Top Used Applied Materials Centura Ultima HDP Specs

To evaluate the used Applied Materials (AMAT) Centura Ultima HDP-CVD device, the key is to see whether its high-density plasma source is stable, whether the cavity configuration is 200mm or 300mm, and to keep a close eye on its gap filling (gap-fill) capability at nodes below 65nm. For renovation experts, whether the sign is loud or not is not important. The core is the specifications of the radio frequency matching network (RF match network) and electrostatic suction cup (ESC), whether it can withstand your current fluorine-containing or non-fluorine processes.

The following technical breakdown will directly give you an inventory of the hard-core parameters required for factory matching evaluation and purchase of pre-inspection machines: covering various core indicators such as physical, electrical and operational.

Quick Facts: Land Area And Factory Requirements

Whether you can use this used equipment depends largely on the carrying capacity of your factory, not the price of the equipment itself. HDP is destined to be a “power consumer” if it wants to generate high-density plasma.

Category	Specification	Notes
Electrical Load	208V AC, 3-Phase	Typical Centura platform configuration; full 4-chamber system may reach 80–120 kVA peak load during plasma operation
Peak Power Consumption	80–120 kVA (system peak surge)	Driven by high-density plasma generation and multi-chamber operation
Exhaust & Vacuum	High-flow dry pump + booster system required	Must handle corrosive by-products; scrubber capacity must support high SiH₄ and Ar gas flows
Process Gas Handling	SiH₄, Ar (high flow typical for HDP-CVD)	Requires corrosion-resistant exhaust and abatement system
Maintenance Clearance	Minimum 1.2 meters around mainframe	Required for chamber service, handling, and swing-radius access
Facility Requirement	High-capacity utility hook-up	Utility infrastructure is often the limiting factor vs. tool purchase cost
System Constraint	High-power plasma process tool	Electrical and exhaust infrastructure readiness determines deployment feasibility

Power supply load:

Centura platforms usually consume 208V AC, three-phase. If a fully equipped 4-chamber Ultima HDP is running, peak power will often soar to between 80kVA and 120kVA.

Exhaust and vacuum:

The process gas flow rate is large and must be equipped with a corrosion-resistant dry pump/Roots pump combination. Be sure to make sure that the exhaust gas treatment system (Scrubber) in your factory can swallow the large flow of silane (SiH4) and argon (Ar) like the HDP process.

Maintenance space:

In addition to the area occupied by the equipment itself, at least 1.2 meters “wiggle room” must be left around the main unit, otherwise it will be impossible to perform maintenance without opening the cavity.

Technological Evolution: Ultima Vs. Ultima Plus (+) Cavity Comparison

For renovation evaluation, it is necessary to be able to distinguish between the standard Ultima and Ultima Plus cavities, because most of the RF components inside cannot be mixed. The two look identical on the outside, but the performance caps for doing gap-fill are very different.

Core subsystem differences:

RF generator frequency:

The standard version of Ultima is basically locked to a fixed frequency source of 2.0MHz. However, the Ultima+ version has much finer control over the bias frequency, which is too important when making advanced process logic chips. It can accurately control the ion bombardment energy and prevent the bottom of the groove from being damaged.

Back cooling specifications:

Focus on the helium cooling zone (He cooling zones) on ESC. Older models may only have single-zone cooling, while later-produced used Ultima HDPs basically come standard with dual-zone cooling, which can make the film stress distribution throughout the wafer much more uniform.

Hardware Engineer’s Guide To Pit Avoidance: 3 Fatal Checkpoints

Buying a used Ultima HDP, if you only want to see if it can “power on and light up”, then the risk is too great. A knowledgeable surveyor must be staring intently at the three most vulnerable and extremely expensive components below:

Radio Frequency Matching Box (Match Box) Lazing:

HDP process is hot and high voltage. It must be disassembled to see if there is any trace of carbon accumulation or ignition (Arcing) in the capacitance inside the matching network. If you go through the Log log and find that “matching time (Time-to-Match)” exceeds 3 seconds, the box will most likely have to be overhauled at a high price.

