    Abstract: PURPOSE: A substrate etching method for forming various stepped structures and a method for fabricating a heat-sink for a three-dimensional micro-system using the same are provided to reduce a process period of time and the manufacturing cost by simplifying a fabrication process. CONSTITUTION: The first mask pattern(112) having the first hole for exposing the first region is formed on a substrate(100). The second mask pattern(114) having the second hole for exposing the second region is formed on the first mask pattern and the first region of the substrate. The first recess region(132) is formed on the second region by etching the substrate. The second recess region(134) and the third recess region are formed by etching the substrate. The second recess region and the third recess region have different stepped structures.

    Abstract: PURPOSE: A method of through-etching substrate is provided to efficiently perform a cooling processing of a substrate and to improve a profile around a penetrated hole by using a metal material. CONSTITUTION: A buffer(62) made of a silicon dioxide is formed on a surface of a silicon substrate(50) having a hole. Then, a metal film(64) made of an aluminum is formed on the buffer(62). After depositing another buffer(72) and another metal film(74) on the rear surface of the silicon substrate(50), an etch mask pattern(66) is formed on the metal film(74). After etching the metal film(74) and the buffer(72) using the etch mask pattern(66) as an etch mask, the silicon substrate(50) is penetrated by etching using the metal film(74) and the buffer(72) as another etch mask. Due to the metal films(64,74), plasma ion flux is smoothly circulated, so that a good profile is completed.
