Patent number: 8518184Abstract: The present disclosure provides methods and systems for controlling temperature. The method has particular utility in connection with controlling temperature in a deposition process, e.g., in depositing a heat-reflective material via CVD. One exemplary embodiment provides a method that involves monitoring a first temperature outside the deposition chamber and a second temperature inside the deposition chamber. An internal temperature in the deposition chamber can be increased in accordance with a ramp profile by (a) comparing a control temperature to a target temperature, and (b) selectively delivering heat to the deposition chamber in response to a result of the comparison. The target temperature may be determined in accordance with the ramp profile, but the control temperature in one implementation alternates between the first temperature and the second temperature.Type: GrantFiled: July 20, 2010Date of Patent: August 27, 2013Assignee: Micron Technology, Inc.Inventors: Kevin L. Beaman, Trung T. Doan, Lyle D. Breiner, Ronald A. Weimer, Er-Xuan Ping, David J. Kubista, Cem Basceri, Lingyi A. Zheng

Patent number: 7440255Abstract: A capacitor construction includes a first electrode and a layer between the first electrode and a surface supporting the capacitor construction. The capacitor construction can exhibit a lower RC time constant compared to an otherwise identical capacitor construction lacking the layer. Alternatively, or additionally, the first electrode may contain Si and the layer may limit the Si from contributing to formation of metal silicide material between the first electrode and the supporting surface. The layer may be a nitride layer and may be conductive or insulative. When conductive, the layer may exhibit a first conductivity greater than a second conductivity of the first electrode. The capacitor construction may be used in memory devices.Type: GrantFiled: July 21, 2003Date of Patent: October 21, 2008Assignee: Micron Technology, Inc.Inventors: Brent A. McClure, Casey R.

Patent number: 7321148Abstract: The invention encompasses a method of forming a rugged silicon-containing surface. A layer comprising amorphous silicon is provided within a reaction chamber at a first temperature. The temperature is increased to a second temperature at least 40° C. higher than the first temperature while flowing at least one hydrogen isotope into the chamber. After the temperature reaches the second temperature, the layer is seeded with seed crystals. The seeded layer is then annealed to form a rugged silicon-containing surface. The rugged silicon-containing surface can be incorporated into a capacitor construction. The capacitor construction can be incorporated into a DRAM cell, and the DRAM cell can be utilized in an electronic system.Type: GrantFiled: August 6, 2004Date of Patent: January 22, 2008Assignee: Micron Technology, Inc.Inventors: Guy T.

Patent number: 7279398Abstract: The present disclosure provides methods and apparatus useful in depositing materials on batches of microfeature workpieces. One implementation provides a method in which a quantity of a first precursor gas is introduced to an enclosure at a first enclosure pressure. The pressure within the enclosure is reduced to a second enclosure pressure while introducing a purge gas at a first flow rate. The second enclosure pressure may approach or be equal to a steady-state base pressure of the processing system at the first flow rate. After reducing the pressure, the purge gas flow may be increased to a second flow rate and the enclosure pressure may be increased to a third enclosure pressure. Thereafter, a flow of a second precursor gas may be introduced with a pressure within the enclosure at a fourth enclosure pressure; the third enclosure pressure is desirably within about 10 percent of the fourth enclosure pressure.Type: GrantFiled: January 6, 2006Date of Patent: October 9, 2007Assignee: Micron Technology, Inc.Inventors: Cem Basceri, Trung T.
