Benefits of technology

[0011]The present invention provides a method for depositing a dielectric material. The complete processing time for depositing the dielectric materials is much shortened, as compared with the conventional technique.

Problems solved by technology

It is noted from the above that the complete deposition process for a whole cycle takes considerable time.
Furthermore, since several actions are required, the risk of failure is increased simultaneously.
Consequently, reducing the failure risk and increasing the yield rate become important issues in this industry.

Embodiment Construction

[0030]The present invention will now be described more specifically with reference to the accompanying drawings as well as the associated embodiments. It is to be noted that the following descriptions of the preferred embodiments of this invention are presented herein for the purpose of illustration and description only; it is not intended to be exhaustive or to be limited to the precise form disclosed.

[0031]Please refer to FIG. 4, which is the time diagram showing the pulse-purge deposition method according to the present invention, where the X-axis shows the action contents; while the Y-axis indicates the timing. The actions from top to bottom in the X-axis in FIG. 3 are listed in the followings: action (1′): pulsing the first material; action (2′): purging; and the action (3′): pulsing oxidant O. Form the time-frame perspective as shown in FIG. 4, action (1′) is performed in the time period T1, action (2′) is performed in the time period T2, action (3′) is performed in the time p...

Abstract

A depositing method for a dielectric material is provided, where the dielectric material has the first and the second primary elements, and a single precursor includes the first and the second primary elements. The depositing method includes pulsing the single precursor, purging a redundant part of the single precursor, pulsing an oxidant for oxidizing the single precursor, and purging a redundant part of the oxidant.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a method for depositing a dielectric material, and more particularly to a dielectric material depositing method.BACKGROUND OF THE INVENTION[0002]The dielectric materials are mostly formed via the deposition process in the semiconductor field. If the high dielectric material is applied to the semiconductor, the method of atomic layer deposition (ALD) combined with the pulse-purge method are used to deposit the dielectric materials. At first, the materials are pulsed on the substrate surface where the materials are to be deposited, and then the redundant materials are purged and removed from the substrate.[0003]Usually, the dielectric materials are not directly applied to the substrate, but a chemical compound is used as a precursor. After then, the oxidation or reduction reaction (usually the oxidation) is processed to obtain the final dielectric material.[0004]Please refer to FIG. 1, which is the schematic diagram showing ...
