摘要:
In a state where a silicon base material (1) is used as an anode, a fine platinum member (2) is used as a cathode, and an electrolyte solution (4) is arranged between the anode and the cathode, anodic oxidation is performed in constant current mode under the conditions where porous formation mode and electrolytic polishing mode coexist. The platinum member (2) is fitted in the silicon base material (1) with silicon elution, and processes such as hole making, cutting, single-side pressing are performed. Since the silicon base material can be processed at a room temperature with small energy, the crystal quality of the processing surface is not deteriorated. Thus, efficient and highly accurate processing can be performed without using a mechanical method, which consumes much material in conventional processes such as cutting of solar cell silicon base material, and without using laser whose energy unit cost is high, and furthermore, without leaving a crystal damage on a processed surface.

摘要:
A porous silicon structure is stabilized by anodically oxidizing the structure and then subjecting it to chemical functionalization to protect non-oxidized surface regions, preferably in the presence of 1-decene under thermal conditions. This process creates a protective organic monolayer on the surface of the structure, rendering it highly stable.
