Overview
The AMAT Endura and Novellus Speed are two prominent chemical vapor deposition (CVD) systems used in semiconductor manufacturing, but they cater to different process requirements.
The AMAT Endura, developed by Applied Materials, is a thermal CVD system primarily used for depositing tungsten (W), tungsten nitride (WN), and dielectric layers like silicon dioxide (SiO₂) and silicon nitride (Si₃N₄). It is widely employed in back-end-of-line (BEOL) processes for via and trench filling, where precise gap-fill and step coverage are critical. Key models include the Endura 5500 and Endura 7500, which support 200mm and 300mm wafers. The system features modular process chambers, low-pressure environments (typically 0.1–10 Torr), and advanced gas delivery systems for uniform deposition.
The Novellus Speed, now part of Lam Research’s portfolio, is a plasma-enhanced CVD (PECVD) system designed for high-quality dielectric film deposition. Models like the Speed 4000 and Speed 5000 are optimized for depositing conformal layers of silicon dioxide, silicon nitride, and low-k dielectrics. It uses RF plasma to enhance reaction kinetics, enabling better step coverage and film density. The Novellus Speed is commonly used in front-end-of-line (FEOL) and BEOL applications, particularly for shallow trench isolation (STI) and interlayer dielectrics (ILD).
Both tools are critical in semiconductor manufacturing but differ in deposition mechanisms, film types, and process integration.

Used Market Pricing
In the secondary market, the AMAT Endura and Novellus Speed command similar price ranges, though the Endura tends to be slightly more expensive due to its broader process versatility:
- AMAT Endura 5500/7500: $250,000 – $450,000 (depending on condition, chamber upgrades, and automation compatibility).
- Novellus Speed 4000/5000: $220,000 – $400,000 (prices vary based on plasma source age and film recipe capabilities).
Both systems are often sold with legacy automation (e.g., robotic wafer handling) or as standalone chambers. Systems with 300mm compatibility and advanced gas delivery modules (e.g., MFCs, remote plasma sources) typically fetch higher prices.
When to Choose Each
AMAT Endura
- Tungsten deposition: Ideal for filling high-aspect-ratio vias and trenches in BEOL metallization.
- Thermal CVD processes: Better suited for applications requiring minimal plasma-induced damage, such as barrier layer deposition.
- Legacy node compatibility: Commonly used in 90nm–28nm nodes, where thermal CVD remains cost-effective.
Novellus Speed
- Conformal dielectric films: Preferred for PECVD processes requiring high step coverage, such as STI and ILD.
- Low-k dielectric deposition: The plasma-enhanced process enables precise control over film porosity and density.
- Advanced nodes: More relevant in 14nm–7nm nodes where plasma-assisted deposition improves gap-fill and uniformity.
For example, a foundry producing logic chips might prioritize the Endura for tungsten via filling, while a memory manufacturer might favor the Novellus Speed for high-quality oxide deposition in DRAM isolation structures.
