The service lifetime of an ion source is enhanced or prolonged by the source having provisions for in-situ etch cleaning of the ion source and of an extraction electrode, using reactive halogen gases (F or Cl), and by having features that extend the service duration between cleanings. The latter include accurate vapor flow control, accurate focusing of the ion beam optics, and thermal control of the extraction electrode that prevents formation of deposits or prevents electrode destruction. An apparatus comprised of an ion source for generating dopant ions for semiconductor wafer processing is coupled to a remote plasma source which delivers F or Cl ions to the first ion source for the purpose of cleaning deposits in the first ion source and the extraction electrode. These methods and apparatus enable long equipment uptime when running condensable feed gases such as sublimated vapor sources, and are particularly applicable for use with so-called cold ion sources. Methods and apparatus are described which enable long equipment uptime when decaborane and octadecarborane are used as feed materials, as well as when vaporized elemental arsenic and phosphorus are used, and which serve to enhance beam stability during ion implantation.

Described herein are systems and methods for the generation of electric current and/or electric potential utilizing micro- or nano-channels and capillary flow, including fluidic or microfluidic batteries and electrochemical cells. The provided systems and methods use capillary force to promote fluid flow through micro- and nano-fluidic channels by evaporating fluid at one terminus of the channel, and the resulting fluid flow generates electric potential and or current. Advantageously, the described systems and methods remove the need for pressurized vessels or external pumps, increasing net energy generation and decreasing complexity and size of potential fluidic batteries.

Disclosed are an adhesive film for an organic electronic device and an encapsulant including the same, wherein the adhesive film can function to remove or block defect causes such as moisture and impurities so that the defect causes do not approach the organic electronic device, and also to minimize problems due to separation of the organic electronic device and the film and/or interfacial film delamination upon moisture removal.

A bipolar overvoltage battery pulser and method are provided that apply a positive pulse voltage and a negative pulse voltage alternately across the terminals of a battery. The object of the bipolar overvoltage battery pulser and method is to increase the cycle lifetime and capacity of storage batteries, such as lead acid batteries. The rise times for the leading edges of the positive pulses and for the trailing edges of the negative pulses are short compared to the ionic relaxation time in the electrochemical solution. Alternating between the positive and negative pulses gives each new pulse an equal starting condition without realizing any memory effect that otherwise may result if the last applied pulse was of the same polarity, which reduces the extent of overvoltage that may be applied to the battery and decrease the highest useable pulse cycling frequencies that could be achieved without experiencing pulse overlapping. The shape, type and timing of the pulses may be adjusted to create overvoltage pulses having high duration and amplitude.

The invention features in-situ cleaning process for an ion source and associated extraction electrodes and similar components of the ion-beam producing system, which chemically removes carbon deposits, increasing service lifetime and performance, without the need to disassemble the system. In particular, an aspect of the invention is directed to an activating, catalytic, or reaction promoting species added to the reactive species to effectively convert the non-volatile molecular residue into a volatile species which can be removed by conventional means.

Disclosed is a novel physiologically active protein, which is a human granulocyte colony stimulating factor isoform, constructed in order to increase the in vivo lifetime of human granulocyte colony sedtimulating factor. The human granulocyte colony stimulating factor isoform comprises a polypeptide and polyethylene glycol (PEG) bound thereto as a non-protein polymer. A specific site of the polypeptide is selected so that polyethylene can be bound to the site while not adversely affecting the activity of the protein. The amino acid of the site is modified with cysteine and polyethylene glycol is bound to the modified site. A pharmaceutical composition comprising the isoforms, genes encoding the isoforms, and a primer for modifying the amino acid sequence are also disclosed.

The present invention relates to a method for selectively etching a silicon oxide film in a semiconductor manufacturing process and comprises: a step of introducing a substrate having a silicon nitride film and a silicon oxide film to a substrate support part inside a reactor; a step of heating the substrate introduced into the reactor, so as to maintain a first temperature; a first step of supplying halogen gas and basic gas to the inside of the reactor, while the first temperature is maintained, so as to be reacted with the silicon oxide film formed on the substrate, thereby forming a reaction product on the substrate; a second step of heating the substrate, having the reaction product, up to a second temperature so as to remove the reaction product; a third step of cooling the temperature of the substrate down to the first temperature; and a step of repetitively performing the first step to the third step a preset number of times.

A ceramic lamp holder for connecting a bulb and communicating with a filament of the bulb includes a cylinder and a conductive terminal. The cylinder is made of ceramic material with its one side formed into a closed end. The closed end is provided with a through hole for allowing one end of the filament to pass through. The outer surface of the cylinder is formed with an outer thread and a trough recessed into the surface of the outer thread. The conductive terminal is fixedly received in the trough to be partially exposed to the surface of the outer thread. One end of the conductive terminal is connected to the other end of the filament. Via the above arrangement, the wear caused by the friction between the conductive terminal and the lamp socket can be reduced, and the contact effect and the life time of the lamp holder can be increased.
