Raith EBPG 5000+ e-beam lithography tool is in operation since 2003. It has been set-up in a dedicated cleanroom of class 10 (ISO 4) with high precision temperature control at 21 ± 0.1° C. This stability in temperature is a prerequisite for the minimization of thermal drift in the electron optics, and thus, for the excellent performance of the system. The EBPG5000+ is a high performance nanolithography system used to pattern large areas by high-resolution electron beam lithography. It is a vector-scan direct write tool with a Gaussian shaped beam which operate up to 100 keV acceleration voltage with an exposure 125 MHz pattern generator. This instrument has substrate holders to handle samples of 10x10 mm² up to 4" wafers.

Combining raster and concentric writing strategy

By combining raster (longitudinal) and concentric writing, we can acheived very dense photonic crystal in GaAs. The resist is HSQ (180nm thick). The photonic crystal, after etching, is made of holes (diameter 130nm) with a smallest gap (20nm).

Applications

Hybrid nanolaser diode

Realisation of an hybrid indium phospine-on -silicon nano laser diode, by combining 9 level lithography. The realization of the device implies tailoring the writing strategy in order to combine very low current and high current wrinting and the subsequent etching step.
