Important! If you cannot launch anything from this database, please follow the step-by-step instructions on the software page.
Please Note: Many models are linked to directly from within the database. When an activity employs our scripting language, Pedagogica, as do some of the "guided" activities, the initial download may take several minutes. Subsequent activities will not take a long time. See this page for further instructions.
What affects the making of an atomic-scale film such as that used in the printing of circuitry? In this activity, students undertake a simulation of the Atomic Layer Deposition (ALD) technique, a CVD process in which two complementary precursors (e.g., Al(CH3)3 and H2O) are alternatively introduced into the reaction chamber, and build an atomic scale film.
Students will be able to:
You might link the model to an animation of ALD as used in manufacturing: http://www.cambridgenanotech.com/animation/
Molecules can be layered on top of precursors to build up the thickness of a film useful in atomic-scale manufacturing.
