Abstract: The present invention is an RF tag having a non laminated coating for protecting the semiconductor chip, antenna, and chip antenna connections, and methods for applying the non-laminated coating.
Abstract: A method of selecting groups of radio frequency RF transponders (tags) for communication between a base station and the tags. The tags are selected into groups according to a physical attribute of the signal sent by the tags to the base station, or according to the physical response of the tags to a physical attribute of the signal sent from the base station to the tags. Communication with the tags is thereby simplified, and the time taken to communicate with the first tag is markedly reduced.

Abstract: A thin uniform film of matrix material is deposited from the gas phase on to a substrate for use in Matrix Assisted Laser Desorption and Ionization (MALDI) spectroscopy. The thin uniform film of material may be overcoated with another film of material which has a higher vapor pressure than the matrix material to prevent the matrix material from evaporating during storage and during substantial time in the vacuum environment of the mass spectrometer.
Abstract: A method for Rapid Thermal Processing (RTP) is presented, wherein the broadband reflectivity of an object is measured, and the results of the measurement used by the RTP system to adjust the RTP system parameters used in processing the object.

Abstract: A method and apparatus for optical pyrometry in a Rapid Thermal Processing (RTP) System, whereby the radiation used to heat the object to be processed in the RTP system is in part specularly reflected from specularly reflecting surfaces and is incident on the object with a particular angular distribution, and the thermal radiation from the object is measured at an angles different from the angle where the incident radiation specularly reflected from the surface of the object is a maximum.

Abstract: A method of growing a native oxide on a compound semiconductor material, comprising contacting the compound semiconductor material with an oxygen containing fluid, and pulsing a current between the compound semiconductor material the fluid, is presented. A "traveling oxide" can be produced when the oxygen containing fluid etches the native oxide. To obtain smooth oxides when the compound semiconductor material contains layers of different material, the oxide growth is monitored, and the pulse parameters changed in response to the monitoring of the oxide growth.