Degradation of ESC ceramic layer:

If the previous owner had frequently used high-fluoride formulations (such as FSG), the ceramic coating on the electrostatic suction cup might have been obsolete long ago. Replacing it with a new ESC can even cost 15% of the residual value of this second-hand device.

Molecular Pump (Turbo Pump) Vibration Spectrum:

Never watch the pump not turn. Ask for a vibration analysis report directly. HDP byproducts accumulate on the blades extremely easily; a high vibration value means that this pump, which is tens of thousands larger, will go on strike immediately.

V-Q-C Valuation Models: Quantifying The True Value Of Used Equipment

This is my summary of a set of framework, specifically to help engineers put aside the surface of the equipment “bright”, to find out the real health of second-hand Centura platform:

V(Vacuum Excellence-Vacuum Hard Power):

This is the chassis. The vacuuming must meet the standard within the specified time, and the leak-back rate must be below 1 mTorr/min.

Q(Plasma Quality-Plasma quality):

This is the heart. The RF output fluctuation must not exceed ± 1%. As long as it is unstable here, the resulting gap-fill density is definitely high and low.

C(Consumable Availability-supplies supply):

This is the back road. Be sure to check this year’s heating base and ceramic ring, the market can not find 2 for (second-source) suppliers. If you can only be tied to death by the original high-priced contract, subsequent maintenance will be very uncomfortable.

Factory Service Docking: Power Budget And Pipeline Access Details

If you want to smoothly connect this second-hand equipment into the existing Fab factory, you have to calculate a very accurate “power budget account”. Many hardware engineers tend to omit the heat dissipated by the RF generator, which requires a considerable flow of process cooling water (PCW) to pressure it.

Category	Requirement	Notes
PCW Flow Rate	15–20 GPM	Required for cooling RF generators and chamber thermal load management
PCW Pressure	60–80 PSI	Ensures stable thermal regulation across process modules
Thermal Load Consideration	RF generator heat dissipation	Often underestimated during fab integration planning
Utility Planning	Power budget required for full tool integration	Includes RF, vacuum, cooling, and exhaust subsystems
Weight (Mainframe)	>4,500 lbs (fully loaded)	Must account for distributed load during installation
Structural Requirement	Rated raised floor / sub-fab support	Load concentration must be verified for safety compliance
Integration Risk	Cooling + power mismatch	Primary cause of post-installation instability in reused systems

PCW requirements:

The water pressure must be 60-80 PSI and the flow must be guaranteed to be 15-20 GPM (gallons per minute) to ensure that the generator and chamber operate within a safe temperature.

Load-bearing limit:

The weight of the fully equipped host can exceed 4500 pounds (about 2 tons). It is necessary to check whether your elevated floor or the steel structure of the lower factory area (Sub-fab) can withstand such a large concentrated load.

FAQs

1. Can the used 200mm Ultima HDP be upgraded to 300mm?

Basically don’t think. Although the software and some air discs are similar in length, the skeleton of the main frame, the stroke of the manipulator and the volume of the cavity are completely different things. The cost of hard change is better than buying a serious 300mm device (Centura AP).

2. If the 4 chambers are fully equipped, how much capacity (Throughput) can you run?

Take the conventional 5000 Å plated silica as an example, including the clean cavity cycle (Remote Plasma Clean), the production capacity is about 45 to 60 pieces per hour (WPH), depending on what process formula you run.

3. Can this machine be used for TSV (through silicon via) applications?

Absolutely no problem. It can fill the high aspect ratio structure that standard PECVD cannot enter, and the step coverage is extremely beautiful, so it is often used as the liner and isolation layer of TSV.

4. What are the most common gases in the system?

The conventional gas cabinet of this used equipment generally includes silane (SiH4), oxygen (O2), argon (Ar) and helium (He). In addition, nitrogen trifluoride (NF3) is used for cavity cleaning.

5. How to check the compatibility of software versions?

Check the Centura version of the operating system (the Solaris system was usually run in the early stage, and the PC platform was changed in the later stage). Focus on the software license (License) and ensure that the certificate has the exclusive “Ultima” algorithm permission for your process.
