激光诱导正面蚀刻 (LIFE) 是一种用于电介质纳米精度结构的方法,例如电介质。熔融石英,使用薄金属和有机吸收层附着在样品的激光照射正面。使用波长为248nm、脉冲持续时间为25ns的准分子激光器作为激光源。对于亚微米图案化,由史瓦西物镜投射由顶帽激光束照射的相位掩模。 LIFE 工艺可以制造轮廓分明且光滑的表面结构,具有亚微米横向蚀刻区域 (Δx < 350nm) 和垂直蚀刻深度从 1 纳米到亚毫米。
Laser-induced front side etching (LIFE) is a method for the nanometer-precision structuring of dielectrics, e.g. fused silica, using thin metallic as well as organic absorber layer attached to the laser-irradiated front side of the sample. As laser source an excimer laser with a wavelength of 248nm and an pulse duration of 25ns was used. For sub-μm patterning a phase mask illuminated by the top hat laser beam was projected by a Schwarzschild objective. The LIFE process allows the fabrication of well-defined and smooth surface structures with sub-μm lateral etching regions (Δx < 350nm) and vertical etching depths from 1nm to sub-mm.
