Vacuum chuck.The wafer mounting apparatus can provide stable and lasting pull of vacuum in wafer solution bonding process to be come firmly
Fixed wafer, avoids wafer from surprisingly falling off from the wafer mounting apparatus.
Background technique
In the field of semiconductor crystal wafer manufacture, wafer solution is bonded (Debonding) processing procedure mainly by wafer (Wafer)
It is separated with carrier (Carrier), so that wafer can be allowed to carry out subsequent processing procedure.In the wafer solution bonding process, phase
The wafer and carrier mutually adhered are fixed on a wafer susceptor together, are then bonded (Laser through laser solution
Debonding), heat detaches the modes such as (Thermal Slide) or mechanical force removing, makes being bonded between the wafer and carrier
Glue loses adherence or is destroyed, and then removes carrier above the wafer through suction means.Removing the carrier
During, if the wafer susceptor is general vacuum chuck (Vacuum Chuck) or edge clamps chuck (Clamp
Chuck), it is difficult to firmly wafer is tightly fastened on pedestal, it is possible to wafer be caused to generate landing on the base or loosen.
Summary of the invention
The utility model creator asks in view of wafer from be easy unexpectedly to loosen or slide from existing wafer susceptor
It is insufficient with missing to improve its for topic, and then creates a kind of wafer mounting apparatus and its fixed pedestal and wafer vacuum sucker.
The utility model main purpose is to provide a kind of wafer mounting apparatus, can mention in wafer solution bonding process

The utility model wafer mounting apparatus 1 can connect the vacuum pump of an offer pull of vacuum can adsorb and fix crystalline substance
Circle is implemented to execute the wafer solution bonding system the following are the utility model wafer mounting apparatus 1 to execute wafer solution bonding process
The operating instruction of journey.
Fig. 9 and Figure 10 is please referred to, when executing the wafer solution bonding process, the wafer 90 of 80 lower section of a carrier is placed
On the annular support flange 23 of wafer vacuum sucker 20, the vacuum pump exports pull of vacuum to the vacuum tank 200 at this time
It is interior, wafer 90 is firmly adsorbed using a vacuum room is formed by between the wafer 90 and vacuum tank 200, forces wafer 90
It can be tightly fixed on the wafer vacuum sucker 20.
Figure 11 is please referred to, it is after 80s in the absorption wafer 90 and the carrier, (Laser is bonded with laser solution
Debonding), heat detaches the modes such as (Thermal Slide) or mechanical force removing and separates the carrier 80 and the wafer 90,
And remove the carrier 80.
Figure 12 is please referred to, the carrier 80 is being removed and is completing the solution bonding process of the wafer 90 and the carrier 80
Afterwards, the vacuum pump stops output pull of vacuum, at the same thimble 45 by the driving component 41 driving and stretch out upwards simultaneously
The wafer 90 is ejected outside the vacuum tank 200 from the wafer vacuum sucker 20, to supply other mechanical arm will
The wafer 90 is moved to elsewhere and carries out follow-up process.The utility model wafer mounting apparatus 1 is equally applicable for needs will be brilliant
The processing procedures such as cleaning, the etching that circle 90 is tightly fastened.
The utility model wafer mounting apparatus 1 has at least following advantages:
It manufactures and can moderately deform under stress with elastic material 1. the wafer vacuum sucker 20 is whole.Due to the crystalline substance
Circle vacuum chuck 20 only contacts 90 bottom surface periphery of wafer with annular support flange 23, and contact area is small, so that can contact
Position generates biggish pressure and 23 top of annular support flange is deformed and more airtight 90 bottom surface periphery of fitting wafer, because
The annular support flange 23 of this wafer vacuum sucker 20 well can airtightly contact 90 lower surface of wafer and
It avoids generating gap between the wafer 90 and the annular support flange 23, it is thus possible in the wafer mounting apparatus 1
The wafer 90 and the carrier 80 are firmly adsorbed when exporting pull of vacuum, it is unexpected from institute to avoid implementing wafer 90 when solution bonding
Wafer mounting apparatus 1 is stated to fall off.Especially when 90 bottom surface of wafer has figure or the wafer 90 is thin wafer, warpage
When wafer or the wafer of uneven surface, the wafer vacuum sucker 20 only contacts the crystalline substance with the annular support flange 23
90 bottom surface peripheries of circle can effectively avoid the wafer 90 and loosen from the wafer vacuum sucker 20.
2. since the wafer vacuum sucker 20 only contacts the 90 bottom surface periphery of wafer with the annular support flange 23,
Rather than come into contact in a large area 90 bottom surface of wafer, the space of the vacuum tank 200 allow 90 bottom surface of wafer vacantly without with appoint
What object contact, therefore can avoid the problem of 90 bottom surface of wafer is surprisingly scratched or wounds by object and damages.
3. the thimble 45 can assist the vacuum tank 200 that the wafer 90 is removed to the wafer vacuum sucker 20, with benefit
The wafer 90 carries out follow-up process, and the Elastic Contact liner 451 of the thimble 45 can contact the wafer 90 simultaneously
Avoid damage to the wafer 90.
