    Abstract: A time-dependent substrate temperature to be applied during a plasma process is determined. The time-dependent substrate temperature at any given time is determined based on control of a sticking coefficient of a plasma constituent at the given time. A time-dependent temperature differential between an upper plasma boundary and a substrate to be applied during the plasma process is also determined. The time-dependent temperature differential at any given time is determined based on control of a flux of the plasma constituent directed toward the substrate at the given time. The time-dependent substrate temperature and time-dependent temperature differential are stored in a digital format suitable for use by a temperature control device defined and connected to direct temperature control of the upper plasma boundary and the substrate. A system is also provided for implementing upper plasma boundary and substrate temperature control during the plasma process.

    Abstract: A flexible polymer or elastomer coated RF return strap to be used in a plasma chamber to protect the RF strap from plasma generated radicals such as fluorine and oxygen radicals, and a method of processing a semiconductor substrate with reduced particle contamination in a plasma processing apparatus. The coated RF strap minimizes particle generation and exhibits lower erosion rates than an uncoated base component. Such a coated member having a flexible coating on a conductive flexible base component provides an RF ground return configured to allow movement of one or more electrodes in an adjustable gap capacitively coupled plasma reactor chamber.
