Used amat endura txz: A Configuration Check Guide

When evaluating used semiconductor equipment, it is absolutely not acceptable to simply look at the machine’s condition and the platform’s name. Take Endura, the well-known multi-cavity PVD platform of Applied Materials (Applied Materials), for example. Specifically for the “TXZ” model, you have to take into account the machine’s factory year, how the cavity is equipped, the size of the wafer, and the hardware version. When inspecting a second-hand AMAT Endura TXZ, the equipment nameplate, the cavity that came with the original machine, the material number of the core parts, the extent of the renovation, and the technical drawings that were brought with the machine at the time of delivery were all explained and put into a set of acceptance standards to avoid details.

Don’t confuse platform model with TXZ specific configuration

A complete Endura machine is usually a main unit (Mainframe), wafer transfer system, loadlock (entry and exit sample chambers), process chamber, and then a bunch of vacuum and control subsystems are put together. Because various different cavities can be hung on the same platform, later systems may also be upgraded, overhauled or even replaced by the original manufacturer or customers. So, don’t mistake Endura, Endura 5500, Endura II, Endura HP, and Endura TXZ for the same thing just because the names look alike.

Before buying a machine, write down the main model, equipment serial number (SN), year of manufacture, wafer size, complete name of the cavity, hardware version number (Revision), installed components, and historical modification records. Especially when buying a used Endura TXZ, be sure to find out which specific cavity or configuration the person is talking about “TXZ” refers to, and don’t foolishly treat it as a universal model for the entire machine.

Get to the bottom of wafer size and existing modules

The Endura series of older models has been used with wafers of various sizes. Take the spare parts database data of Wuxi Zhanshuo (Chinsortech) as an example. Among the parts with TXZ edges, both 150 mm (6 inches) and 200 mm (8 inches) specifications are available. But be careful, the same size does not mean you can swap them with your eyes closed. You also have to look closely at the cavity version, interface type, core process kit (Process Kit), and its revamped status.

When talking to the seller, you must ask him to pull a solid “installation configuration sheet”. Does the quote include Loadlock, transmission mechanism, pre-cleaning module, and various process cavities? “ Second-hand Endura” is a big word that can only help you define the general scope and cannot replace the specific details on the real machine. Even if only one module is missing, or the version of a certain piece is not correct, or even a page is missing from the modification record, the cost of reinstalling the double-track and buying spare parts will take off immediately.

Always check the complete material number (PN) and identify TXZ accessories

There are countless accessories stained with TXZ, such as the cavity itself, edge ring (Edge ring), inner shield (Inner shield), isolator (Isolator), cavity insert, panel (Face plate), water tank, top cover, gas distribution plate, cavity hinge assembly, heater lifting joint and gate valve adapter plate, etc. These parts each have different air paths, water cooling, isolation and mechanical actions, and their internal structures are 180,000 miles apart. Even if they look similar, they should never be used as universal parts based on their appearance.

Whether you are looking for someone to inquire about a price or a piece, the most core iron rule is to keep a close eye on it “complete material number (PN)”, and you cannot miss any REV (version number), letters and suffixes at the end. It is best to include a part description, which one to install, which cavity to use, how large a wafer to run, how many pieces to use, and a label and multi-angle actual photos on the old part. If the label on the old part is worn off and cannot be clearly seen, just look up the material number, BOM table (bill of materials), assembly diagram, interface dimensions and historical installation records of the previous layer of components honestly, and check them against each other. Don’t leave the missing digits there “blind guess” yourself.

Determine “supply status” and “refurbishment standards” in advance

New, cleaned, repaired, refurbished or replacement? These names must be clearly written in black and white in the contract. Just because a part is cleaned does not mean that its size, surface condition, sealing and function have returned to the original factory standards. If it’s a repair part, you need to ask the other party to tell you: What problems have occurred before? Where was it fixed? What are the test results? If it is a refurbished part, you have to ask which step it was taken to remove it ——was it just washed, slightly repaired and re-coated, or was the core part inside really replaced? If it is a replacement part, then the existing target material number must be obtained, and evidence of a real hammer must be provided to prove that the difference between the two will absolutely not affect the actual process.

When quoting the entire machine, ask the seller to indicate one by one: which modules are “delivered as is (As-is)”, which have been repaired or refurbished, and which ones you have to pay for separately. If the material, coating, geometric dimensions, gas flow channels, thermodynamic or electrical properties of a component change, even if you can force it into the machine, it will definitely not be considered to meet the original factory configuration requirements.

Treat incomplete drawings and data as a hard indicator

For heavy equipment like this with multiple cavities, when purchasing a machine for inspection, the technical drawings of the main unit, transmission system, loadlock, specific process cavities, and various subsystems must be fully reviewed. These materials generally include safety manuals, installation guides, operation and maintenance manuals, parts atlases, BOM sheets, drawings, software manuals, and upgrade records. Key point: Documents from different machines should never be mixed.

Before using these drawings, clearly read the title, document number, version number, release date, as well as the platform, cavity name, wafer size, and software version to which it applies. Don’t use scanned copies with missing pages, drawings that are a mess and can’t be seen clearly, incomplete titles, or even lost version control pages as the sole standard. The operation and maintenance of subsequent machines must also be carried out by professionally trained and authorized engineers with the corresponding version of the official manual.

There must be a set of traceability acceptance standards upon receipt

Once the machine or accessories arrive, the first thing to do is to check the material number, version, quantity, supply status, batch, and packaging label to see if they are perfectly in line with what is written on the order contract. All inspection records must be matched with the specific material number, version, batch, and quantity. If it is a cleaned, repaired or refurbished part, the processing batch, date, work done and the final inspection results must also be kept in full.

When looking at the appearance, focus on dings, scratches, corrosion, residues, abnormal coating, discoloration, particulate matter, broken sealing surfaces, and areas damaged during transportation. As for interfaces, positioning surfaces, threads, air circuits, cooling water circuits, electrical connections, and sensor connectors, they must be checked one by one according to the specific purpose of these parts. Regarding the bottom line of size, vacuum level, particle number, pollution control and functional indicators, you must take the official documents of the target equipment or the acceptance specifications agreed upon by both parties in advance as the standard. Do not use data from other Endura machines or similar cavities to make a fool of yourself.

Completely align inquiry information with actual delivery scope

For example, Wuxi Zhanshuo (Chinsortech)’s business portfolio covers parts, spare parts, and components for semiconductor equipment, and some records of Endura 5500 PVD and TXZ can indeed be found in their catalog. However, it should be noted that these records are only responsible for the material numbers written in black and white, and do not mean that they are responsible for all versions of TXZ, have real-time stock, or can take on all renovation work.

Therefore, when submitting project requirements for used AMAT Endura TXZ, the most reliable method is to fully disclose the equipment nameplate, existing cavity conditions, wafer size, target material number, version, quantity, old part photos, expected supply status, acceptance requirements and delivery scope at one time. Only by verifying the configuration of the entire machine and the identity of each component one by one can you truly understand what is included and what is missing in the quotation, thereby laying a solid foundation for the subsequent installation of double-track and spare parts management.
