- a very thin TiN film 10 is formed on the side surface of the recess 6, which is difficult to deposit.
- the applied high frequency power is, for example, in the range of 400 to 1000 W (watts).
- the process time is set so that the thickness of the TiN film 10 deposited on the bottom of the recess 6 falls within a range of 2 to 10 nm, for example.

If this process time is shorter than 5 seconds, the effect of the nitriding treatment is insufficient, and not only the barrier property becomes insufficient but also the specific resistance becomes high, which is not preferable. On the other hand, when the process time is longer than 60 sec, nitriding is excessively performed, which is not preferable because not only the barrier property is insufficient but also the specific resistance is increased.

- the recess 6 is filled with the conductive film 9.

- FIG. 5 is a table for explaining the evaluation of barrier properties when a plasmaless annealing process is performed on a TiN film formed by a thermal CVD method or an SFD method, which is a conventional film forming method.
- FIG. 6 is a graph showing the relationship between the plasma nitriding time and the increasing point rate of the sheet resistance (Rs) before and after the plasma nitriding treatment.
- the barrier property in the evaluation is approximately the same as the barrier property of the two-layered barrier layer composed of the Ti film and the TiN film. It can be said.
- a TiN film was formed on a silicon substrate by a plasma CVD method to form a barrier layer, and a Cu film was formed without plasma nitriding treatment.
- a plasma CVD method to form a barrier layer
- a Cu film was formed without plasma nitriding treatment.
- three samples of Comparative Examples 1 to 3 were prepared by changing the flow rate of the TiCl 4 gas as the source gas or changing the process pressure. These samples were annealed for 30 minutes in an Ar atmosphere at 400 ° C. and 10 Torr (1333 Pa).
- the method of evaluation is the same as in Examples 1 to 4. That is, the barrier property was evaluated by measuring the sheet resistance before and after the annealing treatment.

- they are 3.3%, 8.3%, 4.1%, and 0.0%, which are all lower than the standard value of 10%, and the barrier property is greatly increased. It was found that it was improved.
- Each Rs increase point rate (excluding Comparative Example 2) is also represented as a graph in FIG. From the above, it can be seen that in order to improve the barrier property of the TiN film, it is necessary to perform plasma nitriding after the formation of the TiN film by plasma. Further, according to FIG. 6, it can be recognized that the longer the plasma nitriding treatment, the lower the Rs increase point rate and the higher the barrier property. As will be described later, this Rs increase point rate is It is considered that the time is about 30 seconds and the bottom starts and then rises.
- the barrier property can be improved by subjecting the TiN film to plasma nitriding.
- the improvement of the barrier property by the method of the present invention is effective when the thickness of the TiN film is 2 to 10 nm. In other words, it has been found that sufficient barrier properties can be obtained even if the barrier layer is thinned to 2 nm.

- four samples of Comparative Examples 4 to 7 were made by changing the process temperature and film thickness. These samples were annealed for 30 minutes in an Ar atmosphere at 400 ° C. and 10 Torr (1333 Pa). Then, the sheet resistance before and after the annealing treatment was measured as in the previous evaluation experiment, and the barrier property was evaluated. The result at this time is shown in FIG.
- the SFD film formation is a film formation method in which deposition (deposition) and nitridation are alternately repeated while flowing each gas flow rate, and a thin film is laminated over a plurality of layers. And one cycle.
- the plasma nitriding time in the nitriding step is preferably in the range of 5 to 60 seconds. If this time is shorter than 5 sec, not only the Rs value is large, but also the barrier property cannot be sufficiently exhibited. On the other hand, if this time is longer than 60 sec, the Rs value becomes excessively large, which is not preferable. In this case, as shown below, the graph shown in FIG. 6 is also expected to draw a downward characteristic curve, that is, it is presumed that the barrier property is also deteriorated.
- a more preferable range of the plasma nitriding time is in the range of 10 to 40 sec.

次に、以上のように構成されたプラズマ処理装置を用いて行われる本発明の成膜方法の一実施形態について、図1乃至図3を参照して説明する。ここでは、プラズマ処理方法の一例として、Ti膜及びTiN膜を成膜し、その後に窒化処理する場合を説明する。
前述のように、半導体ウエハWを搬入した後に処理容器22内を密閉したならば、Ti膜の成膜が行われる(図3のS1)。まず、ガス供給手段50から、原料ガスのTiCl4 ガスと、還元ガスのH2 ガスと、プラズマ用ガスのArガスとが、それぞれガス導入手段であるシャワーヘッド40に所定の流量で流されると共に、これらの各ガスがシャワーヘッド40から処理容器22内に導入され、且つ、真空排気系28の真空ポンプ32により処理容器22内が真空引きされて、所定の圧力が維持される。
以上のようにしてTi膜8の成膜処理が行われたならば、次に、プラズマを用いてTiN膜(窒化チタン膜)よりなる薄膜を形成する薄膜成膜工程が行われる(S2)。この薄膜成膜工程は、同じ処理容器22内で、前記工程に続いて連続的に行われる。
以上のようにしてTiN膜10の成膜処理が行われたならば、次に、本発明の特徴であるプラズマを用いた窒化工程が行われる(S3)。この窒化工程は、同じ処理容器22内で、前記前工程に続いて連続的に行われる。
以上のようにしてTiN膜の窒化工程が行われたならば、次に、半導体ウエハWが処理容器22内から搬出されて、埋め込み工程が行われる(S4)。この埋め込み工程では、例えば他の成膜装置によって、前記凹部6内を含む半導体ウエハWの表面に導電性材料の成膜が行われる。これにより、図2Eに示すように、前記凹部6内に前記導電性材料が埋め込まれる(埋め込み工程)。
次に、前記実施形態に従ってプラズマ窒化処理されたTiN膜の評価が行われた。その評価結果について説明する。
