  Electron emission from the boundary is ubiquitous in capacitively coupled
plasma (CCP) and precipitates nonnegligible influences on the discharge
properties. Here we present the PIC-MCC simulation of an Ohmic-dominant heating
mode of capacitively coupled plasma where the stochastic heating vanishes and
only Ohmic heating sustains the discharge, due to sheath inversion by boundary
electron emission. The inverted CCP features negative sheath potential without
Bohm presheath, hence excluding plasma heating due to sheath edge oscillation.
The particle and energy transport of the proposed heating mode is analyzed. The
influences of boundary electron emission flux, source voltage, and neutral
pressure on the transition between classic and Ohmic-dominant CCP heating modes
are shown with designated simulation scans. A modified inverse sheath-plasma
coupling due to excessive ionization is discovered. In the end, key indicators
of the proposed heating mode in plasma diagnostics are provided for future
experimental verifications.
