The hydrogen flow rate is an estimated value because the calibration curve does not extend to these low flowmeter readings. However by cutting the hydrogen flow rate in half, making the flow rate near stoichiometric for the reaction, the glow is intensified around the filament substrate and will migrate along the subatrate beyond the rf electrodes. The deposit character produced by this procedure ia shown in Fig. 40. These pictures show the types of deposita that are formed at different points on the substrate. The deposition rate ig significantly affected by the flow ratio a8 shown in Table W. Table IV EFFECT OF FLOW RATIO ON DEPOSITION RATE Mole flow ratio (miWmin) 0.66 (est. ) -- _. . . -_ __ _. - -
