| 20100221583 | HDD PATTERN IMPLANT SYSTEM - Methods and apparatus for forming substrates having magnetically patterned surfaces is provided. A magnetic layer comprising one or more materials having magnetic properties is formed on a substrate. The magnetic layer is subjected to a patterning process in which selected portions of the surface of the magnetic layer are altered such that the altered portions have different magnetic properties from the non-altered portions without changing the topography of the substrate. A protective layer and a lubricant layer are deposited over the patterned magnetic layer. The patterning is accomplished through a number of processes that expose substrates to energy of varying forms. Apparatus and methods disclosed herein enable processing of two major surfaces of a substrate simultaneously, or sequentially by flipping. In some embodiments, magnetic properties of the substrate surface may be uniformly altered by plasma exposure and then selectively restored by exposure to patterned energy. | 09-02-2010 |
| 20100265988 | SUBSTRATE COOL DOWN CONTROL - Methods and apparatus for precise substrate cool down control are provided. Apparatus for measuring temperature of substrates may include a cool down plate to support a substrate; a sensor to provide data corresponding to a temperature of the substrate when disposed on the cool down plate; and a computer coupled to the sensor to determine the temperature of the substrate from the sensor data. A method for measuring the temperature of a substrate may include providing a substrate to be cooled to a chamber having a cool down plate disposed therein, a sensor to provide data corresponding to a temperature of the substrate, and a computer coupled to the sensor; sensing a first temperature of the substrate after a predetermined first time interval has elapsed; comparing the first temperature to a predetermined temperature; and determining whether the first temperature is greater than, equal to, or less than the predetermined temperature. | 10-21-2010 |
| 20110061812 | Apparatus and Methods for Cyclical Oxidation and Etching - Apparatus and methods for the manufacture of semiconductor devices suitable for narrow pitch applications and methods of fabrication thereof are described herein. Disclosed are various single chambers configured to form and/or shape a material layer by oxidizing a surface of a material layer to form an oxide layer; removing at least some of the oxide layer by an etching process; and cyclically repeating the oxidizing and removing processes until the material layer is formed to a desired shape. In some embodiments, the material layer may be a floating gate of a semiconductor device. | 03-17-2011 |
