摘要:
A novel lead zirconium titanate (PZT) material having unique properties and application for PZT thin film capacitors and ferroelectric capacitor structures, e.g., FeRAMs, employing such thin film material. The PZT material is scalable, being dimensionally scalable, pulse length scalable and/or E-field scalable in character, and is useful for ferroelectric capacitors over a wide range of thicknesses, e.g., from about 20 nanometers to about 150 nanometers, and a range of lateral dimensions extending to as low as 0.15 μm. Corresponding capacitor areas (i.e., lateral scaling) in a preferred embodiment are in the range of from about 104 to about 10−2 μm2. The scalable PZT material of the invention may be formed by liquid delivery MOCVD, without PZT film modification techniques such as acceptor doping or use of film modifiers (e.g., Nb, Ta, La, Sr, Ca and the like).
摘要:
Tantalum compounds of Formula I hereof are disclosed, having utility as precursors for forming tantalum-containing films such as barrier layers. The tantalum compounds of Formula I may be deposited by CVD or ALD for forming semiconductor device structures including a dielectric layer, a barrier layer on the dielectric layer, and a copper metallization on the barrier layer, wherein the barrier layer includes a Ta-containing layer and sufficient carbon so that the Ta-containing layer is amorphous. According to one embodiment, the semiconductor device structure is fabricated by depositing the Ta-containing barrier layer, via CVD or ALD, from a precursor including the tantalum compound of Formula I hereof at a temperature below about 400° C. in a reducing or inert atmosphere, e.g., a gas or plasma optionally containing a reducing agent.
