Entrusted joined and customized Manufacturing/Development of Polus silicon

Porous silicon is fabricated by anodic oxidation processing in a clean process. It excels in heat insulation, is nontoxic and harmless for the environment.
The silicon material is also suitable for use in the research and development of biotechnology and medical applications because of its good bio-affinity.
Quantum14 can manufacture structured silicon layers according to customer specifications. Quantum 14 commitment also includes the entrusted development or the joint development of other technologies using the wet etching technology.

1)What is porous silicon?
It is a silicon wafer that includes many pores, thus forming a micro or nano-structure. Because the holes are formed in self-organized process, the distribution of holes can be controlled. A typical structure is described in the technological introduction.

2)What are the useful features of porous silicon?
Porous silicon is bio-compatible, exhibits high heat insulating property (because of very low thermal conductivity and thermal capacity). Depending on the nano-structure, it can emit visible light or can be used for ballistic electron generation. It has properties different from vitreous metal, and plastic, and complementary use can be expected.

3)What are the applications of porous silicon?
It is suitable for cell culturing , for the maintenance of DNA and protein.
