substrate or a structure formed on the semiconductor substrate; supplying a solution onto the semiconductor substrate; measuring a specific resistance or a conductivity of the supplied solution; and supplying a removal solution for removing the etching residual material onto the semiconductor substrate for a predetermined period of time based on the specific resistance or the conductivity of the solution, when an etching residual material adhering to the semiconductor substrate or the structure is removed.
