Resist pattern thickening material and process for forming the same, and semiconductor device and process for manufacturing the same

摘要

The present invention provides a resist pattern thickening material which can thicken a resist pattern and form a fine space pattern, exceeding exposure limits of exposure light used during patterning. The resist pattern thickening material contains a resin and a polyhydric alcohol. The present invention also provides a process for forming a resist pattern and a process for manufacturing a semiconductor device, wherein the resist pattern thickening material of the present invention is suitably utilized.
