DEVICE FABRICATION FOR GRAPHENE & 2D MATERIALS

1st AUGUST 2019 | 15:00 BST

WAFER SCALE DEVICE FABRICATION AND ELECTRICAL CHARACTERISATION FOR GRAPHENE & 2D MATERIALS

Hosted by Oxford Instruments Plasma Technology in partnership with Raith Gmbh and das-Nano Onyx

Raith das-Nano

It has been almost 15 years since the seminal experiments on uncovering the fascinating properties of graphene. What started as playground for fundamental physics studies has now evolved into a healthy wave of development activities to harness the superlative properties of this fascinating class of materials. In particular, applications in integrated photonics, light emitting devices and new channel materials for more-than-moore technologies are showing promising value propositions over incumbent solutions.

This webinar is aimed at providing an overview of wafer scale device fabrication and characterization technologies that would drive development of graphene and 2D materials based technology to the next stage of technology readiness. We will cover three aspects of graphene/2D device development work i.e., materials fabrication, lithography and non-destructive electrical characterisation in the following talks:

WAFER SCALE DEVICE FABRICATION TECHNOLOGY FOR GRAPHENE & 2D MATERIALS | Dr Ravi Sundaram, Oxford Instruments

Vapour deposition techniques have become the workhorse for all device fabrication based on graphene and other 2D materials. For successful scaling up of prototypical applications demonstrated to date, technologies and processes for large area deposition of these materials need to be developed. In this talk I will first give an overview of lab to fab technologies and processes developed at Oxford Instruments towards growth of Graphene, other layered materials and heterostructures by CVD and ALD followed by our developments in technology for device fabrication processes such as dielectric deposition by ALD and device pattern etching by RIE and ALE.

WAFERSCALE NANOFABRICATION OF GRAPHENE BASED DEVICES BY EBL | Dr Frank Nouvertne, Raith Gmbh

Electron beam lithography (EBL) systems have proven to be flexible nanofabrication tools enabling a broad range of nanotechnology applications. They are regarded as a “must have” in today’s nano R&D-based laboratories of various disciplines. These EBL techniques routinely provide nanopatterning resolution with sub 10nm feature sizes. The fundamentals of electron beam lithography and related subsequent essential process technology steps for nanodevice fabrication will be described. Emphasis will be given on a number of various applications, showing both fundamental graphene research & advanced (waferscale) graphene nanodevice applications.

THz BASED NON-CONTACT MOBILITY, CONDUCTIVITY MEASUREMENTS ON WAFER SCALE | Dr Israel Arnedo, das-Nano S.L.

In this talk, I will explain how the combination of the particular features of THz waves introduces a new way of seeing what was not visible before. This technology has been implemented in ONYX, the first system in the market designed to provide a full-area non-destructive characterization of graphene, thin-films, and other 2D materials covering the gap between the macro and the nanoscale tools. Its principle of operation, main features and possible applications will be detailed. Big industry players and research institutions are already using our terahertz-based devices, such as Onyx, implementing it in their manufacturing processes and quality control.
