Description

The manufacture method of semiconductor device
Technical field
The present invention relates to technical field of manufacturing semiconductors, the manufacture method of particularly a kind of metal-oxide semiconductor (MOS) (MOS) device.
Background technology
Metal silicide plays important effect in the VLSI/ULSI device technology.Self-aligned silicide (Salicide) technology has become one of key manufacturing technology that forms metal silicide in the recent period in ultrahigh speed CMOS logic large scale integrated circuit.It provides many benefits for the manufacturing of programmable logic device.This technology has reduced the film resistor of source/drain electrode and gate electrode simultaneously, has reduced contact resistance, and has shortened the RC delay relevant with grid.In addition, it also allows to improve the device integrated level by increasing circuit package density.In self-aligned technology, on source, the drain region of the MOSFET that constitutes by the impurity diffusion layer that is formed on the Semiconductor substrate and the grid that constitutes by polysilicon, form metal and semiconductor for example the reaction product of silicon (Si) be metal silicide.Metal silicide can be used to provide the contact-making surface between metal wire and substrate contact region territory, for example the connection between source electrode on polysilicon gate, the silicon substrate and the drain electrode.Adopt metal silicide can access good low resistance contact, reduce the contact hole of upper layer interconnects structure and the contact resistance of each utmost point of transistor.
Need be when adopting self-registered technology on the surface of the sidewall spacer (offsetspacer) in substrate surface, the grid outside and the top portions of gates surface form the autoregistration barrier layer (Salicide Barrier, SAB).Sidewall spacer is to be included in silica that gate side forms and the ON structure of the silicon nitride that forms at this silicon oxide surface.Application number is that 200410076817.3 Chinese patent application has been introduced a kind of sidewall spacer structure of MOS device and the formation method of metal silicide.Fig. 1 to Fig. 6 forms the generalized section of metal silicide for the MOS device.As shown in Figure 1, have grid oxic horizon 101 and grid 106, the gate surface damage that when gate side is formed with the very thin oxide layer of one deck 105 with reparation etching grid, causes at substrate 100.Form the sidewall spacer of forming by silicon nitride 105, silica 103 and another layer silicon nitride 102 at oxide layer 105 outer surfaces.Wherein the material of silicon oxide layer 103 for deposit forms under lower temperature low temperature oxide (Low Temperature Oxide, LTO).
Then, as shown in Figure 2, deposit forms autoregistration barrier layer 107, and this layer covers substrate 100 surfaces, sidewall spacer surface and top portions of gates surface.By photoetching, the described autoregistration of etching technics patterning barrier layer 107, form the opening 110,120 and 130 of corresponding grid, source electrode and drain metal silicide position, as shown in Figure 3.Subsequently, as shown in Figure 4, plated metal and process thermal annealing form grid, source electrode and drain metal silicide 111,121 and 131 in opening.
