    摘要: A phase-changeable layer and a method of forming the same are disclosed. In the method, a first hydrogen gas is introduced into a reaction chamber into which a substrate is loaded at a first flow rate to form first plasma. A primary cyclic CVD process is carried out using precursors in the reaction chamber to form a lower phase-changeable layer having a first grain size on the substrate. A second hydrogen gas is introduced into the reaction chamber at a second flow rate less than the first flow rate to form second plasma. A secondary cyclic CVD process is carried out using the precursors in the reaction chamber to form an upper phase-changeable layer having a second grain size smaller than the first grain size on the substrate, thereby forming a phase-changeable layer. Thus, the phase-changeable layer may have strong adhesion strength with respect to a lower layer and good electrical characteristics.

    摘要: 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.
