Abstract: Doping copper interconnects (100) with silicon (115) has been shown to improve Electromigration and Via Stress Migration reliability. After copper (118) is deposited by electrochemical deposition and chemically-mechanically polished back, doping is achieved by flowing SiH4 over the copper interconnect (100) for 0.5 to 5 seconds at a temperature of 325-425° C.

Abstract: A method for fabricating a non-FLASH integrated circuit that minimizes Vmin shift. A protective overcoat (134) is deposited to protect and encapsulate the top metal interconnect layer (118). The protective overcoat (134) is patterned and etched to form bondpad windows either before or after depositing the final metal interconnect layer (136). A sinter that is normally performed after forming the bondpad windows is either omitted or the temperature of the sinter is kept at or below 350° C.

Abstract: A method for fabricating a non-FLASH integrated circuit that minimizes Vmin shift. A protective overcoat (134) is deposited to protect and encapsulate the top metal interconnect layer (118). The protective overcoat (134) comprises silicon oxynitride.

Abstract: A method for fabricating a non-FLASH integrated circuit that minimizes Vmin shift. A protective overcoat (134) is deposited to protect and encapsulate the top metal interconnect layer (118). The protective overcoat comprises silicon nitride formed using deuterium based process gases (e.g. SiD4 and ND3) instead of hydrogen-based process gases. The protective overcoat (134) is patterned and etched to form bondpad windows either before or after depositing the final metal interconnect layer (136).

Abstract: An apparatus in a chemical vapor deposition (CVD) system monitors the actual wafer/substrate temperature during the deposition process. The apparatus makes possible the production of high quality aluminum oxide films with real-time wafer/substrate control. An infrared (IR) temperature monitoring device is used to control the actual wafer temperature to the process temperature setpoint. This eliminates all atmospheric temperature probing. The need for test runs and monitor waters as well as the resources required to perform the operations is eliminated and operating cost are reduced. High quality, uniform films of aluminum oxide can be deposited on a silicon substrates with no need for additional photolithographic steps to simulate conformality that are present in a sputtered (PVD) type application. The result is a reduction in required process steps with subsequent anticipated savings in equipment, cycle time, chemicals, reduce handling, and increased yield of devices on the substrate.

Abstract: A process and apparatus for Al.sub.2 O.sub.3 CVD on silicon wafers using aluminum tri-isopropoxide in a high-volume production environment is presented. The conditions required to use ATI in a production environment and provide maximum utilization of ATI are first of all delivery of ATI via direct evaporation. The ATI source bottle is pumped out (bypassing substrates) until propene and isopropanol signals are reduced to 1% of process pressure before start of aluminum oxide deposition. Either IR spectroscopy or mass spectrometry can be used to provide a control signal to the microprocessor controller. Heating the supplied tetramer to 120.degree. C. for two hours assures complete conversion to trimer. The ATI is stored at 90.degree. C. to minimize decomposition during idle periods and allow recovery of trimer upon return to 120.degree. C. for two hours. During periods of demand, the ATI is held at 120.degree. C. to minimize decomposition.

Abstract: A removable gas injector design compatible for use in chemical vapor deposition reactors that allows proper mixing of the reactant gases, reduced cycle time associated with cleaning of gas injector components, and elimination of uncertainties associated with manual cleaning of the injector. A better reliability to the system due to the known condition of the nozzle after a clean is achieved.

Abstract: A system for monitoring and controlling the rate of growth of thin films in an atmosphere of reactant gases measures the UV absorbance of the atmosphere and calculates the partial pressure of the gases. The flow of reactant gases is controlled in response to the partial pressure.
