THIN FILM DEPOSITION

Target Bonding Services

Precision bonding and backing-plate solutions for sputtering targets used in research and production deposition systems.

ASSEMBLY SERVICES

Bonding selected for the whole target assembly

Basis Materials provides sputtering target bonding and backing-plate assembly services for metal, alloy, ceramic and compound targets. We review target material, geometry, backing-plate design, operating temperature, sputtering power and thermal-expansion behavior.

We support standard research targets as well as custom and production-scale assemblies. The bonding method, backing-plate material and assembly configuration are selected to match the customer's sputtering source and process requirements.

For your inquiry, distinguish the sputtering material from the complete assembly: specify whether you need a bare target, a target bonded to a backing plate, a separate backing plate, or a rotary target assembly. A product image does not confirm that a backing plate or bonding is included; the quoted configuration defines the supply scope.

01 / BONDING OPTIONS

Bonding Options

Each method is reviewed against the material system and operating conditions.

01

Indium Bonding

Indium provides a conductive, compliant bond layer that can help accommodate expansion differences between a target and backing plate. It is used for many metal and ceramic targets in research and production systems.

  • Strong heat and electrical transfer
  • Compliant bond layer
  • Backing plates can often be reused after debonding
02

Elastomer Bonding

A flexible interface can be useful for fragile or low-density targets, ceramic and compound materials, and assemblies with thermal-expansion mismatch. Suitability depends on the specific operating conditions.

  • Stress-accommodating interface
  • Low-temperature bonding process
  • Can suit applications beyond conventional indium temperature limits
03

Metallic Alloy / Solder Bonding

Alternative metallic bonding materials can be selected for custom assemblies according to target, backing plate and service conditions. Options may include indium-based alloys and compatible silver-based systems.

  • Conductive metallic interface
  • Material-specific solder selection
  • Engineering review of temperature and compatibility
04

Diffusion Bonding

For selected compatible material systems, a metallurgical bond may be possible without a conventional low-melting solder layer. This route requires engineering review of materials and process temperature.

  • Metallurgical interface
  • No conventional solder layer
  • Considered for selected high-power or specialized assemblies

02 / BACKING PLATES

Backing Plates and Custom Target Assemblies

We can supply complete bonded assemblies or evaluate customer-supplied targets and backing plates.

  • OFHC copper backing plates
  • Backing plates manufactured to drawing
  • Circular, rectangular and custom geometries
  • OEM-compatible configurations
  • Planar target assemblies
  • Rotary target assemblies where applicable
  • Multi-piece and tiled assemblies
  • Customer-supplied backing plate evaluation
  • Debonding and rebonding
  • Backing-plate reuse when condition permits

03 / ENGINEERING REVIEW

Bonding Selection for Your Process

The optimum method depends on more than target material alone. We review the assembly and deposition conditions before recommending a configuration.

  1. Target material
  2. Target dimensions and geometry
  3. Backing-plate design
  4. Sputtering power
  5. Operating temperature
  6. Thermal-expansion compatibility

04 / QUALITY & INSPECTION

Bond Integrity Matters

Consistent contact between target and backing plate supports heat transfer to the cathode cooling system. Inspection and documentation options are reviewed for each assembly and customer requirement.

  • Bond coverage inspection
  • Dimensional inspection
  • Alignment verification
  • Visual inspection
  • Bond-interface evaluation
  • Documentation on request

Before You Request a Bonded Target

Please specify the target, backing plate, and finished assembly separately. Include target-only thickness, plate thickness and mounting features, and the maximum assembled envelope defined by your cathode drawing.

Tell us whether you need new components or evaluation of a customer-supplied or previously used backing plate. Add the cathode model, intended power, cooling conditions, and any restrictions on bonding materials or interlayers.

Need help organizing the dimensions? See the bonded-target specification example.

Final dimensions, bonding method, inspection scope, and operating requirements are confirmed in the quotation.

Request a Bonded Target Assembly

Send your target material, dimensions, backing-plate drawing or sputtering-source information. We can review the assembly and recommend a bonding configuration.

Have a drawing? Email it to sales@basismaterials.com with the target material and your name.

Film mass estimation only. This tool does not determine target dimensions, target lifetime or bonding requirements.
