DEFINITION

Classification: 438/453

And electrical conductor formation (i.e., metallization):

(under subclass 439) Process including a step of making an electrically conductive member integral to the semiconductive substrate.

(1) Note. The contact may be, for example, directly to semiconductive regions of the substrate or may reside atop the field oxide isolation structure.
