Clean, cost-effective, and efficient precursor delivery
Independent Channels
Each precursor has its own independent channel with fast valves, mass-flow controllers, and piping to prevent cross-contamination and piping blockages, ensuring precise dosing.
Universal Gas Manifold
The gas manifold design is versatile and can accommodate both high vapor pressure Type I and low vapor pressure Type Y precursor containers, allowing for pipeline configuration adjustments to meet different process requirements.
Rapid Response
By reducing the total gas pipeline length and minimizing residue within the pipeline during a half cycle, the system prevents residual precursors from undergoing CVD reactions. This design also enhances the pressure response rate within the reaction chamber during gas introduction.

Remote Plasma Source
For high-quality thin film applications such as passivation layers, gate dielectrics, and insulators, the A2 series offers the option to upgrade from the standard ICP (Inductively Coupled Plasma) source to the HCD (Hollow-Cathode Discharge) module, which provides higher free radical concentrations, faster film deposition, and fewer film defects. Taking the example of an Al2O3 standard film layer, the film quality achieved through this HCD technology surpasses that of the ICP method. XPS (X-ray Photoelectron Spectroscopy) analysis reveals a significant reduction in non-lattice oxygen composition. This leads to advantages such as reduced leakage current and enhanced LED efficiency. In process results for GPC (Gas Phase Cleaning), U% (Uniformity Percentage), and MSE (Material Selectivity Efficiency), the HCD module outperforms the ICP. It is evident that the HCD module can supply oxygen radicals for an 8-inch area, making it fully capable of handling the 2-inch area of the A2 series.
High-Temperature Precursor Solution
Through a high-temperature dual-valve quantitative module, the application temperature of the precursor can be raised from 200°C to 300°C and even up to 600°C, while achieving precise precursor quantification. The concept involves opening V1 to fill the space between the valves with precursor vapor, then closing V1, and subsequently opening V2 to allow all the precursor vapor within the space to flow into the reaction chamber. This method enables accurate quantification of the precursor introduced into the reaction chamber and surpasses the 200°C threshold that most brands' rapid valves cannot exceed.
With up to four precursor modules, you can easily address various film engineering requirements such as regular, super-cycles, co-dosing, etc. For example, in the development of HEMT (High Electron Mobility Transistor), you can use multiple precursors like TMAl, TMGa/TEGa, N2H4, BDEAS to stack film layers like AlN, GaN, AlGaN, SiN, and more.
