503 and target 3 form the sealed chamber for being suitable for accommodating deionized water 505, deionized water 505 is for cooling down target 3.Magnetic
Keyholed back plate 501 is located in the sealed chamber, and connects the driving device 502 outside sealed chamber.Magnetron 501 is in driving device 502
Driving under scan target 3, to generate magnetic field near 3 surface of target.In technical process, plasma excitation source 504 is applied
It is biased to target 3, so that it is formed negative pressure relative to the chamber body 1 of ground connection, makes the process gas of such as argon gas in reaction chamber
Body discharges and generates argon ion and electronics.Magnetic field caused by magnetron 501 can extend the motion profile of electronics, electron motion
It constantly collides in the process with ar atmo, ionizes out a large amount of argon ion, the ionization level of target can be increased.Positively charged argon from
Son is attracted at the target 3 of back bias voltage.When the energy of argon ion is sufficiently high, target 3 is hit, metallic atom can be made to escape target
3 surface of material and moving downward is deposited on workpiece to be processed X.
In conjunction with shown in Fig. 2 and 3, the collimator 4 of the present embodiment is set in chamber body 1 and close 1 top of chamber body,
And each region of collimator 4 has different depth-to-width ratios.Collimator 4 and chamber body 1 are coaxial, are with 4 axis of collimator
Center is divided into three regions: central area 41, intermediate region 42 and fringe region 43 from the center to edge.Central area
41 cylindrical region to take 4 axis of collimator as its axis, intermediate region 42 and fringe region 43 are successively to be coated on center
Cylindrical region outside region 41, intermediate region 42 is between central area 41 and fringe region 43.
Chamber body 1 includes side wall 11 and bottom wall 12.In conjunction with shown in Fig. 2 and Fig. 4, central area 41, intermediate region 42, side
Edge region 43 includes multiple through-holes 44 extended along sidewall direction, wherein sidewall direction refers to Z-direction shown in Fig. 2.Through-hole
44 cross sectional shape without limitation, such as can be the shapes such as polygon or round.In Fig. 4, the section of through-hole 44 is positive six
Side shape, collimator 4 are in honeycomb structure.The depth-to-width ratio of multiple through-holes 44 in the same area be it is identical, depth-to-width ratio is
Refer to that the depth of through-hole 44 and the ratio of width D, depth refer to that the length along sidewall direction, width D refer to perpendicular to sidewall direction
Length.
The depth-to-width ratio of through-hole 44 is known as center depth-to-width ratio in central area 41, the deep width of the through-hole 44 in intermediate region 42
Than being known as intermediate depth-to-width ratio, the depth-to-width ratio of the through-hole 44 in fringe region 43 is known as edge depth-to-width ratio.It is deep among the present embodiment
Width is than being greater than center depth-to-width ratio, and intermediate depth-to-width ratio is greater than edge depth-to-width ratio, i.e., intermediate depth-to-width ratio had not only been greater than center depth-to-width ratio, but also
Greater than edge depth-to-width ratio.Center depth-to-width ratio is identical as edge depth-to-width ratio numerical value, i.e. central area and fringe region is having the same

Hole bottom, and more uniformly deposit to the two side walls of deep hole, to improve the film coverage and depth of deep hole bottom
The symmetry of hole sidewall coverage.The metallic atom that collimator 4 generates each region of target 3 carries out different degrees of filtering, rises
To the effect for reducing deposition rate, film growth can be more precisely controlled in thinner thin film deposition processes.Collimator 4
Also increase the back bias voltage of pedestal 2, is conducive to improve film coverage.
In the present embodiment, central area 41, intermediate region 42, fringe region 43 can have identical via area,
That is the cross-sectional area of the through-hole 44 of each region is equal.In this case, the depth of the through-hole 44 of intermediate region 42 should be big
In central area 41 and the depth of the through-hole 44 of fringe region 43, wherein the through-hole 44 of central area 41 and fringe region 43 is deep
Degree is 50mm or more.Central area 41, intermediate region 42, fringe region 43 also can have identical via depth.?
In this case, the via area of intermediate region 42 should be less than the via area of central area 41 and fringe region 43.Collimator
Central area 41, intermediate region 42 and fringe region 43 size can be arranged according to the size of target corresponding region, but in
The sum of the projected area on reaction chamber cross section (X/Y plane in Fig. 2) of heart district domain 41 and fringe region 43 should account for entire standard
Straight device 4 projects 60% or more of the gross area in reaction chamber cross section.
Only exemplary illustration, the present embodiment are not limited to this above.For example, intermediate depth-to-width ratio can be greater than the deep width in center
Than with one of them in edge depth-to-width ratio, and intermediate depth-to-width ratio is bigger by 15% or more than center depth-to-width ratio or edge depth-to-width ratio, this
Sample can also play the symmetrical of the uniformity of raising film deposition, the film coverage of deep hole bottom and deep hole sidewall coverage
The effect of property.In addition, when intermediate depth-to-width ratio is greater than center depth-to-width ratio and edge depth-to-width ratio, center depth-to-width ratio and edge depth-to-width ratio
Numerical value can also be different, but still it is bigger by 15% or more than center depth-to-width ratio and edge depth-to-width ratio to meet intermediate depth-to-width ratio.
