StayClean301Water-soluble Additive
兼顾最高的防腐蚀性能*和微粒对策的新基准产品
*本公司产品对比防止芯片焊点的腐蚀
大口径晶圆或小芯片等在切割时间较长的状态时，由于受切削水长时间接触加工产品的影响，可能导致芯片焊点腐蚀的发生。 通过在切割水中添加StayClean301，使加工产品的表面形成极薄的保护层，防止芯片焊点的腐蚀以及因芯片焊点腐蚀而导致的键合不良。
防止轮毂刀片的腐蚀以及刀刃侧面的尖细化
和芯片焊点相同，轮毂刀片长时间和切削水接触时也可能发生腐蚀的现象。刀刃侧面的尖细化会导致切割痕变窄或刀片破损等问题。通过在切割水中添加StayClean301，使刀片的表面形成极薄的保护层，防止刀片的腐蚀。
防止微粒的附着
在使用纯水切割时，即便是Spinner清洗后还是能看到微粒的残渣。但是，通过在切割水中添加StayClean301切割时，便可防止晶圆表面的微粒附着，防止Spinner清洗后的微粒残渣。
原理
- StayClean301中的成分在工作物表面形成保护层， 有效地防止接线头腐蚀及微粒污染。
- 在离心清洗时，同时清除StayClean301成分。
StayClean注入器
通过专为StayClean而开发的StayClean注入器，即使是1000倍以上的低稀释浓度，也可实现稳定的供给。
