Glovebox Adaptors

The Mini SPECTROS features a new and improved glovebox mounting system and sliding door.

The new Mini SPECTROS door configuration means that there is now no need for difficult installation of removing doors. With its new telescopic rail fast and easy installation is now possible.


Kurt J Lesker is able to offer a wide array of standard and custom glovebox suites, from a standard 2 port and 4 port arrangement, to custom lengths and Depths.

Glovebox Specifications

  • Feedthrough Connectors: Four standard KF40 connectors for customer use.
  • Shelves: Two storage shelves can be used to store samples and small labware.
  • Gas Filter: Two 0.3pm filters installed at the circulation inlet and outlet.
  • Foot Switch: Adjusts the pressure inside the glovebox.
  • Purifier: Contains copper-based catalyst for removing oxygen and zeolites for moisture removal.
  • The oxygen and water capacities are 30 L and 2.0 kg, respectively and the purifier can be regenerated.
  • Solenoid purge valve: For automatic purge, this also serves as pressure relief valve.
  • Circulation Blower: Fuji Blower, low noise, flow rate 45m3/h

  • Other accessories upon request


The Mini SPECTROS offers two types of high vacuum pumping on its process chamber a Pfeiffer 790 L/s turbomolecular pump as standard or an optional Brooks CTI-8F 1500 L/s cryo pump. Either pump is an option for any of the deposition configurations for the Mini SPECTROS. The Pfeiffer 790 L/s being a good choice for overall cost effective high quality pumping particularly for Low Temperature and Thermal evaporations. The Brook CTI-8F finding use in applications that require the lowest vacuum possible particularly for thermal evaporation and electron beam applications.

The chart to the right demonstrates average expected pumping performance by pump type for an outfitted Mini SPECTROS process chamber that is clean and dry with (3) Torus 3" Mag-keeper sources installed and a 3' long 1.5" metal flex bellows roughing line.

Pump curves for a clean dry and empty Mini SPECTROS. Pumping performance is depending on chamber conditions and components installed.

The Mini SPECTROS was re-designed to mount the high vacuum valve directly to the process chamber without the 4" half nipple and now accommodates a larger 790 L/s pump or CTI8 pump. This allows the Mini SPECTROS to reach lower base pressures and faster pumpdown times than similarly equipped systems.


Torus® sources are operated at typical sputtering pressures (< 20 mTorr) and utilize Si wafers for deposition. SiO2 Target run with RF Power, film thickness >=500Å. Al Target run with DC Power, film thickness >=1500Å. Ni Target run with High Strength Torus® & DC Power, film thickness >=1500Å.

KJLC electron beam deposition runs utilize Si wafers for deposition. Ti evaporant material with film thickness >=1500Å.

  • All Films are measured on a properly calibrated Profilometer, Reflectometer or Ellipsometer (if applicable).
  • Measurement points are taken starting at the center of the substrate and then radially outward every 0.5 inches (12.7mm), nominally (reference figure to the right).
  • Uniformity calculation formula is: ((Max - Min) / (2 x Avg)) x 100% with a 0.2 inch (5mm) edge exclusion.

KJLC E-beam sources are also designed to eliminate unnecessary o-rings, seals, and feedthroughs to lower pumpdown times and provide excellent base pressures. Only three feedthrough's are required for the KJLC E-beam source and there is no dynamic water to vacuum o-ring seal in this design which greatly reduces the risk of a water leak in the vacuum chamber.

Thermal evaporation sources typically centered on the substrate fixture have been moved to the outer edges of the fixture in the Mini SPECTROS to allow for better uniformities. The fixtures allow a source adjustment of up to an inch to allow for optimization to a particular application.

The Mini SPECTROS is one of Kurt J. Lesker's most versatile thin film deposition systems offering single and multi-technique deposition options including LTE Evaporation, thermal evaporation, magnetron sputtering (Torus), and electron beam.

The Mini SPECTROS houses KJLC Low Temperature Evaporator. With its unique plugin base that allows for easy access to refill the crucible and easy removal for cleaning and maintenance.

Only KJLC offers Mag-Keeper sputter sources with zero o-rings in the cathode body and a magnetically coupled target to allow for easy target changes. Our "patent pending" cooling well design enables operation at power densities ≥ 200 watts/.in2. This cathode is designed to sputter up to a 0.375" thick targets. The high strength design is able to sputter up to a 0.125" thick Fe target with 3" and 4" cathodes, or 0.0625" thick Fe target with 2" Mag-Keepers. Without a hold down clamp or dark space shield this cathode is capable of running as low as ≤ 1mTorr. The unique dome shutter design eliminates the need for additional cross contamination shielding required with standard flip or swing shutters.

Architecture Overview

KJLC® eKLipse™ Control Software

Kurt J. Lesker Company® eKLipse™ Controls Software is utilized on all KJLC platforms. The eKLipse™ controls platform utilizes a .NET application running on a Windows PC for its User Interface and Recipe Editor. Equipment automation is accomplished via a standalone Real Time Controller.

  • Scripted Recipe Builder – A more traditional "scripted" recipe editor exposes more details for setting or checking the value of any system component during a process.


This control platform was developed by <strong>KJLC's global engineering team</strong> and is supported by <strong>KJLC global service center</strong>.
  • Real Time Controller – The system operates independently of the Windows software package and will continue the recipe should the software / computer malfunction.
  • Independent Thermal Evaporation Thin Film Control – There is no third party software requiring a "handshake" or "handoff" between the Systems Manufacturers software and the thin film controller's software.

Unlimited Recipes, (import/export capable)

  • Unlimited recipes with user security level features
  • Recipe import/export capability (for transferring recipes between similarly equipped tools)
  • Any recipe step can be configured to allow the user to alter a value, enabling process condition changes, without affecting the master recipe. As an example, at the time of execution, the recipe can prompt the user for the desired deposition thickness, or power setting.
