Used amat endura: A Practical Pre-Purchase Checklist

Everyone knows that when looking for used semiconductor equipment in the market, just hearing the name of the platform is useless, which is just as unreliable as buying a used car and only knowing that it is “Volkswagen”. Take Endura, the famous PVD platform of Applied Materials (Applied Materials), for example. This series spans several decades and has a wide variety of configurations. If you want to buy Used AMAT Endura, don’t just look at the shell or listen to the series name. You have to check its true identity, how the cavity is built, whether the drawings are correct, and whether the core parts are old or not. Otherwise, buying it back will be a lot of trouble.

Step 1: Check the household registration first and find out the true details of the equipment

Endura is essentially a building block-style multi-cavity platform. The base, film transfer machine (Robot), loadlock, process chamber, plus the vacuum and control system behind it, all put together to make a single device. Even if two machines look the same, the wafer size or hardware version running inside them may be completely different things.

So, when asking the seller for a price, don’t just ask “how much this one costs”, you need specific information: the main unit model, serial number, what year it was manufactured, how many inches it runs, what the names of each process cavity are, what the hardware version number (REV) is, and it is best to also include the modification record. Remember, Endura, Endura 5500, Endura II, Endura HP and TXZ, these represent different eras or specific configurations. Many of the parts and plates in them are not universal and should never be directly equated.

Step 2: Don’t make do with the cavity combination for the process

Endura platforms are primarily dry PVD metallized and often combine pre-cleaning (pre-clean) with several steps of metal deposition in a vacuum environment. Before you pay, you need to think carefully: What film should I apply? What size is needed? Should we do vacuum integration? Once you have thought it through, go to the ready-to-use configuration sheets given to the seller one by one.

When buying Used Applied Materials Endura, the seller’s platform name is at most an introduction. You need to get a detailed list that is exactly the same as the actual product. Focus on whether the loadlock, transmission mechanism, pre-cleaning module, and various process cavities are all included in the quotation. If a module is missing, or the version does not match your production line, and you want to modify it later to complete it, the amount of work will be huge.

Step 3: Keep a close eye on the core components and pay close attention to the material number and version number

When dealing with old equipment, the only reliable parts are the official bill of materials (BOM), assembly drawings and engineering change orders. Don’t be lazy when it comes to material numbers. The complete material number, REV, version letters and suffixes cannot be missed. Parts with the same name may be very different in different sizes or cavities. Do not buy them as universal parts.

Take Wuxi Zhanshuo, which manufactures semiconductor components in the industry, for example. Their product list clearly lists many parts corresponding to Endura 5500 PVD, such as ejector assembly (wafer lift assembly), pressure ring (clamp ring), cover ring (cover ring), base (pedestal), shield (shield/insulator), Robotic blade (blade assembly) and Degas cavity components, etc. However, please note that this matching only applies to the specific material numbers in their list and does not mean that the entire Endura series is usable. When inquiring about prices, be sure to search by the complete material number, and also report the platform name, cavity, wafer size, and a photo of the old part so that you can find the right part.

Step 4: TXZ-related configurations must be carefully detailed

If you come across a machine labeled Used AMAT Endura TXZ or Used Endura TXZ, don’t be fooled by the name; the TXZ in historical products represents a specific cavity technology. How to confirm? You need to look at the nameplate, cavity name, BOM sheet, and official documents.

In the customer’s material list, TXZ involves many and complicated parts: including the cavity itself (chamber body), edge ring (edge ring), inner shield (inner shield), separator (isolator), cavity insert (chamber insert), all the way to the panel (face plate), water tank (water box), top cover (lid plate), Gas track (gas manifold) and hinge (chamber hinge assembly).

Moreover, these parts often have suffixes such as 150 mm, 200 mm, or BKM, CIP, etc. Even if some parts can be hard-installed (mechanical matching), it does not mean that their vacuum, heat dissipation or process performance can meet the standards. If you encounter a poorly written record, check it honestly according to the document number and don’t make up for it yourself “it should work”.

Step 5: Don’t get bogged down in wordplay ——getting to the bottom of the spare parts’ “real condition”

The seller must clearly state the status of spare parts in the second-hand quotation. New parts, cleaning parts, repair parts, refurbished parts, replacement parts, the meanings behind these words are quite different.

“After washing ”not equal to size and seal, it will pass; if it is said to be a “repair part”, the seller must clearly explain where it is broken, what it has been replaced, and how it was measured; “refurbished part” must have specific disassembly, cleaning, coating, replacement records and final report; if it is a “replacement part”, The correspondence with the original factory material number and the verification basis must be provided.

The same applies to buying a complete machine. You must clearly state in black and white in the contract: Which modules are “delivered as is (As-is)”? Which ones have been renovated? Which ones should I buy myself later? For this old platform, we also need to confirm whether it will be repaired in the future, whether the replacement materials will be purchased, whether the software is incompatible, and the bottom line of returns, exchanges and on-site services.

Step 6: The goods received understand, the establishment of dead to the end of the acceptance criteria.

When the goods arrive, the first thing is to check the list: item number, version, quantity, supplier, batch, packaging, item by item. The inspection report must be traceable to the shipment. If it is washed, repaired or refurbished, the handling record and date must be clear.

Appearance check what? bump, scratch, corrosion, residue, off the film, particle is the foundation, focus on the vacuum sealing surface, positioning surface, thread, gas and waterway and interface are not damaged. Moving parts (such as Robot) need to measure motion trajectory, repeated positioning accuracy and interlocking signal. Vacuum parts must be tested for leakage rate and pressure holding according to equipment specifications.

Step 7: The information is incomplete, which is about equal to buying a scrap iron.

The document of the second mobile phone is a treasure. Safety specifications, installation manual, operation guide, PM manual, maintenance drawings, BOM and software instructions are indispensable. This is a multi-cavity device. The documents of the host computer are separate from those of each process cavity and Loadlock. Don’t leak them.

Before looking at the information, take a look at the platform, cavity, size and software version on the cover. The kind of scan with few pages and codes and drawings pasted into a ball cannot be used as technical basis. Finally, I would like to emphasize one point: when moving the machine, we must let the trained people operate according to the drawings of the corresponding version, and don’t fool around.

Step 8: Cooperate with spare parts and service providers

Again, back to the aforementioned Wu Xi Chinsor Technology Co., Ltd., they mainly do semiconductor parts research and development, manufacturing and after-sales, business covers PVD, CVD and ETCH equipment spare parts, mechanical parts and equipment renovation. Although they can make some parts of platforms such as Endura 5500, this does not mean that they have all the stock in their warehouse at any time, nor does it mean that they can repair any model.

Therefore, if you have a second-hand Endura bureau that needs to ask them for an inquiry, it is best to tell the whole situation at one time: the details of the equipment, the target item number, the version, how many, what color you want, and all the old photos. It is better to have drawings or samples. In addition, it is better to explain the delivery date, packaging, inspection report and acceptance criteria in advance. The more thorough the information you give, the more accurately the supplier can judge the recovery plan of this machine, and the clearer the supply boundary will be.

Summary

At the end of the day, whether a second-hand AMAT Endura is worth buying does not depend on how familiar you are with this series, but on whether its actual configuration can match your technological requirements. First, look at the main engine and cavity, then knock on the material number and version, and finally stick to the renovation scope, drawing data and acceptance conditions. Only by putting these in front can the money you spend really become the production capacity on the production line, and the installation, recovery and spare parts management in the future will not become a bad debt.
