AMAT 0090-76110 VME PCB
Product Name
AMAT 0090-76110 Industrial-Grade VME Bus-Based Control & Signal Interface PCB Module
(Referred to as “AMAT 0090-76110 VME Module” for short, it belongs to Applied Materials’ (AMAT) Semiconductor Equipment Control product line. Tailored for semiconductor manufacturing processes—such as wafer etching, deposition, and inspection—it functions as a dedicated VME (VersaModule Eurocard) bus-compatible printed circuit board (PCB) module. It enables seamless communication between AMAT’s semiconductor process tools (e.g., Centura® etching systems, Endura® deposition platforms) and upper-level control systems, while providing precise signal conditioning for process-critical sensors and actuators.)
2. Product Description
The AMAT 0090-76110 VME PCB module addresses the demand for high-reliability, bus-compatible control in semiconductor manufacturing environments (e.g., real-time process parameter monitoring in wafer fabrication, precision actuator control for deposition chambers, and data synchronization between process tools and factory automation systems). It adheres to the VMEbus IEEE 1014-1987 standard, featuring a ruggedized PCB design with gold-plated connectors, high-speed signal traces, and ESD-protected components—delivering signal transmission accuracy of ≤±0.05% FS and supporting up to 16 configurable analog/digital I/O channels.
This design effectively resolves key challenges in semiconductor manufacturing: it ensures stable data exchange via the VMEbus (critical for time-sensitive process control), withstands the cleanroom and high-precision manufacturing environment (low particle emission, corrosion resistance), and provides isolated signal processing to avoid cross-talk between sensitive process sensors. Its core advantages include:
- VMEbus Compliance & System Integration: Fully compatible with the VMEbus 32-bit data/address architecture (up to 40MB/s data transfer rate), enabling plug-and-play integration with AMAT’s VME-based control chassis (e.g., AMAT 0090-76000 series). It supports both master and slave operation modes, allowing it to either initiate data requests (as a bus master) or respond to commands from the main controller (as a slave)—ensuring seamless synchronization with other VME modules (e.g., power supplies, motion controllers) in the process tool.
- Precision Signal Processing for Semiconductor Processes: Features 8 analog input channels (optimized for low-noise process sensors, such as pressure transducers, temperature RTDs, and gas flow meters) and 8 digital I/O channels (for actuator control, interlock signals, and status monitoring). Analog inputs include built-in low-pass filters (1kHz cutoff) and 16-bit ADCs, ensuring accurate capture of micro-scale process variations (e.g., ±0.1mTorr pressure fluctuations in etching chambers). Digital channels support 24V DC operation with ESD protection (±15kV contact) to safeguard against
