In a method of forming an ohmic layer of a DRAM device, the metal silicide layer between the storage node contact plug and the lower electrode of a capacitor is formed as the ohmic layer by a first heat treatment under a first temperature and an instantaneous second heat treatment under a second temperature higher than the first temperature. Thus, the metal silicide layer has a thermo-stable crystal structure and little or no agglomeration occurs on the metal silicide layer in the high temperature process. Accordingly, the sheet resistance of the ohmic layer may not increase in spite of the subsequent high temperature process.

A system and method for depositing a film within a reaction chamber are disclosed. An exemplary system includes a temperature measurement device, such as a pyrometer, to measure an exterior wall surface of the reaction chamber. A temperature of the exterior wall surface can be controlled to mitigate cleaning or etching of an interior wall surface of the reaction chamber.

A light emitting diode (LED) bulb includes a heat sink, a circuit layer having two opposite sides, multiple LEDs mounted on one side and an electrical insulating layer connected between the opposite side and the heat sink. Heat generated by the LEDs is conducted to the heat sink through the circuit layer and the electrical insulting layer and is dissipated quickly. Further, a fan can be mounted on the fins to dissipate heat from the heat sink more quickly. Therefore, the LED bulb has good heat dissipating efficiency.

A method for producing a stretch-thinned elastic article having dimensional stability over time and at elevated temperatures in which a thermoplastic block copolymer is melt-processed into a stretchable article such as a film or fiber. The article is then conditioned at an elevated temperature greater than or equal to a glass transition temperature (Tg) of a hard phase of the thermoplastic block copolymer. The article is stretch-thinned at the elevated temperature to a desired percentage stretch, forming a stretch-thinned article, after which it is cooled to a temperature below the glass transition temperature of the hard phase of the thermoplastic block copolymer. Films produced by this method are suitable for use in durable and disposable articles including personal care articles such as diapers, incontinence wear, training pants, and feminine care articles, as well as wound dressings, wipes, towels, napkins, and protective apparel.

Provided is a substrate-processing device capable of preventing a top lid from sagging downward by the own weight of the substrate-processing device and/or a vacuum suction force generated by a vacuum pump and/or thermal shock at high temperature process, in a chamber including a plurality of reactors. Also, provided is a rotating shaft for transferring a substrate between the plurality of reactors.

An orthopedic screw with an internal bore and mating driver has a bioabsorbable polymer component. To increase the torque tolerance of the screw and to minimize the likelihood of the driver stripping inside the bore of the screw, the screw and driver are heat treated together to shrink fit the screw onto the driver thereby increasing the driver-to-screw contact and distributing the loading force over a greater area to protect against material failure. The heat treatment involves heating the screw to an elevated temperature and holding that temperature for a period to promote stress relaxation and/or crystallization of the material.

Susceptor plates are provided for high temperature (e.g., greater than 1000° C.) batch processing of silicon wafers. The susceptor plates are designed to accommodate one wafer each, and a plurality of loaded susceptor plates are vertically spaced apart in a susceptor plate holder during batch or furnace processing. The susceptor plates provide “full” support beneath the wafers, with openings of at most 20 mm in diameter in the support surface. Protrusions are also kept to a minimum. The susceptor plates thus prevent the wafers from sagging beyond the point of plastic deformation. The support surface is also ground or polished to remove protrusions beyond a prescribed height. For a given treatment temperature, the susceptor plates permit higher ramp rates without wafer plastic deformation or sticking to the susceptor plate. In one embodiment, the susceptor plates are pre-bent in a direction opposing the direction of sag.

The present invention employs hydrogels as acoustic couplings for clinical applications of ultrasound imaging and therapy, but is particularly applicable to high intensity focused ultrasound (HIFU) based therapy. While other materials can be used, it has been determined that polyacrylamide is sufficiently robust and transmissive to withstand the high temperatures encountered in HIFU therapy. One embodiment of a hydrogel coupling is configured in shape and size (length) to ensure that a focal region of an ultrasound transducer is disposed proximate the target area when the distal tip of the transducer is in contact with tissue. These couplings can be shaped to correspond to the beam focus characteristics of specific transducers. Water can be applied to hydrate the tip of the hydrogel coupling during use, and medication absorbed into the hydrogel material can be applied to the tissue in contact with the distal surface of the hydrogel.

A filled polymer composition comprises (i) an ethylene/α-olefin interpolymer, and (ii) a filler.

The present invention provides a temperature control unit for an electrostatic adsorption electrode that is capable of controlling the wafer temperature rapidly over a wide temperature range without affecting in-plane uniformity while high heat input etching is conducted with high wafer bias power applied. A refrigerant flow path provided in the electrostatic adsorption electrode serves as an evaporator. The refrigerant flow path is connected to a compressor, a condenser, and a first expansion valve to form a direct expansion type refrigeration cycle. A second expansion valve is installed between the electrostatic adsorption electrode and the compressor to adjust the flow rate of a refrigerant. This makes it possible to compress the refrigerant in the refrigerant flow path of the electrostatic adsorption electrode and adjust the wafer temperature to a high level by raising the refrigerant evaporation temperature. Further, a thin-walled cylindrical refrigerant flow path is employed so that the thin-walled cylinder is deformed only slightly by the refrigerant pressure.
