    Abstract: Techniques are provided for manufacturing phase-shifted masks. According to one technique, a facilitator provides, on behalf of a set of one or more parties that desire masks, subsidies for production of phase-shifted masks. The manufacture of the phase-shifted masks is paid using compensation that includes the subsidies from the facilitator. One or more mask makers manufacture the phase-shifted masks for the compensation. The facilitator receives, from the set of one or more parties, compensation for the subsidies based on one or more factors including a factor that reflects market success of integrated circuits produced using the phase-shifted masks. In addition to the subsidies, the facilitator may provide a variety of value-added services.
