ABSTRACT:
Deep diodes which extend in straight lines through a silicon wafer are produced by migrating aluminum droplets through the wafer while maintaining a finite temperature gradient through the wafer in the direction of straight line droplet travel, and at the same time maintaining a zero temperature gradient through the wafer in a direction normal to the droplet travel course. Unidirectional heat flow apparatus implementing this method is also disclosed.
