    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.
