Title of Invention | DOPANT PASTES FOR THE PRODUCTION OF P, P+ AND N, N+REGIONS IN SEMICONDUCTRORS |
---|---|
Abstract | Dopant pastes for the selective and extensive printing of Si wafers by screen, roller, pad, stencil printing or other printing techniques customary in semiconductor technology for the production of p,p+,p++, n, n+, n++ regions in the Si wafer, containing (a)one or more components with dopant actions, (b) an SiO2 matrix which is formed by silanes of the general formula R’nSi(OR)4-n, in which R’ denotes methyl, ethyl or phenyl, R denotes methyl, ethyl, n-propyl or I-propyl, and n denotes 0, 1 or 2 (c) solvents, (d) optionally an acid and water, and (e) additives such as thickening agents ort wetting agents, the total composition having impurities in the form of metal ions in respective concentrations of less than 500 ppb, preferably less than 200 ppb (FIG. - nil) |
