Product Introduction

This compact EFEM configuration supports two load ports around a single atmospheric robot and aligner. Positive-pressure ultra-clean airflow protects opened carriers and wafers during horizontal transfer between the ports and process tool. The two-port layout minimizes tool-front width for metrology or lower-throughput processes.

Key Features

Reduced tool-front width

Two ports provide source and destination positions without the span of larger EFEMs.

Protected wafer handling

Ultra-clean positive airflow surrounds horizontal robotic transfer outside the carrier.

Standards-oriented interface

The front end can be arranged around SEMI-compatible carriers and tool interfaces.

Technical Parameters

Environment	Positive-pressure ultra-clean mini-environment
Wafer Handling	Horizontal atmospheric robotic transfer
Robot Count	One
Aligner	Integrated option
Carrier Interface	SEMI-standard compatible
Carrier Type	FOUP or cassette by process

Customization	Available based on the intended application and operating environment.

Applications

For compact semiconductor process or metrology tools requiring two FOUP or cassette positions. Port pitch, robot reach and tool handoff must be coordinated as one automation envelope.

Solutions for Your Application

A three- or four-port EFEM makes the tool front unnecessarily wide.Use two load ports for the minimum source-and-destination arrangement.

Exposed wafer transfer risks particle deposition.Maintain the positive ultra-clean mini-environment around the atmospheric robot.

Available Options

Configure load-port standard, aligner, carrier ID, ionization, robot reach and automation interface. Final geometry follows the process tool.
