A flexible video display apparatus and a method for making the same. The
flexible video display comprises a silicon layer containing at least a
portion of the control and display circuitry, a display layer, and a
flexible layer. Other layers, such as an insulating layer for dielectric
isolation of the semiconducting devices, may be added. To make the
flexible video display, display and control circuitry are formed in a
silicon-on-insulator wafer. A polymer layer is then formed on the wafer
and electrically conductive portions are formed to interconnect the
polymer portions to the control electronics, thereby forming the display.
Next, a flexible layer is formed on the display layer and patterned if
desired. A handle wafer is then bonded to the topside of the wafer so
that the backside can be partially removed by mechanical, chemical, or
chemical-mechanical means. Finally, the handle wafer is removed leaving
the flexible display.
