Title:
METHOD FOR PROCESSING OBJECT TO BE PROCESSED
Document Type and Number:
WIPO Patent Application WO/2017/204159
Kind Code:
A1
Abstract:
In a method MT according to one embodiment, before etching a layer to be processed J1 of a wafer W to be processed, a main surface J11 of the layer to be processed J1 is divided into a plurality of areas ER, then, in a step SB2, the difference value between the groove width of a mask J2 provided on the layer to be processed J1 and a reference value for said groove width is calculated for each of the plurality of areas ER, in a step SB6, correspondence data DT indicating correspondences between the temperature of the layer to be processed J1 and the thickness of a formed film is used to adjust the temperature of the layer to be processed J1 so as to attain the necessary temperature for forming a film having a thickness corresponding to the difference values in each of the areas ER, and then a film formation process similar to the ALD method is used to form a film on the mask J2 in each atomic layer, and a film J3 having a thickness corresponding to the difference value is formed on the mask J2 so as to correct the groove widths in each of the areas ER to the reference values.
