Nanoimprint Lithography

Processing

E-beam Service

NILT offers nanoimprint lithography service and NILT handles imprinting of both small and large volume orders.
In order to get satisfactory imprint results then the imprint stamp patterns, the imprint polymer and the process paramteres must be designed and optimized for the specific imprint requirements. NILT’s engineers assist customers in all relevant issues to obtain full customer satisfaction:
  • Stamp design considerations
  • Choice of imprint polymers
NILT offers cleanroom processing, complementing the offered NIL and e-beam services.

Examples of processing offered are:
  • Metal deposition
  • Reactive-ion etching (RIE)
  • Deep reactive-ion etching (DRIE)
  • Lift-off
  • Wafer bonding
  • Wafer dicing
  • UV lithography
  • SEM and AFM characterization

 

NILT offers high-end electron beam lithography (EBL) on customer’s substrates according to customer specifications.
E-beam service is made using state-of-the-art 100 keV, Gaussian as well as shaped beam, EBL tools.

E-beam service is as a standard performed on the following substrate formats:
  • 2", 3", 4" and 6" round wafer sizes, thickness up to 2 mm
  • 6" x 6" x 0.25" mask blanks

NIL Imprint Module

Nanolithosolution (NLS) imprint module

The NLS imprint module can be used as a simple add-on to existing UV-aligners allowing you to do nanoimprinting on your aligner. You can switch between normal aligner mode and nanoimprint mode simply by changing the wafer chuck on the aligner - a 2 min operation. Below, read more about the many advantages offered with the NLS imprint module.   Watch the demo video-Click here.
