METHOD OF MAKING A DEVICE COMPRISING A PATTERNED ALUMINUM LAYER

Chemical vapor deposition of an aluminum layer on a substrate is facilitated by surface activation prior to deposition. Surface activation is at relatively low temperature and results in a hydrated surface; low temperature surface activation is advantageous in the interest of keeping deposition appa...

More Information
Summary:Chemical vapor deposition of an aluminum layer on a substrate is facilitated by surface activation prior to deposition. Surface activation is at relatively low temperature and results in a hydrated surface; low temperature surface activation is advantageous in the interest of keeping deposition apparatus free of additional chemicals, and substrates activated in this manner may be stored for considerable lengths of time prior to aluminum deposition. Among suitable activating agents are organochromium, organosilane, and organoaluminum compounds.
