Methods of operating surface reactors, and such reactors, particularly spinning disc reactors require that a first reactant is fed to the reactor surface and forms a thin film on the surface. A second reactant is fed to the surface in the form of a second thin film to interact with the first film so as to overcome the impedance to interaction between the two films imposed by the existence of molecular clusters in the films. Thus, each film is fed into the receiving film at a rate such as to break up the molecular clusters in the film and thereby permit the molecules to aggressively and completely interact with one another. In the spinning disc apparatus the films are fed at respective distances from the spin axis. The interaction takes place in a thin chamber (less than 1 mm) between a retaining surface coextensive with the reactor surface whose distance from one another can be varied continuously, with the components being sheared between the surfaces to break up the molecular clusters to facilitate molecular, forced interdiffusion. Preferably each film is fed into the reaction chamber through a respective annular nozzle producing an improved uniformity of initial and continuous contacting of the reactants followed by an increase in forced interdiffusion of reactant molecules.

A method of semiconductor manufacturing is disclosed in which doping is accomplished by the implantation of ion beams formed from ionized molecules, and more particularly to a method in which molecular and cluster dopant ions are implanted into a substrate with and without a co-implant of non-dopant cluster ion, such as a carbon cluster ion, wherein the dopant ion is implanted into the amorphous layer created by the co-implant in order to reduce defects in the crystalline structure, thus reducing the leakage current and improving performance of the semiconductor junctions.

The molecular cluster ions have the chemical form A_nH_x⁺ or A_nR_zH_x⁺, where A designates the dopant or the carbon atoms, n and x are integers with n greater than or equal to 4, and x greater than or equal to 0, and R is a molecule which contains atoms which, when implanted, are not injurious to the implantation process (for example, Si, Ge, F, H or C). These ions are produced from chemical compounds of the form A_bL_zH_m, where the chemical formula of L_z contains R, and b may be a different integer from n and m may be an integer different from x and z is an integer greater than or equal to zero.
