PRINTABLE INKS WITH SILICON/GERMANIUM BASED NANOPARTICLES WITH HIGH VISCOSITY ALCOHOL SOLVENTS

Silicon based nanoparticle inks are formulated with viscous polycyclic alcohols to control the rheology of the inks. The inks can be formulated into pastes with non-Newtonian rheology and good screen printing properties. The inks can have low metal contamination such that they are suitable for formi...

Zusammenfassung:Silicon based nanoparticle inks are formulated with viscous polycyclic alcohols to control the rheology of the inks. The inks can be formulated into pastes with non-Newtonian rheology and good screen printing properties. The inks can have low metal contamination such that they are suitable for forming semiconductor structures. The silicon based nanoparticles can be elemental silicon particles with or without dopant.
