A low voltage arc flash switch (4;84;134) includes a sealed housing (8) and gas insulation (10) within the sealed housing. A plurality of conductors (12) include a number of gaps (14) therebetween within the sealed housing. A triggering mechanism (15) is structured to cause a breakdown of the number of gaps.
Abstract:
Proactive arc management systems and methods are disclosed. In many implementations, proactive arc management is accomplished by executing an arc handling routine in response to an actual arc occurring in the plasma load and in response to proactive arc handling requests in a sampling interval. The number of proactive arc handling requests in a sampling interval is a function of a proactive arc management count that in turn is a function of actual number of arcs in a preceding sampling interval. Accordingly during a present sampling interval proactive arc management executes arc handling for actual arcs in the present sampling interval and for each count in a proactive arc management count updated as a function of the number of arcs in the immediately preceding sampling interval.
Abstract:
Embodiments of the present invention generally provide an inductively coupled plasma (ICP) reactor having a substrate RF bias that is capable of control of the RF phase difference between the ICP source (a first RF source) and the substrate bias (a second RF source) for plasma processing reactors used in the semiconductor industry. Control of the RF phase difference provides a powerful knob for fine process tuning. For example, control of the RF phase difference may be used to control one or more of average etch rate, etch rate uniformity, etch rate skew, critical dimension (CD) uniformity, and CD skew, CD range, self DC bias control, and chamber matching.
