20100282164 | METHODS AND SYSTEMS FOR CONTROLLING TEMPERATURE DURING MICROFEATURE WORKPIECE PROCESSING, E.G., CVD DEPOSITION - 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. | 11-11-2010 |
20110163416 | METHODS FOR FORMING SMALL-SCALE CAPACITOR STRUCTURES - The present disclosure provides small scale capacitors (e.g., DRAM capacitors) and methods of forming such capacitors. One exemplary implementation provides a method of fabricating a capacitor that includes sequentially forming a first electrode, a dielectric layer, and a second electrode. At least one of the electrodes may be formed by a) reacting two precursors to deposit a first conductive layer at a first deposition rate, and b) depositing a second conductive layer at a second, lower deposition rate by depositing a precursor layer of one precursor at least one monolayer thick and exposing that precursor layer to another precursor to form a nanolayer reaction product. The second conductive layer may be in contact with the dielectric layer and have a thickness of no greater than about 50 Å. | 07-07-2011 |
