Abstract (en)

[origin: WO0106554A1] The resistance of a polysilicon structure is often reduced by providing it with a silicide layer. However this presents a production problem in terms of only siliconizing certain polysilicon layers. Others, such as those that are to be used for resistors, are not siliconised. The invention therefore provides a simple method for the selective siliconization of polysilicon areas in integrated semiconductor structures.
