Method and appts. for ionized sputtering of materials

An ionized physical vapor deposition apparatus (10, 10a, 10b) is provided with an RF element, preferably a helical coil (30), that surrounds space (11) within a vacuum chamber (12) between a target (16) and a substrate holder (14). RF energy, preferably at about 2 MHz or elsewhere in the 0.1 to 60 MHz range, is coupled into the space to form a secondary plasma (29) in a volume (26) of the space between the substrate holder and the main plasma that is adjacent the target. The secondary plasma ionizes sputtered material which is then attracted toward a substrate (15) on the support by a bias on the substrate and/or by an axial magnetic field to impart directionality to the moving ionized sputtered particles to render them perpendicular to the substrate at incidence, so as to coat the bottoms of narrow high aspect ratio features on the substrate. A window (60) of dielectric material such as quartz, either in the wall of the chamber or inside the chamber, or insulation on the coil, protects the coil from adverse interaction with plasma. Shields (100, 200, 300) between the space and the dielectric material prevent sputtered particles coating the dielectric material. The shields are partitioned or slotted to prevent induced currents in the shields. The shields may be biased to control contamination and may be commonly or individually biased to optimize the uniformity of coating on the substrate and the directionality of the flux of ionized material at the substrate. The shield may be formed of a plurality of angled segments (302) that are spaced to facilitate communication of a secondary RF plasma from adjacent the window to the volume of the chamber where the sputtered material is ionized, with the sections angled and spaced to shadow at least most of the target from the window. Alternatively, electrically conductive shield (100) may be provided in close proximity to the window or insulation.

The invention relates to a lithium ion battery electrode cyclic attenuation mechanism evaluating method. With the method adopted, the technical problem that the various failure mechanisms of an integrated battery system are difficult to completely separate can be solved. According to the lithium ion battery electrode cyclic attenuation mechanism evaluating method, anode polar sheets, cathode polarsheets and electrolyte are assembled, so that a plurality of sets of single-layer soft-package integrated batteries can be formed; after formation is performed, empty electricity and full electricitytesting is performed; the anode polar sheets and the cathode polar sheets are taken out, and residual electrolyte is removed; and the anode polar sheets and the cathode polar sheets are assembled into soft-package laminated symmetrical batteries, and the attenuation mechanisms of the symmetrical batteries are cyclically tested and analyzed. A symmetrical battery system is adopted, the failure mechanisms of the anodes or and cathodes are separately studied, the generation of the side reactions of the anodes or cathodes is avoided, a test voltage range is narrow, and electrolyte oxidation is avoided. Compared with a half-battery system, the symmetrical battery system is limited in lithium transmission, and has no extra lithium (lithium sheet) participating in side reactions; compared with abutton-type symmetrical battery system, the soft-package symmetrical battery system ensures the sealing of a whole device and enables long-term cyclic testing.

Input buffering and queue status-based output control for a digital traffic switch

A digital traffic switch having DIBOC buffer control has a queue status-based control strategy to limit status traffic on the switch and status buffer requirements. Status messages are transmitted from inputs to outputs when the content status of a logical output queue has changed from “empty” to “not empty”, or vice versa, rather than on a “per cell” request basis. Status messages are transmitted from outputs to inputs when the clearance status of a logical output queue has changed from “not clear to release” to “clear to release”, or vice versa, rather than on a “per cell” grant basis. The status of each logical output queue is monitored at outputs by retaining and updating a single status bit which has a particular binary value when the logical output queue's status is “empty” and the opposite binary value when the logical output queue's status is “not empty”. The status of each logical output queue is monitored at inputs by retaining and updating a single status bit which has a particular binary value when the logical output queue's status is “not clear to release” and the opposite binary value when the logical output queue's status is “clear to release”. Outputs generate (but do not transmit) release grants in a logical order determined by running a grant generation algorithm. Inputs release discrete information units in a logical order determined by running a release algorithm. Status messages for logical output queues are re-transmitted when extra bandwidth is available to remove any inaccurate view of the status of the logical output queues resulting from transmission failures of the original status messages.
