2024-12-20 to 2025-01-02: Reduced Holiday Operations

Dear Birck Research Community,

The Purdue winter recess begins effective Friday afternoon December 20th and concludes Thursday morning, January 2. The university is officially closed during this time. As we have done in past years, the Birck Nanotechnology Center will remain available for research but will be unstaffed and hazardous gasses will be unavailable. Lab work may otherwise proceed, though any fume hood work must be done with someone else present in the same laboratory or cleanroom bay (the "buddy" system). Click the link above to get more detail about equipment conditions and rules.

Refer to the Material and Process Compatibility page for information on materials compatible with this tool.
Equipment Status: Set as UP, PROBLEM, or DOWN, and report the issue date (MM/DD) and a brief description. Italicized fields will be filled in by BNC Staff in response to issues. See Problem Reporting Guide for more info.

Overview

General Description

The Suss SB6e VAC Substrate Bond Aligner is a universal tool for bonding processes for micro electro-mechanical system applications such as: Anodic Bonding (AB) Silicon Fusion Bonding (SFB) and Thermal Compression Bonding (TCB). After alignment on the BA 6 the substrate stacks are mechanically clamped using the transport fixture for further processing in the SB6e chamber.

Specifications

4 inch wafer size for bonding
Vacuum down to 5x10^-5 mbar.
Over pressure up to 3 bar absolute
Flexible process control using Windows NT with data recording and analysis
Optimized bonding routines can be replicated
