METHOD FOR PRODUCING RESISTORS IN INTEGRATED CIRCUITS Russian patent published in 2001 - IPC

Abstract RU 2170474 C2

FIELD: microelectronics; integrated circuit manufacture. SUBSTANCE: proposed method involves formation of insulating layer on silicon plate surface, evaporation of amorphous silicon layer, and formation of resistors in the latter. Prior to forming resistors in amorphous silicon layer the latter is annealed at temperature higher than that for producing next resistors and integrated-circuit structure regions. Proposed technology provides for better reproducibility of polysilicon layer properties to produce resistors or desired ratings due to selection of adequate temperature for additional annealing. EFFECT: increased yield percentage. 4 cl
