Title: Field effect transistor
Inventor: ASHLEY TIMOTHY
IPC: H01L29/205
Filed: 1998-06-10
Abstract: A field effect transistor (FET) is of the type which employs base biasing to depress the intrinsic contribution to conduction and reduce leakage current. It incorporates four successive layers (102 to 108): a p<SP>+</SP> InSb base layer (102), a p<SP>+</SP> InAlSb barrier layer (104), a   x   intrinsic layer (106) and an insulating SiO<SB>2</SB> layer (108); p<SP>+</SP> source and drain regions (110, 112) are implanted in the intrinsic layer (106). The FET is an enhancement mode MISFET (100) in which biasing establishes the FET channel in the intrinsic layer (106). The insulating layer (108) has a substantially flat surface supporting a gate contact (116). This avoids or reduces departures from channel straightness caused by intrusion of a gate groove, and enables a high value of current gain cut-off frequency to be obtained. In FETs with layers that are not flat, departures from channel straightness should not be more than 50 nm in extent, preferably less than 5 nm.

Title: Etching using an ink jet print head
Inventor: KAWASE TAKEO
IPC: H05B33/02
Filed: 2000-10-16
Abstract: A method is provided for etching a pattern in a material by selectively depositing onto the material droplets of a substance for dissolving or reacting chemically with the material. The droplets may be deposited from a print head of the type having a nozzle from which the material may be ejected as a series of droplets, such as an ink jet print head. In a preferred application, a series of ridges 40 can be etched from an organic insulator layer overlying a photoemissive organic polymer 6. A conductive layer 42 is then deposited and the ridges 40 of organic insulator are dissolved by solvent washing to provide an array of conductive strips which can be used as a cathode for an electroluminescent display device. The print head can also be used to provide by etching a series of ridges of an organic polymer. A transparent conducting polymer is then deposited between the ridges. The ridges are then dissolved by solvent washing to provide an array of strips of the conducting polymer which can be used as an anode in a display device. In combination, both anode and cathode can be fabricated for a display device without the need for photolithography, which is particularly advantageous for the fabrication of large area display devices.

Title: Method and mixture for use in drying a semi-conductor wafer and a dryer therefor
Inventor: SASAKI YASUSHI
IPC: F26B5/00
Filed: 2001-08-22
Abstract: A mixture of lower alcohols 5, e.g. methanol, ethanol and isopropyl, whose mean molecular weight is 46 or less, is supplied to the surface of a semiconductor wafer W which has been cleansed with water. As a result of this supply, the amount of alcohol left on the semiconductor wafer, which has been dried, can be suppressed to 2ng/cm<SP>2</SP> or less (Fig. 3) and thus any deterioration of a gate oxide film formed on the semiconductor wafer is minimised. As a result, a comparatively high yield of semiconductor products can be achieved.

Title: Estimating timing offset between first and second clocks in a communication system
Inventor: SMITH JAMES DAVID
IPC: H04J3/06
Filed: 2002-10-25
Abstract: A system for determining a timing offset between a first clock and a second clock at respective first and second points in a communications network. A series of request signals is transmitted from the first point in the network A to the second point in the network B. A series of reply signals is transmitted from the second point in the network to the first point in the network. Each reply signal corresponds to a respective one of the request signals. A request signal and a corresponding reply signal having a minimum round trip delay time are indentified and a minimum single leg delay time is determined from the minimum round trip delay time. A timing offset between the clock values of the first clock and the second clock at a first instance is estimated, the estimation being based upon the minimum single leg delay time, and a transmission time and a reception time of one of the identified request signal and the corresponding reply signal, as given by the respective clocks at the transmission and reception points of the signal. A second timing offset may be calculated using values related to request/reply signals having the next-to-minimum round trip delay time. Furthermore the estimated first and second estimated timing offsets may be used to predict a third timing offset, such estimation may be performed by using the first and second timing offsets as two terms in an arithmetic (linear) progression.
