    摘要: A method for the in situ cleaning of a semiconductor deposition chamber utilized for the deposition of a semiconductor material such as titanium or titanium nitride comprising, between wafers, introducing chlorine gas into the chamber at elevated temperature, purging the chamber with an inert gas and evacuating it before introduction of the next wafer. A two-stage between wafer cleaning process is carried out by introducing chlorine into the chamber at elevated temperature, thereafter initiating a plasma without removing the chlorine, purging the chamber with an inert gas and evacuating it before introduction of the next wafer. In a preferred embodiment, a thin protective film of titanium is deposited on the inner surfaces of the chamber prior to utilizing the chamber for the deposition of such material. The protective layer is replenished following each two-stage cleaning.

    摘要: A multiple step chemical vapor deposition process for depositing a tungsten silicide layer on a substrate. A first step of the deposition process includes a pretreatment step in which WF6 is introduced into a deposition chamber. Next, the introduction of WF6 is stopped and a silicon-containing gas, e.g., SiH4, is introduced into the chamber. Finally, during a third step, the SiH4 flow is stopped and DCS and WF6 are introduced into the chamber to deposit a tungsten silicide layer on the substrate.

    摘要: In one embodiment, a method for forming a metal-containing material on a substrate is provided which includes forming a metal containing barrier layer on a substrate by a plasma-enhanced cyclical vapor deposition process, exposing the substrate to a soak process, and depositing a conductive material on the substrate by a second vapor deposition process. The substrate may be exposed to a silicon-containing compound (e.g., silane) during the soak process. In some examples, a metallic nitride layer may be deposited subsequent to the soak process and prior to the second vapor deposition process. In other examples, the metal containing barrier layer contains metallic titanium, the metallic nitride layer contains titanium nitride, and the conductive material contains tungsten or copper. The plasma-enhanced cyclical vapor deposition process may further include exposing the substrate to a nitrogen precursor, such as nitrogen, hydrogen, a nitrogen/hydrogen mixture, ammonia, hydrazine, or derivatives thereof.

    摘要: In a two stroke fuel injection type internal combustion engine provided with intake and exhaust valves, a basic amount of fuel to be injected is calculated in accordance with an engine load and engine speed. Values of a factor corresponding to a ratio of air captured by an engine cylinder for combustion to the total amount of air introduced into the engine are stored in a memory in accordance with combinations of an engine load and engine speed. A value of a captured air factor corresponding to a detected combination of an engine load and speed is calculated by a map interpolation. The basic amount is corrected by the captured air factor so that a desired air-fuel ratio is obtained. The captured air factor may be further corrected in accordance with a secondary engine condition, other than an engine load and speed, such as a cooling water temperature, intake air temperature, atmospheric air temperature, atmospheric air pressure, exhaust gas temperature, or intake pressure.
