  • Patent number: 4409724
    Abstract: Method of fabricating a display with silicon integrated circuits included on the same monolithic structure and the flat panel display produced thereby. The display which may be of the liquid crystal or electrochromic type, for example, is formed as an x-y matrix display having individual address transistors respectively asociated with each of the display units or pixels. The substrate is preferably of transparent material, such as quartz or a glass plate, on which a polysilicon layer is disposed. The polysilicon layer is patterned to provide a plurality of islands which are subjected to a laser annealing treatment at an intensity sufficient to cause recrystallization thereof. The polysilicon material in the islands is converted by the laser annealing to crystalline silicon having an enhanced electron mobility characteristic such that a matrix array of address transistors in the form of MOSFETS can be fabricated in the individual islands.
