"cronichles from the lab" Optical microscope (Nikon eclipse ME600) image of a faulty <a href="http://en.wikipedia.org/wiki/Lift-off_(microtechnology)" rel="noreferrer nofollow">lift-off</a> of a thin gold film from a lithium niobate (crystal) surface. Gold should have been removed completely from the areas where it's wrinkled because, by <a href="http://en.wikipedia.org/wiki/Photolithography" rel="noreferrer nofollow">photolitography</a>, a layer of <a href="http://en.wikipedia.org/wiki/Photoresist" rel="noreferrer nofollow">photoresist</a> should have protected that area on the crystal surface. But the photoresist was clearly not enough. On the left, the <a href="http://en.wikipedia.org/wiki/Interdigital_transducer" rel="noreferrer nofollow">IDTs</a> which I wanted to fabricate can be seen. Immagine al microscopio ottico (Nikon eclipse ME600) del <a href="http://en.wikipedia.org/wiki/Lift-off_(microtechnology)" rel="noreferrer nofollow">lift-off</a> fallace di uno strato d'oro dalla superficie di niobato di litio (un cristallo). L'oro avrebbe dovuto essere rimosso da tutte le aree in cui è increspato poiché, nella tecnica di <a href="http://it.wikipedia.org/wiki/Litografia_(elettronica)" rel="noreferrer nofollow">litografia ottica</a>, uno strato di <a href="http://it.wikipedia.org/wiki/Photoresist" rel="noreferrer nofollow">photoresist</a> avrebbe dovuto proteggere quelle aree del cristallo. Ma il photoresist è stato chiaramente troppo poco! Sulla sinistra si possono vedere i <a href="http://en.wikipedia.org/wiki/Interdigital_transducer" rel="noreferrer nofollow">trasduttori</a> che stavo microfabbricando. |
