摘要： 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.

摘要： A method and apparatus for monitoring and controlling reactant vapors prior to chemical vapor deposition (CVD). The reactant vapors are monitored at full concentration without sampling as they are transported to a CVD reactor. Contaminants detected cause a process controller to switch the transport path to direct reactant vapors to a system pump.

摘要： 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 wafers 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. The apparatus incorporates a heated source material, heated delivery lines, heated inert gas purge lines, a pressure differential mass flow controller, a control system with related valving, and a vacuum process chamber with walls that are temperature controlled as a complete source delivery system to accurately and repeatably provide source vapor for LPCVD deposition of aluminum oxide onto silicon substrates.

摘要： Methods of forming integrated circuit devices include forming a trench in a surface of semiconductor substrate and filling the trench with an electrically insulating region having a seam therein. The trench may be filled by depositing a sufficiently thick electrically insulating layer on sidewalls and a bottom of the trench. Curing ions are then implanted into the electrically insulating region at a sufficient energy and dose to reduce a degree of atomic order therein. The curing ions may be ones selected from a group consisting of nitrogen (N), phosphorus (P), boron (B), arsenic (As), carbon (C), argon (Ar), germanium (Ge), helium (He), neon (Ne) and xenon (Xe). These curing ions may be implanted at an energy of at least about 80 KeV and a dose of at least about 5×1014 ions/cm2. The electrically insulating region is then annealed at a sufficient temperature and for a sufficient duration to increase a degree of atomic order within the electrically insulating region.

摘要： A method and the device produced by the method of selective refractory metal growth/deposition on exposed silicon, but not on the field oxide is disclosed. The method includes preconditioning a wafer in a DHF dip followed by the steps of 1) selectively depositing a refractory metal on the exposed surfaces of the silicon substrate by reacting a refractory metal halide with the exposed surfaces of said silicon substrate; 2) limiting silicon substrate consumption by reacting the refractory metal halide with a silicon containing gas; and 3) further increasing the refractory metal thickness by reacting the refractory metal halide with hydrogen. Through an adequate pretreatment and selection of the parameters of 1) temperature; 2) pressure; 3) time; 4) flow and 5) flow ratio during each of the deposition steps, this invention adequately addresses the difficulties of uneven n+ versus p+ (source/drain) growth, deep consumption/encroachment by the refractory metal into silicon regions (e.g., worm holes), poor adhesion, uncontrolled selectivity and uneven morphology.
