Patent CA-2001805-A1 (CA)
Title: Method and apparatus for sputter coating stepped wafers
Inventor: HURWITT STEVEN D
IPC: C23C14/34
Filed: 1989-10-30
Abstract: A magnetron sputtering method and apparatus employing a one-piece annular target having a concave continuously smooth surface with an inwardly facing portion close to and surrounding the outer edge of a stepped wafer provides a sputtering surface with areas facing the differently facing surfaces of the wafer steps. Two concentric erosion zones on the target surface are independently energized at different electrical parameter values by synchronizing the power applied to the single target with switched activation of plasmas overlying the respective target regions which define the erosion zones. The electrical parameters and the geometry are established so as to uniformly coat the differently facing surfaces of the stepped wafer. During part of the duty cycle during which each target region is energized, parameters amy be measured. Such parameters may be those which vary with changes in geometry as for example may be due to target erosion. The operation of different target regions, such as the duty cycles or power levels for such regions, may be separately varied in response to the measurements or otherwise, to maintain uniform substrate coating as the target erodes. The target is thicker under the outer region and has an annular pole piece embedded to reduce the space separating the target erosion regions, and includes means to cool the target and reinforce it against thermal expansion.

Filed: 1989-12-29
Abstract: The field of the invention is that of multiprocessor systems of the type comprising at least one processing module consisting of processors connected to a main bus, or of several processing modules communicating with one another through bus controllers. The aim is to furnish a bus deblocking system using a completely controlled process permitting gradual and repetitive deblocking of a multibus system experiencing general blocking. According to the invention, the method consists in conferring upon a specific deblocking card a function for detecting blockage of the module and a function for freeing the bus of the said module, the said function for freeing the bus consisting in emitting a single unblocking signal (45) causing, for all the processors of the module, on the one hand a disabling of the bus allocation system (34, 35) (operating by arbitration of simultaneous access requests (30)), and on the other hand a cancellation-setting of the bus control signal (37, 38). <IMAGE>
