发明名称 METHOD FOR REDUCING RESIST POISONING DURING PATTERNING OF STRESSED NITROGEN-CONTAINING LAYERS IN A SEMICONDUCTOR DEVICE
摘要 By providing a silicon cap layer on a compressive silicon nitride layer, the diffusion of nitrogen into sensitive resist material may be efficiently reduced, while the silicon may be converted into a highly compressive silicon dioxide in a later manufacturing stage. Consequently, yield loss due to contact failures during the formation of semiconductor devices requiring differently stressed silicon nitride layers may be reduced.
