摘要:
A reaction chamber (12, 49) is adapted to be coupled to a source of microwave radiation. A pair of opposed field enhancing electrodes (18, 21; 62, 63) concentrate microwave energy so as to form plasma in a localised region between the electrodes. Gas passages are arranged for passing a gaseous medium into and out of the chamber so that the gaseous medium passes through the said localised region of plasma. The electrodes comprise electrically conducting tubes (18, 21; 62, 63) held in electrode holders (17, 19; 53, 54) located in the chamber wall, the electrode tubes being removable and replaceable from outside of the apparatus.

The invention relates to a technical solution for treating and coating non-conductive, dielectric surfaces using plasmas excited by microwaves. According to said method a) the energy required for the formation of the plasma (4) is supplied in the form of modulated microwaves, produced by a microwave generator (15), to the hollow wave-guiding structure (1), which contains the object to be treated (2) and is closed on all sides to retain the microwaves b) the plasma (4) is ignited (3) using an ignition device (11) at a predetermined point which is spatially separate from the entry point (5) of the microwaves c) the flowing localised plasma (4) moves under its own momentum in the hollow wave-guiding structure (1) from the ignition point (3) over the surfaces to be treated in the direction of the entry point of the microwaves (5), a hollow space which is sufficient to allow the passage of plasma being provided above the surface to be treated in the treatment chamber (9) d) the plasma treatment is carried out in and above the atmospheric pressure range using an atmospheric composition supplied by a device (12), which is suitable for the plasma treatment e) the flow of plasma (4) is halted by a device (13), as soon as it has coated the surface to be treated.

A free-wheeling lock assembly (10) includes a free-wheeling lock mechanism (12) which prevents damaging forces from being applied to the components of the lock assembly if the lock cylinder (20) is forcibly rotated by a key other than the proper key (14) or by some other instrument. A detent mechanism (26), which functions independent of spring bias, couples the sleeve (18) to the case (16) in the presence of the proper key (14) in the keyway. A clutch mechanism (28) couples the cylinder (20) to the driver (24), but decouples the driver (24) from the cylinder (20) for an over-torque condition. The cylinder lock assembly further includes a locking mechanism (30) which prevents operation of the latching mechanism (32) of the lock assembly if the cylinder (20) is slam-pulled from the case (16). The tumblers (22) are isolated from rotary motion of the tumbler ward.

A portable container is provided for handling an implant. The portable container comprises a sealed compartment enclosing a fluid of a pre-defined composition and at least one implant configured to be installed in a live subject. The portable container may further comprise at least one electrode made of an electrical conductive material, electrically associated with an electric conductor outside the sealed compartment and configured for applying a plasma generating electric field inside the sealed compartment. An apparatus for plasma treatment of an implant and having an activation device is further provided. The activation device comprises a slot configured to receive a portable container, and an electrical circuit configured to be electrically associated with at least one electrode. The electrical circuit is configured to provide to the at least one electrode electric power suitable for applying a plasma generating electric field in the sealed compartment, when the portable container is disposed in the slot.
摘要:
A plasma etcher device (1) and corresponding method for decapsulating (i.e. removal of encapsulation or package of) an electronic or semiconductor sample (46), by means of microwave resonance induced plasma jet (44) based etching. The plasma jet is generated in a microwave resonance cavity (6) and ejected towards the sample (46). The proposed device and method employ a liquid masking layer (58) on top of the sample (46), to confine the plasma jet (44) and improve the etching accuracy.
摘要:
A method of bevel edge processing a semiconductor in a bevel plasma processing chamber in which the semiconductor substrate is supported on a semiconductor substrate support is provided. The method comprises evacuating the bevel etcher to a pressure of 3 to 100 Torr and maintaining RF voltage under a threshold value; flowing a process gas into the bevel plasma processing chamber; energizing the process gas into a plasma at a periphery of the semiconductor substrate; and bevel processing the semiconductor substrate with the plasma.
摘要:
A method of patterning a surface of a substrate comprising: (a) applying a coating to the surface to form a coated surface, and (b) treating the coated surface with a patterned microplasma comprising a plurality of localised microplasma discharges such that localised regions of the coated surface are selectively exposed to the localised microplasma discharges to form exposed localised regions and unexposed regions that have not been substantially exposed to a microplasma discharge; wherein the coating at the exposed localised regions is modified by the patterned microplasma and the coating at the unexposed regions is substantially unmodified to form a patterned surface on the substrate.
