    摘要: A chemical vapor deposition wafer boat for supporting a plurality of wafers in an evenly spaced, upright orientation perpendicular to the axis of the boat comprises a cylinder having closed ends and comprised of mutually engaging upper and lower hemicylinders. The upper hemicylinder has diffusion zones with gas flow passageways therein in the ends and zones within from 0 to 75 and within from 0 to 15 degrees from a vertical plane through the cylinder axis. The remainder of the hemicylinder wall and the ends are baffle areas without gas flow passageways. The ends and sidewall of the lower hemicylinder comprise gas diffusion zones. The gas flow passageways comprise from 0.5 to 80 percent of the surface area of the respective gas diffusion zones.

    摘要: A process and apparatus for the low pressure, cold wall, chemical vapor deposition of refractory metals, such as tungsten on a silicon wafer. The silicon wafer is introduced into a loading lock wherein the pressure is reduced to subatmospheric pressure. The silicon wafer is transferred to a deposition chamber where it is heated to an elevated temperature. A refractory metal carbonyl vapor is introduced into the deposition chamber and dissociates to deposit a refractory metal on the silicon wafer. The wafer is transferred to an unloading lock where it is allowed to cool and is then removed.

    摘要: A low pressure control system for chemical vapor deposition (CVD) apparatus, including a vacuum pressure chamber and an exhaust pump, is provided by a vacuum pump DC motor which is supplied power from a DC motor speed controller coupled to a DC control input signal from a pulsewidth modulation DC converter. The converter receives a single pulsewidth modulated pulse train having its percentage of modulation controlled in accordance with a DC to pulsewidth modulation controller which operates in accordance with the difference between a pair of DC input signals corresponding to the actual pressure inside the vacuum pressure chamber and a desired or set point pressure respectively. The vacuum pump motor speed and accordingly the exhaust pump is controlled with a high degree of precision, thereby providing improved coating uniformity of semiconductor wafers being fabricated by the CVD apparatus.

    摘要: Thermal CVD process for forming Si.sub.3 N.sub.4 -type films on substrates by reaction of gaseous NF.sub.3 with gaseous disilane at a temperature in the range of 250.degree.-500.degree. C., at pressures of 0.1-10 Torr. The mole ratio of NF.sub.3 to silane is in the range of 0.5-3.0 and the reaction zone is preferably isothermal (T controlled to within .sup.+ 5.degree. C.). The resulting films have RI's in the range of 1.4 to 3.0. The process parameters can be controlled to dope the film with H and/or F, or to create zones of differing properties within the film. The process does not cause radiation damage, metal migration, stored charge dissipation or high levels of impurities. Control of distance between adjacent wafers and wafer-to-wall spacing combined with laminar gas flow gives excellent film thickness uniformity, on the order of below about .+-.5% across the wafer face, both within (across) wafers and from wafer to wafer (batch uniformity).
