Multivariate method for the monitoring of etch chamber insitu cleaning Abstract: In plasma etching, the etch byproduct deposition on the chamber wall plays an influential role in controlling the density of reactive species. , particles, etc). The HF Vapor platform delivers the OEM Group patented HF Vapor process. Therefore there are much more collisions and thus the particles are heading into various directions. One advantage of this system is that fairly safe gases can be fed into the chamber, which in a plasma state become dissociated into highly reactive. Si etch rates > 3 pdmin with etch selectivities to resist > 75:l were obtained. This will ultimately result in lower product yield. Tactras™ SCCM™ etch chamber equips RF power supply on its upper and lower electrode separately. Signal of RF and its harmonics would be useful information to diagnose the state of etch process chamber condition. Compounds of fluorine, chlorine and bromine are typically used as the primary etch gases, depending on the material to be structured. Planar ICP uses an inductive coil that is placed above a dielectric window, and gases are introduced from the side of the chamber to create a plasma.

Recipe 2: Run an O2 descum for 30-45sec @ 150W. “Dry” (plasma) etching is used for circuit-defining steps, while “wet” etching (using chemical baths) is used mainly to clean wafers. The Cobra process chamber walls are fitted with an electrical heating kit, allowing for warming to approximately 80 C. For example, if an upstream step is center-fast, the etch chamber can be tuned to be edge-fast as a compensation technique. The etching chamber was evacuated using a turbomolecular pump and a rotary pump. The U-8250 dielectric system is used in a wide range of processes. The de voltage between the electrodes is measured to be 100 V when plasma is established. During the process, the plasma generates volatile etch products at room temperature from the chemical. Normally, for good uniformity, the 15cm etch source can be used for wafers up to 4”, while the 30cm etch source is suitable for wafers up to 8”.
