Abstract:

Work aimed at reducing the reverse current is described which includes work on etching techniques, surface protectants, dicing, and mounting. A new time-saving diffusion technique using separate predeposition and redistribution steps is described. The foil press junction formation technique was incorporated in the engineering line and the initial difficulties experienced are described. Three lots are evaluated and various characteristics plotted showing the need for a tighter process control. The initial reliability data from high temperature storage is analyzed showing the reverse current characteristics as the only potential catastrophic failure candidate. Author
