Abstract
Description
Technical Field
[0001] The invention relates to the technical field of electronic materials, and in particular to a synthesis device for a high-purity metal complex precursor. Background Art
[0002] The application of high dielectric constant materials (High-K) in ultra-large-scale integrated circuits (ULSI) is very necessary. The reason is that when the device size is reduced, the planar structure area A is reduced accordingly. In order to ensure the capacitance, high dielectric constant materials are needed. Conventional high dielectric constant materials include oxides of Hf (hafnium), Zr (zirconium), Ta (tantalum), Ti (titanium), Y (yttrium), etc., as well as new materials such as titanates doped with alkaline earth metal materials, such as barium strontium titanate (BST), barium zirconate titanate (BZT), etc. Generally, precursor materials of elements such as Hf, Zr, Ta, Ti, and Y are used to obtain the above-mentioned high dielectric constant materials by atomic layer deposition (ALD) or chemical vapor deposition (CVD). Therefore, high-quality precursor materials are the key support for achieving High-K thin film deposition.
[0003] Zirconium dioxide film has a moderate dielectric constant (K~25) and is compatible with traditional silicon-based integrated circuit processes, so it is considered to be the most promising new gate dielectric material. Atomic layer deposition (ALD) technology, as a cutting-edge nanostructure manufacturing technology, forms smooth, uniform, controllable, high-quality films through orderly, self-limiting saturated chemical reactions on the substrate surface with good repeatability, making it widely used in microelectronics science, optical films, and nanotechnology. In ALD technology, the process of obtaining oxide films first introduces a gas-phase precursor, which then reacts chemically on the wafer surface to form the desired film structure.
[0004] When preparing ZrO2 thin films using atomic layer deposition (ALD) technology, commonly used precursor sources include tetrakis(dimethylamino)zirconium, tetrakis(diethylamino)zirconium, tetrakis(methylethylamino)zirconium, cyclopentadienyltris(dimethylamino)zirconium, etc. These high-purity precursor sources are expensive and most of them need to be imported from abroad. In addition, when using tetrakis(dimethylamino)zirconium, tetrakis(diethylamino)zirconium, and tetrakis(methylethylamino)zirconium as precursors to deposit zirconium oxide films, although the film growth rate reaches 0.1nm / cycle, this rate still cannot fully meet the demand. Therefore, the development of a source material with a faster deposition rate, a simple synthesis process, and stable properties is extremely important for improving production efficiency and reducing costs.

Then this patent is a synthesis of metal precursor organic carbonyl cobalt compounds, but currently it is necessary to synthesize n-propylcyclopentadienyl tris(dimethylamino) zirconium, and it is necessary to synthesize n-propylcyclopentadiene first, and then synthesize n-propylcyclopentadiene zirconium trichloride, and it is best to synthesize n-propylcyclopentadienyl tris(dimethylamino) zirconium, so a device that meets this synthesis route is needed.
