Definitions
- the present invention relates generally to a method of forming an antireflective silicon oxynitride (SiON) film on a surface of a semiconductor substrate and more particularly such an antireflective film which is non-polluting vis-à-vis resins photoresist, and more specifically photoresist resins for far ultraviolet or chemically amplified, used during the manufacturing process of semiconductor devices such as integrated circuits.
- SiON silicon oxynitride
- the present invention therefore relates to a method of forming on a semiconductor substrate an antireflective film of non-polluting silicon oxynitride vis-à-vis photoresist resins, in particular for photolithography in far UV and which avoids the contamination of antireflective deposits of silicon oxynitride formed in the same reactor on successively introduced substrates.
- the method for forming on each of a series of silicon semiconductor substrates successively introduced into the same chamber of a reactor, an anti-reflective film of silicon oxynitride, non-polluting with respect to screw photoresist resins for far UV comprises a step of plasma assisted chemical vapor deposition (PECVD) of an antireflective film of silicon oxynitride and the treatment of the antireflective film with an oxygen plasma, said method being characterized by the fact that before the successive introduction of each of the substrates, the reactor chamber is cleaned by: a) a step of purging the reactor chamber using an oxygen-free gas plasma; then b) a step of blank deposition of silicon oxynitride by chemical vapor deposition assisted by plasma from precursor gases.
- PECVD plasma assisted chemical vapor deposition
- the gas used is a fluorinated gas such as CF 4 , C 2 F 6 , NF 3 and SF 6 , preferably CF 4 .
- the conditions for producing the plasma are moreover conventional.
- the duration of this purge step (a) is generally from 10 to 60 seconds.
- This purging step is essential, since it makes it possible to consume almost all of the residual oxygen in the chamber following the treatment of a previous substrate.
- Step (b) of blank deposition of silicon oxynitride is carried out under the same conditions as the conventional deposition of the anti-reflective film of SiON.
- N 2 0 and SiH 4 with the appropriate flow rates, and a high frequency generator operating for example at 380 kHz.
- the duration of the blank deposit is generally of the order of 1 to 60 seconds.
- This blank deposition step makes it possible to fix the particles remaining in the chamber on the walls of the reactor chamber.
- the deposition of the anti-reflective SiON film takes place under the same conditions and its duration is determined so as to obtain a layer of desired thickness, generally of the order of 15 to 30 nm.
- the oxygen plasma treatment is conventional.
- the same HF generator as before can be used to create the oxygen plasma.
- the duration of treatment can vary from a few seconds to 1 minute or more, but is generally from 10 to 60 seconds and also depends on the power of the HF generator.
- the effect of oxygen plasma on the SiON film was measured using a spectroscopic ellipsometer and by measuring the etching rate in hydrofluoric and orthophosphoric acid baths.
- the SiON film treated with oxygen plasma can be eliminated by successive soaking in a dilute HF solution (approximately 30 s) and soaking in an H 3 P0 4 solution.
- This withdrawal is selective with respect to the gate oxide and is integrated with respect to the active zone.
- the device can then be cleaned in the conventional way using a SCI solution (H 2 0 2 / NH 4 OH), rinsing with deionized water and drying before re-oxidizing the grid (approximately 10 minutes) and at the spacers depot.
- a SCI solution H 2 0 2 / NH 4 OH
