Overview
The Applied Materials Centura DPS II and Lam Research 2300 Versys are two of the most prominent tools in the used semiconductor equipment market, each serving distinct but critical roles in wafer fabrication. The Centura DPS II is a plasma-enhanced chemical vapor deposition (PECVD) system designed for depositing high-quality dielectric films, such as silicon dioxide and silicon nitride, on 300mm wafers. It is part of Applied Materials' Centura platform, known for its flexibility in deposition processes. Key features include a vertical single-wafer chamber, advanced gas distribution systems, and compatibility with high-throughput manufacturing. It is widely used in foundries, memory manufacturing, and logic device production for interlayer dielectrics and passivation layers.
The Lam Research 2300 Versys is a high-precision plasma etch tool optimized for critical etch steps in advanced semiconductor processes. It is part of Lam’s 2300 Series platform, which dominates the etch market. The Versys model excels in etching a wide range of materials, including silicon, oxides, nitrides, and low-k dielectrics, with sub-nanometer precision. It employs advanced plasma uniformity control, real-time endpoint detection, and modular chamber designs. It is commonly deployed in logic, FinFET, and advanced packaging applications where high aspect ratio etching and profile control are required.
Specifications Comparison

Used Market Pricing
On the secondary market, AMAT Centura DPS II systems typically range from $180,000 to $320,000, depending on configuration (e.g., presence of high-density plasma modules, gas delivery upgrades) and maintenance history. Systems with post-2010 manufacture dates and verified process validation data command higher prices (~$280k–$320k).
The Lam 2300 Versys has a slightly higher price range, averaging $200,000 to $350,000, due to its role in advanced etch processes. Units equipped with Lam’s Sym3™ or Litho-Friendly Etch™ modules for sub-10nm nodes often exceed $300k. Systems from the 2300 Versys 300i or 2300 Versys 300i Plus variants are particularly sought after for their modular scalability.
Prices for both tools fluctuate based on regional demand, availability of spare parts (e.g., matching networks, showerheads), and the presence of original manufacturer (OEM) service contracts.
When to Choose Each
-
Choose AMAT Centura DPS II if your process requires dielectric deposition for interlayer or passivation layers. It is ideal for foundries, memory manufacturers, and legacy node logic production (e.g., 28nm and above). Its robustness in PECVD makes it a cost-effective choice for high-volume deposition tasks, especially where integration with existing Applied Materials tools is a priority.
-
Choose Lam 2300 Versys for advanced etch applications in logic, FinFET, or 3D NAND processes. It is essential for critical steps like gate etch, contact/via etch, and low-k dielectric etch in sub-20nm nodes. Facilities targeting high-aspect-ratio etching with tight profile control (e.g., TSVs in packaging) will benefit from the Versys’ precision and modular upgrades.
Secondary Market Availability
The Centura DPS II is more widely available on the secondary market due to its prevalence in mid-node manufacturing. It is commonly sourced from decommissioned 200mm/300mm foundries, particularly in Asia. However, newer DPS II variants with Ultra-Low-K (ULK) deposition capabilities are rarer and more expensive.
The Lam 2300 Versys is less common but highly desirable in the used market, especially in regions with advanced packaging hubs (e.g., Taiwan, South Korea). Units from the 2300 Versys 300i Plus series, designed for 7nm and below, are often acquired by emerging semiconductor startups or R&D labs. Sourcing requires careful verification of process module compatibility and spare parts inventory, as Lam’s proprietary components (e.g., Sym3™ modules) may be scarce.
Verdict
For deposition-centric workflows in mid-node manufacturing, the Applied Materials Centura DPS II is the superior choice, offering reliable performance, competitive pricing, and broad material compatibility. Conversely, the Lam Research 2300 Versys is indispensable for advanced etch processes in leading-edge logic and packaging applications, justifying its higher cost with unmatched precision and modularity. Buyers should align their selection with specific process requirements: DPS II for PECVD dielectric deposition and Versys for high-precision plasma etching. On the secondary market, prioritize systems with verified maintenance records, OEM support, and process-specific upgrades to maximize ROI.
