Applied Materials Endura Platform: Read the Model Right

When looking at a BOM (bill of materials), if the equipment/machine or process classification column says “Endura 5500 PVD”, do not mistake it for the material number (Part Number) of a specific component. To put it bluntly, Endura is just a series of PVD equipment platforms under Applied Materials (AMAT). It should be noted that the same platform can be equipped with completely different process cavities (Chamber), and the corresponding wafer sizes and hardware versions also vary greatly. So, just looking at the name of a platform can only help you define a large scope at most.

To fully understand the Endura platform, the trick is to take “platform”, “machine” and “specific parts record” apart. According to official information, Endura’s multi-cavity architecture can integrate pre-cleaning (pre-clean) and various metal deposition processes, and can hang up to 9 process cavities (including 2 pre-cleaning cavities). But don’t get me wrong, this is “at most” just the theoretical upper limit of platform design. It is definitely not equal to how many cavities the machine in your factory actually has installed, nor does it represent the specific cavity type. What kind of process can this device perform depends entirely on what set of cavity combinations are selected at that time.

Model number and size are key identification information

Codenames such as Endura 5500, Endura II, Endura HP, and Endura TXZ often represent products from different eras or special hardware configurations, and they should never be treated as the same hardware. Similarly, the product descriptions “6 inches, 8 inches, 150mm, 200mm” or “TXZ” are all core parameters for locking parts. When creating files or verifying materials, none of these words should be missed.

In the customer’s list, “product category” and “equipment/machine” are actually two dimensions of information: the former refers to the process or product category, and the latter refers to the equipment on which the batch of parts can be used.“ The term Endura 5500 PVD” is used very frequently, with a bunch of spare parts hanging around the cavity, such as crystal dome lift assembly, degassing/alignment module (Degas/Orienter), pressure ring (Clamp ring), base (Pedestal), anti-fouling baffle (Shield) and transmission robot (Transfer blade). However, it must be remembered that the “Endura” written in the ““Device”” column only indicates that this material number can be used on this platform, and does not mean that all versions of the platform can be used.

Part names can only provide a general classification

Bushing (Liner), antifouling plate/baffle (Shield), ring (Ring), base (Pedestal), panel (Faceplate) or gas distribution plate (Gas manifold), these words really help you quickly tell which big category a part belongs to. However, under the same English name, the material number, size, process cavity and hardware version are still varied. If specific model information is missing, never mistake similarly long nozzles, panels, air rings, or dispensing discs for the same thing.

Don’t forget that on the same platform, completely different processes such as PVD, CVD, and even Etch (etching) can be run simultaneously. Therefore, when confirming parts, it is necessary to combine the process type, specific cavity purpose, and product description. Looks like them, or has the platform’s code name in their name, which can absolutely not replace these hardcore indicators.

Correct idea for verifying parts

If you already have the original material number, the first step is to copy down the information on the part label verbatim. Not only do you need to check the material number, REV (version number), or other suffixes, but you also need to clearly see the part description and what its parent component is. Next, we need to confirm the applicable platform, host, specific process cavity, and wafer size. A special reminder here: as long as the material number contains version letters or suffixes, it must not be omitted when checking.

Many old devices often undergo cavity upgrades, platform modifications, or major changes in control systems (Retrofit). At this point, you can only identify the actual assembled hardware on the machine, the modification records, and the latest configuration files. Don’t just stare at the factory nameplate to make a judgment. In general, when a record simply says “Endura” or “Endura 5500”, that’s just a clue to give you the way; it can never replace a standard parts file that contains the complete material number, version number (Revision), and specific cavity information.
