Title: Flattening treating method of semiconductor substrate
Inventor: MARUYAMA TAKASHI
IPC: H01L21/3065
Filed: 1988-06-29
Abstract: PURPOSE:To equalize the etching rates of material layers of a different kind approximately, and to flatten a substrate surface by detecting the quantity of oxygen generated as etchback progresses and varying the feed of a reaction gas in response to the change of the quantity of oxygen generated. CONSTITUTION:An Al wiring 2 is formed onto the surface of a semiconductor substrate 1, and coated with a PSG layer 3, the PSG layer 3 is coated with an organic silicone resin layer 4 and an approximately flat surface is shaped, and PSG and a resin are dry-etched. When etching progresses and one part of PSG is exposed, PSG is also etched, and oxygen is discharged. Since the oxygen is changed into plasma and the etching of the resin is accelerated, the feed of C4F8 as a reaction gas is increased in conformity with the quantity of oxygen discharged. When the feed of C4F8 is augmented, the etching rate of PSG also reduces, but the etching rate of the resin quickly decreases more than that, the difference of the etching rates generated due to the generation of oxygen is compensated, and both layers are etched at approximately the same speed.
