Embodiments of the invention provide approaches for replacement metal gate (RMG) diffusion break formation. Specifically, a diffusion break is created after source/drain (S/D) formation, thereby allowing facet free and high quality S/D formation. A dummy gate body is removed selective to a sidewall section of a capping layer and a GOx layer formed over a substrate, and the opening is then extended through the GOx layer and into the substrate by etching the dummy gate body selective to the sidewall section of the capping layer. Retaining the capping layer during the dummy gate body etch enables the diffusion break to be self-aligned to the gate and eliminates device variability due to S/D volume variations. Processing then continues with RMG poly open chemical mechanical planarization (POC) and poly open planarization (POP).

An apparatus and method for determination of change in volume of a body part or body organ on a real-time basis. In a breastfeeding application, an inflatable cuff is positioned on a nursing breast and allows direct access to the nipple by the breastfeeding infant. The inflatable cuff includes an outer shell portion and an inner inflatable bladder. The pressure in the bladder is monitored regularly by a pressure sensor, during a breastfeeding session. When the pressure drops below a preselected pressure, a controller directs a pump to pump air into the inflatable bladder to maintain the preselected pressure. The volume of added air is monitored during the breastfeeding session. Various calibrations are used to correlate the amount of added air, to the volume of breast milk withdrawn from the breast. The volume of breast milk withdrawn during breastfeeding is calculated and displayed throughout the breastfeeding session.
