Method for fabricating a semiconductor element from a dispersion of semiconductor particles

摘要

A method for forming a semiconductor element with the following steps. Depositing a suspension of particles of a semiconductor and a solution of the same or a different semiconductor or a precursor thereof on a substrate. Solidifying the mixture so that the solution electrically connects adjacent particles of the suspended particles. The semiconductors being of the same conductivity type. The soluted semiconductor comprising a solvent. The solidifying process is heating the semiconducting mixture. The soluted semiconductor is a pentacene- or a SnS2 precursor. The semiconductor particles is a collodial suspension. The deposition is by projection of liquid droplets. The process can involve a step of annealing. A semiconductor element of particles in a matrix of a binder with same conductivity type which is connecting adjacent particles. The semiconductor can be organic.
