A method of fabricating a ferroelectric device includes forming a ferroelectric layer on a substrate in a reaction chamber. An inactive gas is provided into the reaction chamber while unloading the substrate therefrom to thereby substantially inhibit formation of an impurity layer on the ferroelectric layer.

In a method of forming a ferroelectric capacitor, a lower electrode layer is formed on a substrate. A first crystalline layer is formed on the lower electrode layer. A ferroelectric layer is formed on the first crystalline layer. The first crystalline layer one of prevents a component of the ferroelectric layer from diffusing into the lower electrode layer and mitigates fatigue of the ferroelectric layer. An upper electrode layer is formed on the ferroelectric layer.

A probe array may be fabricated by forming probes arranged on a sacrificial substrate, forming a probe substrate above the probes, and removing the sacrificial substrate. In one embodiment, first probes may be two-dimensionally formed in row and column directions on a sacrificial substrate. Second probes may be formed between the first probes arranged in the row direction such that a distance between the first and second probes is smaller than the resolution limit in a lithography process. A probe substrate may be formed on the sacrificial substrate having the first and second probes, and the sacrificial substrate may be removed.
