High purity disc type sputter targets for the Cressington 108 and 208 series Sputter Coaters

If you are looking for sputter targets for other brands of sputter coaters, please go to Disc or Foil Sputter Targets.

We now offer a 16% discount on new precious metal / noble SEM Sputter Targets in exchange for your old used target of same composition and dimensions. This exchange program simplifies your recycling or reclamation procedures and is available for Au, Au/Pd, Pt, Pt/Pd, Pd, Ag and Ir targets. Please select your desired replacement from the list below or, if not listed here, go to 60 - 38mm targets. Contact customer service for the exchange program details. Your new target will be shipped once we have received and checked your used target. This offer is not available for targets that have been bonded.

Useful Information for Selecting Target Material for Coating Non-conductive SEM Samples
Most SEM sputter coaters allow for using a choice of sputter target material to optimize the coating material for the sample and or application. Below are some useful tips for selecting sputter target metal to coat non-conductive samples. Please be aware that each sample is different and the coating quality is also affected by the interaction of sample material and target material. The metallization of the surface creates a thin conductive layer on a non-conductive sample An additional advantage is that most coating materials have a higher secondary electron (SE) yield as the sample material. Coating material with lower atomic numbers are more suitable for backscattered electron (BE) imaging of the sample. The information below is valid when using modern DC magnetron SEM sputter coaters.
Aluminum The sputter yield for Aluminum is very low and it oxidizes very quickly. Can only be sputtered in 208HRD. SDS (108KB PDF)
Gold Excellent and most widely used target material for standard SEM coating. Due to the low work function it is very efficient and when using an ultra-cool sputter coaters (such as the Cressington 108auto) there is virtually no heating of sensitive samples. Grain size is visible with high magnifications on modern SEMs. SDS (121KB PDF)
Gold/Palladium Has a higher work function than pure gold and hence lower sputtering rates. Au/Pd gives smaller grain size when evaporated, but in SEM sputter coaters the difference between Au and Au/Pd is small if practically visible at all. Less suitable for heat sensitive specimens and less suitable for EDS analysis due to two sets of peaks for the coating material.
Palladium Can be used as a lower cost alternative for low to medium magnification range. Lower SE signal. Alternative to avoid overlapping peaks as with Au when using EDS. SDS (118KB PDF)
Platinum Fine grain size; smaller than Au or Au/Pd. Higher work function than Au result in slower sputtering rates. Sensitive to "stress cracking" if oxygen is present. More expensive. High SE yield. SDS (119KB PDF)
Platinum/Palladium Similar grain size as Pt, but less sensitive to stress cracking. Good for FESEM. Best results are achieved in a high resolution coater such as the Cressington 208HR.
Silver Lower cost alternative for lower magnification range. Large grain size than Au. Suitable for table top SEMs. Lower SE yield than Au or Pt. Coating can oxidize if samples are not stored under vacuum. Alternative for special EDS work. SDS (92KB PDF)
Chromium Very fine grain size, useful for FESEM. Required high vacuum such as the Cressington 208HR coater to eliminate oxygen. Coating oxidizes and sample can only be stored in high vacuum. Image directly after coating. Excellent alternative for BE imaging of biological samples. Low sputtering rates. SDS (100KB PDF)
Iridium Very fine grain size. Excellent all-round coating material for FESEM samples. Requires high vacuum coater such as Cressington 208HR. Slower sputtering rates. SDS (92KB PDF)
Tungsten Alternative for Cr. Very fine grain size, but oxidizes very rapidly. Low sputtering rates
Titanium SDS (113KB PDF)
Tantalum SDS (121KB PDF)
Nickel Alternative for special EDS application, not ideal for SE imaging. Suitable for BE imaging. Very low sputtering rates. Coating oxidizes. SDS (161KB PDF)
Niobium SDS (125KB PDF)
Cobalt SDS (145KB PDF)
Copper Alternative for EDS applications. Suitable for medium/low magnifications, special EDS applications and BE imaging.
Aluminum SDS (108KB PDF)
