摘要:
To provide a method for fabricating a nonvolatile semiconductor memory device in which the occurrence of a trap site formed in a tunnel oxide film can be suppressed so that W/E cycle of a memory cell transistor can be improved. A tunnel oxide film formed between a floating gate 13 and a control gate is constituted by at least one CVD oxide film formed through chemical vapor-phase growth by a low pressure CVD method, and there is provided a step of heating the CVD oxide film in a nitriding atmosphere containing N2O, NO or NH3.

Split gate type transistor made by the steps of: forming a semiconductor substrate; forming a floating gate electrode over the semiconductor substrates the floating gate electrode having at least one lateral face portion; and nitrating the at least one lateral face portion to form a nitrogen-containing layer.
摘要:
A solid electrolytic capacitor includes an anode and a dielectric layer. The anode is made of niobium or a niobium alloy. The dielectric layer is made of niobium oxide formed on the niobium or the niobium alloy. The niobium oxide has a feature that a full width at half maximum of a peak of an Mz ray of characteristic X-rays of niobium is 0.98 Å or more. The characteristic X-rays are emitted when the niobium oxide is irradiated with an electron beam.
