Stencil-Nanopatterned Back Reflectors for Thin-Film Amorphous Silicon n-i-p Solar Cells

Jürgen Brugger, Christophe Ballif, Franz-Josef Haug, Andreea Veronica Savu, Oscar Vazquez Mena, Mona Julia Katharina Klein, Céline Pahud

We fabricated amorphous silicon n-i-p solar cells with two types of nanopatterned back reflectors using stencil lithography. One reflector type has a plasmonic grating that is embedded in the ZnO layer; the other one has a metallic grating patterned on top ...

SiN membranes with submicrometer hole arrays patterned by wafer-scale nanosphere lithography

Jürgen Brugger, Andreea Veronica Savu, Oscar Vazquez Mena, Harry Heinzelmann, Mona Julia Katharina Klein, Nicolas Blondiaux, Raphaël Pugin, Franck Montagne

In this work, nanosphere lithography was integrated with standard microfabrication for the wafer-scale fabrication of silicon nitride (SiN) membranes with arrays of submicrometer holes. A monolayer of polystyrene (PS) beads with a mean diameter of 428 or 5 ...

GOLD MEMBRANES WITH LARGE ARRAYS OF SUB-µm HOLES FABRICATED BY WAFER-SCALE NANOSPHERE LITHOGRAPHY

Jürgen Brugger, Harry Heinzelmann, Mona Julia Katharina Klein, Raphaël Pugin

Gold membranes with large arrays of sub-µm holes were fabricated and optically characterized. The fabrication is a combination of a bottom-up, self-assembly based patterning technique, Nanosphere Lithography (NSL), and standard microfabrication. This was a ...

Wafer-Scale Fabrication of Thin SiN Membranes and Au Films and Membranes with Arrays of Sub-um Holes Using Nanosphere Lithography

Mona Julia Katharina Klein

In this thesis, the wafer-scale fabrication of SiN membranes, Au films and Au membranes with arrays of sub-µm holes is described. Two conceptually different processes (1) and (2) were developed, both of which are based on nanosphere lithography (NSL) with ...

Inexpensive and fast wafer-scale fabrication of nanohole arrays in thin gold ﬁlms for plasmonics

Jürgen Brugger, Harry Heinzelmann, Mona Julia Katharina Klein, Bernard Wenger, Raphaël Pugin

In this paper, a fast and inexpensive wafer-scale process for the fabrication of arrays of nanoscale holes in thin gold ﬁlms for plasmonics is shown. The process combines nanosphere lithography using spin-coated polystyrene beads with a sputter-etching pro ...

Nanoporous SiN membranes patterned by wafer-scale nanosphere lithography

Jürgen Brugger, Andreea Veronica Savu, Oscar Vazquez Mena, Harry Heinzelmann, Mona Julia Katharina Klein, Raphaël Pugin, Franck Montagne

Nanoporous SiN membranes are interesting for a number of applications, e.g. stenciling, filtration, or tissue engineering [1-3]. The patterning of the pores requires a high resolution lithographic tool. Focused ion beam milling or e-beam lithography fulfil ...
