The techniques are called soft lithography because the tool they have in common is a block of polydimethyl-siloxane (PDMS)—the rubbery polymer used to caulk the leaks around bathtubs. (Physicists often refer to such organic chemicals as “soft matter.

这类技术称为软蚀刻术，因为其中共有的工具是一块聚二甲基矽氧烷（PDMS），这是一种用来填塞浴缸裂缝的橡胶聚合物（物理学家通常称这种有机化学材料为「软物质」）。
