Blanket Film Test Wafer Information

Blanket Film Test Wafer Applications
Blanket film test wafers are used in the development and maintenance of semiconductor fabrication processes. Semiconductor capital equipment manufacturers, for example, use blanket film test wafers to characterize fabrication processes.

Test wafers simulate the behavior of fab end user device wafers when processed on fabrication equipment. Since they are less expensive than patterned test wafers or device wafers, they provide a cost effective means performing process analysis on silicon wafer substrates.

Typically, blanket film test wafers include a series of one or more films fabricated on bare silicon wafers. Common films include oxides, nitrides, and different types of metals such as Tantalum, Copper and Aluminum. More exotic films include Nickel Silicide, Tungsten Silicide, Amorphous Carbon and other new materials.

Advantiv can supply 300mm low particle thermal oxide wafers. Typical LPD (Light Point Defect) levels are less than 30 particles at ≥0.136μm.

Some materials have specific trade names, such as Applied Materials Black Diamond™ and Black Diamond II™ low-K films, and Novellus Coral™ a low-K dielectric, carbon doped, oxide film processed on a Sequel Express™ CVD System.

CMP Characterization Wafers
Blanket copper wafers, blanket tungsten wafers and oxide wafers are used to support process development for CMP. Suppliers of CMP equipment and consumables use these wafers to determine the effectiveness of their products and processes. Blanket film test wafers can be used to characterize parameters such as polish rates, uniformity, dishing, erosion, and underpolish.

Advantiv offers a standard 200mm Blanket Copper test wafer with 3,000Å of thermal oxide, 250Å of Tantalum and 1,000Å of PVD Copper. Another standard blanket copper test wafer is available with electroplated copper. A standard 200mm electroplated blanket copper wafer is 3,000Å of thermal oxide with 250Å of Tantalum Nitride with 1,000Å of PVD Copper Seed and 15,000Å of electroplated copper, with an anneal.

Advantiv offers many configurations of blanket copper test wafers. Please contact us for more information on them.

Other Blanket Film Test wafers
Blanket film test wafers are also used for testing of etch rates and uniformities, measuring cleaning effectiveness, characterizing deposition uniformity and coverage and other evaluating process parameters. Blanket film test wafers are also used in the setup and calibration of equipment.

Advantiv part number 2TA-0109 is an example of a product used for setup of metrology equipment. It is a set of ten wafers, with Tantalum deposited over a pad oxide on bare 200mm silicon. There are two wafers of each of the following thicknesses:  200Å, 500Å 1,000Å 2,000Å and 3,000Å. The wafer set is also available with Tantalum Nitride, Tungsten, Ruthenium or Copper films.

Economically priced photoresist coating services are also available. Resist application can be provided for wafers ranging from 2 inch diameter to 300mm diameter.
