Silicon Parts
Product Overview
Semixlab supplies precision silicon components for plasma etching, deposition, thermal processing and wafer‑handling equipment. Silicon provides process compatibility with silicon wafer manufacturing while offering controllable electrical properties, thermal performance and purity for chamber‑facing consumables.
Available products include silicon focus rings, edge rings, electrodes, plates, gas‑distribution components and custom replacement parts.
Key Features & Advantages
- Semiconductor‑Grade Material: Controlled material purity helps reduce unwanted metallic contamination near the wafer.
- Tailored Electrical Properties: Conductivity type, resistivity and crystal orientation can be selected for the process requirement.
- Precision Geometry: Tight control of thickness, flatness, concentricity, hole patterns and edge profiles supports stable chamber performance.
- Controlled Surface Finish: Grinding, lapping, etching and polishing options are available for process‑facing surfaces.

Silicon Parts
Silicon parts are mainly used because they match the wafer material. That alone makes them useful, since it reduces the chance of introducing unwanted differences into the process. They are common in etching and deposition environments. Performance is generally stable, although lifetime can vary quite a bit depending on how harsh the process is.
With better machining and surface treatment, these parts have improved over time. Even so, they’re not always chosen for durability, but more for compatibility and process consistency.
