Our longstanding experience with semiconductor processing machinery allows us to design, manufacture, and deliver high-performance hermetically sealed feedthroughs and engineered feedthrough subassemblies with the shortest lead times you’ll find anywhere. Speak to our experts and learn more about our hermetic wire seals, hermetic sealing epoxy, and our electric feedthrough connectors for the semiconductor industry.  We offer solutions for power, signal, and fiber optic signal transmission in UHV environments.  Our epoxy technology offers hermetic seals with low outgassing as well as a wide range of chemical compatibility for critical applications where contamination is a concern.  Our technologies can be combined to offer complete assembly solutions requiring cables, power feedthroughs, wires (including thermocouples), and connectors; the combination can be in the form of a wire assembly or our Portplate multi-port flange assembly. Design the exact connection type that will enable a high reliability electrical connection for long-term use.

Our hermetic feedthroughs are utilized in various types of semiconductor equipment from vacuum chambers to wafer processing systems.  Our epoxy technology creates high-density assemblies for OEM equipment designs.  Douglas Electrical can hermetically seal power, signal and fiber connection points within the same assembly as well as fully-populated printed circuit boards.

Douglas Electrical Components has manufactured customized solutions over the past few decades for the semiconductor industry.  For example, we manufacture sealed thermocouple and shielded cable feedthroughs to monitor temperature and critical process gases, sealed to high current studs to 750 amps.  For wafer transfer drive and motor systems, Douglas offers sealed connector and cable assemblies to communicate low-level power and sensor signals through a single, compact penetration. Our low-outgassing hermetic seals are used in HIVAC containment for a beam mask writing tool.

  • Drop-in replacements for common feedthrough components
EXAMPLE APPLICATIONS
  • Hermetically sealed feedthroughs bring multiple signal, power and air lines through a single vacuum chamber port to fully populated PCBs.
  • High-current power connections for processing chambers using 750-amp StudSeal™ feedthroughs.
  • Compact hermetic power and sensor seals for wafer transfer motor and drive systems.
  • Single or multiple optical fiber feedthrough for optical detection of wafer cassette position in load lock.
  • Pogo pin feed-through for quick and easy mating to contact pads on PCB. Connectorized wire side for quick and accurate installation.
  • Heated paddle subassemblies and multi-cable vacuum penetrations.
  • Fully tested turnkey sub-assemblies for wafer-processing equipment like ion etch tools, ion implant systems and in-line vacuum applications
SEMICONDUCTOR APPLICATIONS OPERATING IN A VACUUM ENVIRONMENT
  • Deposition: Vacuum deposition is a process in which a thin film of material is deposited onto a substrate using a vacuum chamber. This process is used to add layers of materials to a semiconductor wafer during the fabrication of ICs.
  • Etching: Vacuum etching is a process in which a material is selectively removed from a substrate using a chemical etchant and a vacuum chamber. This process is used to pattern the layers of materials on a semiconductor wafer during the fabrication of ICs.
  • Ion implantation: Ion implantation is a process in which ions of a specific element are implanted into a substrate using a vacuum chamber. This process is used to modify the electrical properties of the substrate and is an important step in the fabrication of ICs.
  • Thin film processing: Thin film processing is a group of vacuum processes that are used to deposit, etch, and pattern thin films of material on a substrate. These processes are used to fabricate a wide range of microelectronic devices, including ICs.
  • Packaging: Vacuum packaging is a process in which a device or component is sealed in a vacuum-tight container to protect it from contamination and moisture. This process is often used to package semiconductor devices for storage and transportation.
