摘要:
Hardmasks and fabrication methods are presented for producing ferroelectric capacitors in a semiconductor device, wherein a hardmask comprising aluminum oxide or strontium tantalum oxide is formed above an upper capacitor electrode material, and capacitor electrode and ferroelectric layers are etched to define a ferroelectric capacitor stack.
摘要:
An apparatus and method for evaluating semiconductor structures and devices are provided. A method for evaluating at least one selected electrical property of a semiconductor device (201) in relation to a selected geometric dimension of the semiconductor device (201). The method further includes forming a plurality of semiconductor devices (201) on a substrate (202), the devices (201) having at least one geometric dimension, measuring the at least one electrical property of at least one of the semiconductor devices (201) using a scanning probe microscopy based technique, and determining a relationship between the measured electrical property and the selected geometric dimension of the semiconductor device (201). The method further includes evaluating at least one semiconductor fabrication process based upon the determined relationship.
