Abstract
Abstract This invention relates to a new manner of carrying out chemical reactions by injection of selected forms of energy into the reaction zone by novel means. By applying this principal, many new processes result with application in a large number of different industries. The new process is generally capable of operation at room temperatures, which has advantages in the creation of certain sensitive products including uniformly doped semi-conductors, new catalysts, pure gases, high purity materials of any kind, controlled coatings, new polymers, combustion enhancement, difficult separation, petroleum refinery operations, and carrying out any reaction in which the injection of specific energy types is helpful.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
201 words
A method for producing ultra-pure coatings of metal, non-metal, organics, inorganics and other substances, which comprises passing a flow of a reagent gas of helium, or argon, through two annular electrodes across which a voltage of 200 to 300 volts is applied and bringing said reagent gas into contact with a sample gas selected from the group of W(CO) 6 , Ni (CO) 6 , silanes, perfluorobutane, whereby the reagent gas being metastable transfers its excess energy to the sample gas to produce the metal, non-metal, or other molecule in neutral high energy state, setting a laser pumped pulse tunable dye laser to the wavelength corresponding to the exact energy necessary to cause ionization of the sample gas given the energy of its high neutral high energy state, said foregoing procedure taking place in a container cavity such that an electric or magnetic field is applied so as to couple a uniform film of the particular ions involved to the site of their deposition whereby at least one layer of the selected product substance is deposited in controlled thickness on a selected target substrate, the deposit amount being controlled by controlling the rate at which the sample gas ions are formed.
Claim 2
Independent Claim
