PRE-301B-CE

Brooks Automation / PRI Automation Atmospheric Wafer Pre-Aligner

About this part

PRE-301B-CE is a three-axis atmospheric semiconductor-wafer pre-aligner from the Equipe/PRI product line subsequently supplied under Brooks Automation. It optically measures the wafer edge, determines center offset and flat-or-notch orientation, and uses radial, theta, and vertical motion to center and orient the wafer for robotic transfer. The PRE-301 family supports 200 mm and 300 mm wafers, with 150 mm capability offered as an option, and is nominally configured for pin loading with a blade end effector

Configurations vary. Verify the exact unit before choosing a replacement.

Specifications

Identification
Exact modelPRE-301B-CE
Product lineEquipe/PRI PRE-300-series atmospheric pre-aligner
Function
Primary functionDetermines wafer center and flat-or-notch orientation, then centers and rotationally orients the wafer for handling
Motion
Alignment axesThree servo axes: radial axis for lateral centering, theta axis for chuck rotation, and vertical axis for raising and lowering the transfer pins
Wafer handling
Supported wafer sizesPRE-301 family: 200 mm and 300 mm; 150 mm capability optional
Nominal loading arrangementPRE-301 family: pin loading with a blade end effector; PRE-300/PRE-301 loading mode can be changed through pin-height software settings when the correct end effector is installed

Regulatory
CE configurationThe -CE identifier denotes a CE-oriented configuration; the manufacturer manual directs users to confirm compliance from the CE mark on the individual unit

PRE-300 and PRE-301 model relationship

The manufacturer manual describes PRE-300 and PRE-301 as the same three-axis, large-wafer platform with different nominal loading setups. Loading type can be changed through the documented pin-height settings when the corresponding end effector is installed.

Alignment operation

During alignment, the chuck rotates the wafer between an LED source and a CCD array. The controller correlates encoder position with the measured wafer edge, calculates the center-offset vector and flat-or-notch angle, uses the radial and vertical pin mechanisms to center the wafer, and rotates the chuck to the programmed orientation.
