The conventional circuit would require approximately 40 separate discrete 1___________, 200 connections, 40 hermetic seals, and 300 separate processing operations with each operation, seal, and connection representing a possible source of failure. However, if all the elements of this circuit are integrated upon one chip of silicon, the 2_____________ of connection drops to about 14. All circuit elements are interconnected inside the package by a process 3_______________ as vapour metallization; instead of 40 hermetic seals there is one, and the three 4_______________ processing operations are reduced to approximately 30.
