- Example '46 12 0.008 0.05 rice cake ⁇
- the solvent of the present invention has excellent solubility in polysilazane, excellent edge-cutting properties, has no adverse effect on the underlying semiconductor or substrate, and has no effect on the properties of the residual polysilazane coating film. Since it does not give, it is suitable as a solvent for polysilazane treatment.
- the solvent of the present invention does not contain a group that decomposes polysilazane and has an extremely low water content, so that clogging of the waste liquid line can be prevented. Cleaning work can be reduced by reducing the number of times, and the amount of silane and other gases generated in the waste liquid tank can be reduced, resulting in excellent safety.
- a polysilazane-treated solvent having excellent safety for the human body can be provided. Furthermore, by treating polysilazane using this solvent, it is possible to provide a safe and inexpensive method for treating polysilazane that uses a small amount of solvent, has little effect on the properties of the base material, and has little effect on the residual film. You. Industrial applicability
- the polysilazane-treated solution of the present invention is used for forming a polysilazane film used as an interlayer insulating film, a planarization film, a passivation film, an inter-element isolation insulator, or the like of a semiconductor device such as an LSI or a TFT liquid crystal display device. It is suitably used as an edge rinse liquid, a back rinse liquid at the time of coating formation, a cleaning liquid for a coating apparatus, and a cleaning liquid for a polysilazane film used as a dielectric film, an insulating film, and a partition wall film of PDP.
