    摘要: Methods for forming doped silane and/or semiconductor thin films, doped liquid phase silane compositions useful in such methods, and doped semiconductor thin films and structures. The composition is generally liquid at ambient temperatures and includes a Group IVA atom source and a dopant source. By irradiating a doped liquid silane during at least part of its deposition, a thin, substantially uniform doped oligomerized/polymerized silane film may be formed on a substrate. Such irradiation is believed to convert the doped silane film into a relatively high-molecular weight species with relatively high viscosity and relatively low volatility, typically by cross-linking, isomerization, oligomerization and/or polymerization. A film formed by the irradiation of doped liquid silanes can later be converted (generally by heating and annealing/recrystallization) into a doped, hydrogenated, amorphous silicon film or a doped, at least partially polycrystalline silicon film suitable for electronic devices. Thus, the present invention enables use of high throughput, low cost equipment and techniques for making doped semiconductor films of commercial quality and quantity from doped “liquid silicon.”

The method may include combining a silane compound of the formula AHaR14-a, AkHgR1′h and/or c-AmHpmR1rm with a catalyst of the formula R4xR5yMXz (or an immobilized derivative thereof) to form a poly(aryl)silane; then washing the poly(aryl)silane with an aqueous washing composition and contacting the poly(aryl)silane with an adsorbent to remove the metal M. Alternatively, the method may include halogenating a polyarylsilane and reducing the halopolysilane with a metal hydride to form the polysilane.

    摘要: Polysilanes, inks containing the same, and methods for their preparation are disclosed. The polysilane generally has the formula H—[(AHR)n(c-AmHpm−2)q]—H, where each instance of A is independently Si or Ge; R is H, —AaHa+1Ra, halogen, aryl or substituted aryl; (n+a)≧10 if q=0, q≧3 if n=0, and (n+q)≧6 if both n and q≠0; p is 1 or 2; and m is from 3 to 12. In one aspect, the method generally includes the steps of combining a silane compound of the formula AHaR14−a, the formula AkHgR1′h and/or the formula c-AmHpmR1rm with a catalyst of the formula R4xR5yMXz (or an immobilized derivative thereof) to form a poly(aryl)silane; then washing the poly(aryl)silane with an aqueous washing composition and contacting the poly(aryl)silane with an adsorbent to remove the metal M. In another aspect, the method includes the steps of halogenating a polyarylsilane to form a halopolysilane; and reducing the halopolysilane with a metal hydride to form the polysilane. The synthesis of semiconductor inks via dehydrocoupling of silanes and/or germanes allows for tuning of the ink properties (e.g., viscosity, boiling point, and surface tension) and for deposition of silicon films or islands by spincoating, inkjetting, dropcasting, etc., with or without the use of UV irradiation.
