Method of manufacture of several components on a single body semi - conductor and objects of the music box forms, for its implementation

摘要

Integrated circuit elements e.g. transistors, in a semi-conductor body are electrically insulated from one another by etching a groove 8 into the semi-conductor body between said elements and back-filling the groove with an insulative resin so as to present a substantially smooth supporting surface on said semi-conductor body for application of conductive material forming electrical connections 15 between said elements. Preferably the resin provides a uniform layer 11 over the surface of the semi-conductor body and, before the resin is applied, an oxide layer 2 is formed over the walls of the groove. IMAGE
