Description

Special-shaped target material and magnetron sputtering process
Technical Field
The invention relates to the PVD (physical vapor deposition) field, in particular to a special-shaped target material for magnetron sputtering and a magnetron sputtering process.
Background
The magnetron sputtering process belongs to one of PVD processes; the magnetron sputtering process is a common thin film deposition technology;
in the magnetron sputtering process, a target material is used as a cathode, and a substrate is used as an anode; the back of the target is provided with a magnet so as to generate a magnetic field in the space of the front of the target; applying a negative bias to the target so that the gas is broken down to generate a discharge phenomenon; electrons collide with atoms (such as Ar atoms) of the introduced process gas in the process of flying to the substrate, and positive ions (such as Ar+ ions) and electrons with charge energy are ionized; the charged positive ions are accelerated to fly to the target material and bombard the surface of the target material under the action of an electric field, so that the target material is sputtered to generate sputtered particles, and the substrate on which the sputtered particles fly to the opposite surface of the target material forms a film on the surface of the substrate; electrons are restrained by a magnetic field in the space of the front of the target and are restrained in a plasma area close to the front of the target, and collide with atoms of the process gas for a plurality of times; as the electron energy decreases it gradually moves away from the front of the target and eventually also deposits onto the substrate.
The target material commonly used at present is a planar target material; there are mainly two problems in depositing a thin film on the surface of a substrate;
1) The film thickness uniformity of the thin film is poor; typically, the film in the middle region of the substrate is thicker than the film in the edge region of the substrate.
2) In the existing semiconductor technology, the substrate needing magnetron sputtering coating comprises a planar substrate and a substrate with a microporous structure on the surface; with the continuous development of semiconductor devices, the hole structure is continuously developed towards the direction of increasing the depth-to-width ratio (i.e. the depth of the hole is larger than the caliber), and in the edge area of the substrate, sputtered particles are more difficult to reach the side wall and the bottom of the micropore, so that the difficulty of plating a uniform film on the inner wall of the micropore is greater.

As shown in fig. 2, an embodiment of the present invention proposes a profiled target, including:
a planar main portion 10, the planar main portion 10 being provided so as to oppose the substrate 30;

compared with the sputtering angle distribution of single sputtering particles of the traditional planar target, the target is added with the inclined auxiliary part 20, and sputtering particles generated by magnetron sputtering can fly to the substrate 30 from more different angles; the film is easier to uniformly distribute on the surface of the substrate 30, and a film with uniform thickness can be formed on the surface of the substrate 30; the sputtering particles with multiple sputtering angles are easier to plate a uniform film in micropores of the edge area of the substrate, so that a better hole filling effect is obtained.
In a specific embodiment, the planar main portion 10 is circular, and the inclined auxiliary portion 20 is annular disposed around the planar main portion 10; the profiled target of this construction can be matched to a conventional circular substrate 30.
In another specific embodiment, the planar main portion 10 is rectangular, and the inclined auxiliary portions 20 are rectangular distributed on two sides of the planar main portion 10; the profiled target of this construction can be matched to a rectangular substrate 30.
Further, the included angle between the inclined auxiliary part 20 and the plane main part 10 is 25-35 degrees, and the film thickness uniformity of the special-shaped target material in the included angle range is excellent during magnetron sputtering.
Further, the width of the planar main portion 10 is greater than the width of the substrate 30, but not more than 110% of the width of the substrate 30;
further, the overall width of the planar main portion 10 and the inclined auxiliary portion 20 is 130% -160% of the width of the substrate 30;
the flat main portion 10 and the inclined auxiliary portion 20 having the widths described above can ensure uniformity of film thickness of the plating film of the substrate 30 and uniform thin film plating in the micro holes of the edge region of the substrate.
The special-shaped target is a metal target, and the material of the special-shaped target can be metal such as aluminum, copper, titanium or metal alloy.

watch III
In fig. 4, the thickness d1= 242.90nm of the thin film 50 is plated in the substrate microwells by planar target magnetron sputtering, and in fig. 5, the thickness d1= 327.52nm of the thin film 50 is plated in the substrate microwells by profiled target magnetron sputtering; it can be seen that the film 50 of fig. 4 is discontinuous and has voids; the film 50 in fig. 5 is continuous and thick, and the effect of plating the micropores on the edge area of the substrate is better and the hole filling effect is better by magnetron sputtering of the special-shaped target.
