Abstract
1. A method of constructing an electronic device comprising the following steps: processing at least a portion of a first component of said device in a first chamber having an environment free of contaminants harmful to the processed portion; locating a second component of said device in a second chamber, separated from said first chamber by a barrier, and having an environment which may contain said harmful contaminants; protectively covering said processed portion of said first component; breaking said barrier between said chambers; and removing said protective cover from said processed portion during assembly of said first and second components without substantially exposing said processed surface of said first component to said second environment.
