Fashion is cyclic. What goes out of fashion today would be fashion tomorrow. Now whatever was the fashion is coming back slowly. I am not talking about the pure fashion news. I am talking about a silicon PCB and a 3D chip with buses through bare silicon between layers. Some start ups are trying to build PCB-like system on a bare silicon. One does it in 3D and the other in 2D. With a high ASIC price and the need for compact logic, this may come as an alternative for many struggling IC makers.
