Filed: 1964-11-30
Abstract: <PICT:1046840/C6-C7/1> A semi-conductor substrate is used to support an assembly of discrete devices. Spaced perforate layers of conductive material are deposited on the substrate and individual layers of semi-conductor material are formed over the conductive layers by epitaxial growth-nucleation occurs through the holes.  The semi-conductor devices are formed by diffusion into, alloying to, or epitaxial growth on the individual layers.  Each conductive layer forms a conductive link between devices in the associated semi-conductor layer.  In the embodiment given a gallium arsenide body 5 shaped as shown is etched and electroplated overall with rhodium 8 to a depth of about 1 m .  A layer of this thickness is perforate. The plated body is given a coating of n-type germanium by disproportionation of GeI2 and the body lapped and polished to leave the structure of Fig. 2E (not shown).  Dots of material are alloyed into the germanium strips 9 to provide abrupt junctions. A lead is connected to each of the alloyed dots to complete the array of diodes.  A co-ordinate array could be made by epitaxial growth in trenches in both the x and y directions on the substrate.  In Fig. 1 (not shown) a germanium wafer cut with (111) orientation is provided with a coating or carbon deposited by thermal decomposition of propane. Germanium areas are deposited each over a respective hole 3a, 3b made in the carbon layer. Microscopic examination shows that germanium both directly over and around each hole is epitaxial with the substrate.
