SIASUN Vacuum Manipulator PHOENIX PLUS Series (Vacuum Manipulator PHOENIX PLUS Series)

Within vacuum process equipment—such as cluster tools for deposition, etch, or related vacuum processing—vacuum manipulators are used to transfer wafers or substrates between load locks, process modules, and metrology stations while maintaining controlled vacuum conditions.

SIASUN (Shenyang SIASUN Robot & Automation Co., Ltd.) is a Chinese robotics and automation company established in 2000, headquartered in Shenyang, with broader operations that include industrial robotics and intelligent automation solutions.

In SIASUN’s product taxonomy, the PHOENIX PLUS Series is positioned as a high-performance vacuum handling platform, emphasizing precision, repeatability, and compatibility with vacuum tool architectures. Publicly available PHOENIX PLUS materials identify multiple model variants (for example, PHOENIX PLUS-S25 and the PHOENIX PLUS-B family) and summarize performance metrics such as repeatability, maximum vacuum compatibility, and handling payload class.

Design and Features

Vacuum-optimized mechanical architecture

Vacuum manipulators differ from atmospheric robots because components must operate with minimal outgassing and particle generation while maintaining stable motion in low-pressure environments. The PHOENIX PLUS Series is described as supporting high-vacuum operation, with materials indicating compatibility to approximately 5×10⁻⁷ Pa (as listed in publicly available PHOENIX PLUS specifications).

Model family approach (multiple configurations)

Published PHOENIX PLUS documentation references:

• PHOENIX PLUS-S25, and

• PHOENIX PLUS-B variants including B31, B33, B35, B39 (as model designations), as well as mention of a PHOENIX PLUS-G variant in the same product family context.

This model-family approach is typical for vacuum transfer robotics, where end users may select different arm geometries, reach envelopes, or throughput-optimized configurations depending on tool layout and wafer size requirements.

Precision and repeatability focus

Repeatability is central for vacuum wafer handling because consistent placement reduces edge-contact risk, mitigates particle generation, and supports reliable handoff between process modules. Public PHOENIX PLUS materials list repeatability figures for representative models, including values such as ±0.06 mm for PHOENIX PLUS-S25 and ±0.05 mm for PHOENIX PLUS-B variants (as presented in the referenced specification table).

Technology and Specifications

Key published specifications (representative)

Publicly available PHOENIX PLUS Series data highlights several commonly requested industrial parameters:

• Repeatability (examples):
  PHOENIX PLUS-S25: ±0.06 mm; PHOENIX PLUS-B series: ±0.05 mm

• Payload class (example):
  PHOENIX PLUS-S25 listed at 2 kg payload

• Vacuum compatibility (example):
  Maximum vacuum listed as 5×10⁻⁷ Pa

Because vacuum transfer applications vary by tool OEM and fab requirements, additional specifications (e.g., reach, arm type, wafer size support, end-effector interface, and controller/tool communications) are commonly provided in vendor datasheets or tool-integration documents and may be finalized in project-specific configurations.

Integration considerations (tool and fab environments)

Vacuum manipulators are typically integrated into:

• cluster-tool transfer chambers,

• load lock interfaces, and

• process-module staging mechanisms.

In these environments, engineering considerations usually include:

• end-effector type (e.g., Bernoulli, vacuum chuck, edge-grip variants),

• vacuum feedthrough strategy (where applicable),

• maintenance access design,

• particle control and clean operation protocols,

• and deterministic motion tuned to throughput and safety.

Applications and Use Cases

Semiconductor wafer transfer in vacuum process tools

The most common use case for a vacuum manipulator series such as PHOENIX PLUS is wafer transfer within vacuum semiconductor equipment. This includes staged movement between:

• load locks and transfer chambers,

• transfer chambers and process modules (etch, deposition, anneal, etc.),

• and process modules to integrated metrology steps.

Advanced electronics and thin-film manufacturing

Beyond traditional wafer fabs, vacuum transfer manipulators are used in:

• thin-film coating lines,

• advanced packaging toolchains that employ vacuum steps,

• and specialized R&D vacuum systems requiring high placement repeatability.

Equipment OEM integration and retrofit projects

Vacuum manipulators are also selected by equipment manufacturers for:

• new tool platforms where an integrated vacuum handling robot is required,

• or retrofit/upgrade projects where legacy transfer assemblies are replaced to improve reliability, repeatability, or maintainability.

Advantages / Benefits

High repeatability for stable handoffs

Published repeatability values (on the order of hundredths of a millimeter in the cited materials) support stable robot-to-station handoffs and can help reduce misplacement risk in tightly constrained vacuum tool geometries.

Vacuum compatibility for demanding processes

The cited vacuum compatibility level (5×10⁻⁷ Pa) positions the PHOENIX PLUS family for processes where low-pressure operation is essential and where vacuum-rated design practices are required.

Scalable model lineup

The identification of multiple PHOENIX PLUS models (S25; B31/B33/B35/B39; and mention of a G variant) suggests a lineup intended to cover multiple tool layouts and throughput targets under one family umbrella.

FAQ Section

What is the SIASUN Vacuum Manipulator PHOENIX PLUS Series?

The PHOENIX PLUS Series is a set of vacuum-environment robotic manipulators used to transfer wafers or substrates inside vacuum process equipment, emphasizing repeatable motion and vacuum compatibility.

How does the PHOENIX PLUS Series work?

In typical installations, the manipulator operates inside a vacuum chamber (often a transfer chamber) and moves substrates between stations (load locks and process modules) using controlled multi-axis motion and a vacuum-compatible handling interface. PHOENIX PLUS materials highlight vacuum compatibility and repeatability specifications relevant to this role.

Why is a vacuum manipulator important in semiconductor tools?

Vacuum manipulators enable automated handling without breaking vacuum, which helps maintain process stability, reduce contamination risk, and support high-throughput tool architectures where multiple process modules share a central transfer chamber.

What are the benefits of the PHOENIX PLUS Series?

Commonly cited benefits include high repeatability (e.g., ±0.06 mm for PHOENIX PLUS-S25 and ±0.05 mm for PHOENIX PLUS-B variants in published tables), and high-vacuum compatibility (listed at 5×10⁻⁷ Pa), supporting vacuum process equipment integration.

Summary

The SIASUN Vacuum Manipulator PHOENIX PLUS Series is positioned as a vacuum-compatible transfer manipulator family for semiconductor and advanced vacuum-process automation, with published materials emphasizing model variety, repeatable positioning, and high-vacuum operation capability. By targeting the core requirements of in-chamber substrate handling—precision, vacuum suitability, and configurable deployment—the PHOENIX PLUS Series fits applications ranging from cluster-tool wafer transfer to specialized vacuum manufacturing and R&D environments.
