Definitions
- the present invention relates to a substrate detergent composition.
- a 3-dimensional semiconductor-mounting technology is capable of producing a semiconductor obtained by laminating thinned semiconductor chips in a multilayered structure by wire-connecting the same using through silicon vias (TSV).
- TSV through silicon vias
- a system proposed in a substrate-thinning process can be subjected to processes such as a backgrinding process and back side electrodes forming process by bonding a substrate in which a semiconductor circuit is formed on a support substrate such as silicon and glass using an adhesive.
- a support substrate such as silicon and glass
- an adhesive is necessary to readily exfoliate the support substrate after completion of the processes, and thereafter it is necessary to remove an adhesive remaining on a substrate surface in which a semiconductor circuit is formed and to complete cleaning of a thin-film semiconductor substrate surface.
- Patent Document 1 introduction of a detergent composition capable of sufficiently removing a remaining adhesive with a short period of time without corrosion of a substrate surface is strongly desired. Unfortunately, however, it did not lead to development of a detergent composition capable of sufficiently cleaning a surface of a substrate contaminated with a silicone component with a short period of time (Patent Document 1).
- Patent Document 1 Japanese Patent Laid-Open Publication No. 2013-010888
- the present invention was made in view of the above situation, and has an object to provide a substrate detergent composition used for cleaning a surface of a substrate such as a silicon semiconductor substrate, a surface of which is contaminated with e.g. a silicone component whose water contact angle is 100° or more.
- the present invention provides a substrate detergent composition used for cleaning a surface of a substrate, comprising:
- a quaternary ammonium salt 0.1 to 2.0% by mass
- B Water: 0.1 to 0.4% by mass
- C An organic solvent: 94.0 to 99.8% by mass.
- the substrate to be cleaned can be a silicon semiconductor substrate whose water contact angle is 100° or more, generally 100 to 120°.
- a content of silicon atom derived from silicone-based adhesive is generally 10% by mass or more, particularly 20% by mass or more related to the entire elements detected before cleaning taken as 100% by mass.

- a produced silicon semiconductor substrate was cleaned using detergent compositions “A” to “H”, “J” and “K”. Specifically, after the silicon semiconductor substrate was immersed in the detergent compositions “A” to “H”, “J” and “K” for 6 minutes, it was washed with pure water for one minute to execute elemental analysis on a silicon semiconductor substrate surface dried using X-ray photoelectron spectroscopy device, and analyze a content of silicon.
- Measurement device AXIS-Ultra DLD manufactured by Kratos Analytical Limited.
- Table 1 shows that in the Examples 1 to 7 that meet requirements of the substrate detergent composition of the present invention, a favorable property of cleaning can be obtained with a short period of time, resulting in no corrosion of a substrate.
- the substrate detergent composition of the present invention can obtain a favorable property of efficiently cleaning a silicon semiconductor substrate with a short period of time without corrosion of a substrate even in a thin substrate.
