Definitions
- the present invention relates to an apparatus for temporary semiconductor wafer bonding and debonding, and more particularly to an industrial-scale apparatus for temporary wafer bonding and debonding that comprises an automated thermal slide debonder.
- wafer thinning steps In some applications the wafers are thinned down to a thickness of less than 100 micrometers for the fabrication of integrated circuit (IC) devices. Thin wafers have the advantages of improved heat removal and better electrical operation of the fabricated IC devices. In one example, GaAs wafers are thinned down to 25 micrometers to fabricate power CMOS devices with improved heat removal. Wafer thinning also contributes to a reduction of the device capacitance and to an increase of its impedance, both of which result in an overall size reduction of the fabricated device. In other applications, wafer thinning is used for 3D-Integration bonding and for fabricating through wafer vias.
- IC integrated circuit
- Wafer thinning is usually performed via back-grinding and/or chemical mechanical polishing (CMP).
- CMP involves bringing the wafer surface into contact with a hard and flat rotating horizontal platter in the presence of a liquid slurry.
- the slurry usually contains abrasive powders, such as diamond or silicon carbide, along with chemical etchants such as ammonia, fluoride, or combinations thereof.
- the abrasives cause substrate thinning, while the etchants polish the substrate surface at the submicron level.
- the wafer is maintained in contact with the abrasives until a certain amount of substrate has been removed in order to achieve a targeted thickness.
- the wafer is usually held in place with a fixture that utilizes a vacuum chuck or some other means of mechanical attachment.
- a fixture that utilizes a vacuum chuck or some other means of mechanical attachment.
- An alternative to mechanical holding of the wafers during thinning involves attaching a first surface of the device wafer (i.e., wafer processed into a device) onto a carrier wafer and thinning down the exposed opposite device wafer surface. The bond between the carrier wafer and the device wafer is temporary and is removed (i.e., debonded) upon completion of the thinning processing steps.
- An improved apparatus for temporary wafer bonding and debonding 100 includes a temporary bonder 110, a wafer thinning station 120, a debonder 150, a cleaning module 170 and a taping module 180, as shown in FIG. 2 and FIG. 3.
- a secondary carrier is used for moving the thinned wafer from the debonder 120 to the cleaning 170 and taping 180 modules.
- the present invention eliminates the need for a secondary carrier by allowing a vacuum chuck 152 used in the thermal slide debonder 150 to remain with the thinned wafer 20 during the follow up processes steps of cleaning (52) and mounting onto a dicing tape (53).
- the thinned wafer 20 remains onto the vacuum chuck 152 and is moved with the vacuum chuck 152 into the various process stations, shown in FIG. 2. In another embodiment the thinned wafer 20 remains onto the vacuum chuck 152 and the various process stations 170, 180 move over the thinned wafer 20 to perform the various process steps, shown in FIG. 3.
- the invention features an apparatus for processing a temporary bonded wafer pair comprising a device wafer and a carrier wafer.
- the apparatus includes a debonder for debonding the device wafer from the carrier wafer after it has been thinned, a cleaning module for cleaning the debonded thinned device wafer, a taping module for applying a tape onto the debonded thinned device wafer and a vacuum chuck.
- the vacuum chuck is used in the debonder and includes means for holding the debonded thinned device wafer.
- the apparatus also includes means for moving the vacuum chuck with the debonded thinned device wafer into and out of the cleaning module and into and out of the taping module.
- the invention features an apparatus for processing a temporary bonded wafer pair comprising a device wafer and a carrier wafer.
- the apparatus includes a debonder for debonding the device wafer from the carrier wafer after it has been thinned, a cleaning module for cleaning the debonded thinned device wafer, a taping module, and a vacuum chuck used in the debonder and including means for holding the debonded thinned device wafer during debonding, cleaning and taping.
- the cleaning module includes means for moving over the debonded thinned wafer in the debonder for cleaning the debonded thinned wafer.
- the taping module includes means for moving over the debonded thinned wafer in the debonder for applying the tape onto the debonded thinned wafer.
- the debonder includes a top chuck assembly, a bottom chuck assembly, a static gantry supporting the top chuck assembly, an X-axis carriage drive supporting the bottom chuck assembly and an X-axis drive control configured to drive horizontally the X-axis carriage drive and the bottom chuck assembly from a loading zone to a process zone under the top chuck assembly and from the process zone back to the loading zone, and the bottom chuck assembly includes the vacuum chuck.

- temporary bond process 60a includes the following steps. First, device wafer 20 is coated with a protective coating 21 (62), the coating is then baked and chilled (63) and then the wafer is flipped (64). A carrier wafer 30 is coated with an adhesive layer 31 (65) and then the coating is baked and chilled (66).
- a dry adhesive film is laminated onto the carrier wafer, instead of coating an adhesive layer.
- the flipped device wafer 20 is aligned with the carrier wafer 30 so that the surface of the device wafer with the protective coating 20a is opposite to the surface of the carrier wafer with the adhesive layer 30a (67) and then the two wafers are bonded (68) in the temporary bonder module 210, shown in FIG. IB.
- the bond is a temporary bond between the protective layer 21 and the adhesive layer 31.
- no protective coating is applied onto the device wafer surface and the device wafer surface 20a is directly bonded with the adhesive layer 31.
- Examples of device wafers include GaAs wafers, silicon wafers, or any other semiconductor wafer that needs to be thinned down to less than 100 micrometers. These thin wafers are used in military and telecommunication applications for the fabrication of power amplifiers or other power devices where good heat removal and small power factor are desirable.
- the carrier wafer 30 is usually made of a non-contaminating material that is thermally matched with the device wafer, i.e., has the same coefficient of thermal expansion (CTE). Examples of carrier wafer materials include silicon, glass, sapphire, quartz or other semiconductor materials.
- the diameter of the carrier wafer 30 is usually the same as or slightly larger than the diameter of the device wafer 20, in order to support the device wafer edge and prevent cracking or chipping of the device wafer edge.
- the carrier wafer thickness is about 1000 micrometers and the total thickness variation (TTV) is 2-3 micrometers. Carrier wafers are recycled and reused after they are debonded from the device wafer.

- the chamber is evacuated and the temperature is raised to 200 °C for the formation of the bond between the protective coating layer 21 and the adhesive layer 31.
- the chamber is cooled and the fixture with the bonded wafer stack 10 is unloaded.
- the debond process 60b is a thermal slide debond process and includes the following steps, shown in FIG. 1A.
- the bonded wafer stack 10 is heated causing the adhesive layer 31 to become soft.
- the carrier wafer is then twisted around axis 169 and then slid off the wafer stack under controlled applied force and velocity (69).
- the separated device wafer 20 is then moved into the cleaning station 170 and cleaned (52) and then it is moved into the taping station 180 where it is mounted onto a dicing frame 25 (53).
- the thinned device wafer is thicker than about 100 micrometers usually no additional support is needed for moving the thinned wafer 20 from the thermal slide debonder 150 to the further processing stations 170, 180.
- a secondary support mechanism is required to prevent breaking or cracking of the thinned device wafer.
- the secondary support mechanism includes an electrostatic carrier or a carrier comprising a GelpakTM acrylic film on a specially constructed wafer. As was mentioned above, these secondary support mechanism add complications and cost to the process.
