Definitions
- CVD chemical vapor deposition
- a manufacturing method of a film formed by the method is used for a semiconductor device using a film manufactured by the method of the present invention.
- the problem of signal delay is becoming more serious as the speed and integration of semiconductor devices increase.
- the signal delay is expressed as the product of the wiring resistance and the capacitance between the wirings and between the layers.
- the dielectric resistance of the interlayer insulating film is reduced along with lowering the wiring resistance. Lowering the rate is an effective means.
- a B_C_N bond is formed on the surface of an object to be processed by plasma CVD in an atmosphere containing a carbon-based gas, a borazine, and a plasma-based gas.
- a method for forming an interlayer insulating film is disclosed. Further, it is also disclosed that the interlayer insulating film has a low dielectric constant (see, for example, Japanese Patent Laid-Open No. 2000-058538 (Patent Document 1)).
- borazine is used as a CVD raw material, so a film having a low electrical conductivity and a high mechanical strength can be formed, but these properties are not sustained because of poor water resistance. There was a problem. Furthermore, in the heat treatment associated with manufacturing a device using a substrate on which a film has been formed, a gas component is generated from the film, which has a problem of adversely affecting the device manufacturing process.
