Higgs factory detectors require unprecedented precision to fulfill their physics program. A linear collider (such as ILC, C3, and CLIC) enables this precision with low duty cycles, low backgrounds, and reach to the TeV center-of-mass energy. The SiD Collaboration Monolithic Active Pixel Sensor (MAPS) technology for tracking and electromagnetic calorimetry (ECal), will result in high granularity, thin sensors, good time resolution (<nsec), and small dead areas. Detailed simulation of ECal performance, based on the first MAPS prototype (NAPA-p1) designed by SLAC, confirms previous results, indicating electromagnetic energy resolution based on digital hit cluster counting provides improved performance over the SiD TDR analog design, with two particle separation to the millimeter scale in the ECal. Wafer-scale sensors are the long-term goal.
