Quorum Technologies own the Polaron brand and in early 2006 they also purchased Emitech. ProSciTech is now the sole distributor for these three brands in Australasia, south of Singapore. In time, the instrument range may be rationalised, but at present all competing products of these brands are available and featured on our site. Some additional data may be available from www.quorumtech.com. |

Turbo versus diffusion pumped coating systems
High vacuum sputter coaters and vacuum evaporators commonly use an oil diffusion pump or a turbomolecular pump, both are backed by a two-stage rotary vane pump. A turbo pumped system should not be compared with a diffusion pumped system. Turbos are more expensive to purchase, but they require virtually no maintenance, don't allow oil vapour from the backing pump into the working chamber, use much less electric power and require no cooling water. Diffusion pumped systems should be phased out, because they are over their life time more expensive, and most of that expense is in energy. Diffusion pumps are environmentally undesirable. |

LARGE SAMPLE, HIGH RESOLUTION SPUTTER COATER - EMITECH K675X & K675XD
The K675X is a large chamber (300mm) fully automactic turbo pumped sputter coater that allows complete 200mm (8 inch) wafers can be coated in the K675X Sputtering Coater System. The base system with twin gear rotating sample stage gives a progressive elliptical rotation for even sputtering deposition. The K675X Coating System employs a triple magnetron target assembly which enhances the efficiency of the Sputtering process using low voltages, giving a thin and fine grain coating. There are three such target assemblies in the K675X, positioned to give coating over a large diameter which, together with a rotating sample table, ensures even depositions. This method allows standard targets to be utilised, and avoids the necessity of special large profile targets. The multi-target system is particularly useful in the semi-conductor wafer industry. It has a turbomolecular pump backed by a Rotary Vacuum Pump. The integrated instrument panel and plug-in electronics maximise 'up-time' and, with user-friendly designs, ensures satisfactory multi-user discipline. The sputtering parameters can be pre-set, including the gas bleed needle valve, which has electromagnetic valve back-up. The independent Vacuum Pump is controlled by the Instrument throughout the fully automatic coating cycle. It can be used to Sputter Coat targets such as Gold, and also targets that may need pre-cleaning, or the removal of oxide layers, such as Chromium. A shutter assembly is fitted as standard, which allows a Sputter Cleaning and the Sputter Cycle to be carried out while maintaining the vacuum. The K675XD version has two independently controlled sputtering heads and enables the deposition of two sequential coating materials without the need to break the vacuum. the K675XD is suitable for the samples up to 150mm (6 inch) in diameter. Features:
Advantages:
Note:Target thickness Most targets used are precious metals and usually they are only 0.1 or 0.2mm thick. From April 2007 the K575x and K675x target assemblies have been changed. If targets, like Al or Cr, thicker than 0.3mm are to be used with the new systems, appropriate spacers will be necessary under the dark space shield. Typically, a 1.5mm target will require a spacer ring (Part number A4117193). Specification of K675X Sputtering Coater System:

PELTIER COOLED HIGH RESOLUTION SPUTTER COATER - EMITECH K575X & K575XD
Note: K575X is discontinued and replaced by KQ150T-S. The K575X uses a 'Turbo' pump, backed by a Rotary Vacuum pump, the complete pumping sequence being under automatic control. The vacuum can be adjusted to suit conditions for Chromium or other oxidising metals, as well as Gold targets, and has a Timer to allow for a range of sputtering times. The Systems employs a Magnetron Target assembly, fitted with a 54mm Dia. quick change target. The sputter head is Peltier Cooled to give high performance, fine grain coatings (no water requirements needed). The Sputtering parameters can be pre-set including gas bleed needle valve, which has electromagnetic valve back up. A typical sputtering cycle will take 5 minutes. The K575XD (Dual Head), version of the above has two sputter heads. These are arranged such that for special coating applications, two sequential layers of a target material can be deposited without breaking the vacuum seal in this automatic unit. The K575X has Peltier cooling for very thick depositions normally associated with the K575XD (Dual) unit. It may be necessary to supplement with water cooling as required. Note:Target thickness Most targets used are precious metals and usually they are only 0.1 or 0.2mm thick. From April 2007 the K575X and K675X target assemblies have been changed. If targets, like Al or Cr, thicker than 0.3mm are to be used with the new systems, appropriate spacers will be necessary under the dark space shield. Typically, a 1.5mm target will require a spacer ring (Part number A4117193). SPECIFICATIONS:

LARGE SAMPLE SPUTTER COATER - EMITECH K650X & K650XT
The K650X is a digitally controlled large chamber sputter coater, ideally suited for SEM and other metal coating application. There are three magnetron target assemblies in the K650X, positioned to give coating over a large diameter which, together with a rotating sample table, ensures even depositions. This method allows standard targets to be utilised, and avoids the necessity of special large profiled targets. This triple sputter target system is particularly useful in the Semiconductor Wafer Industry. The magnetron target assemblies employed on this system enhance the efficiency of the process using low voltages, and giving a fine grain, cool sputtering, without the need to cool the target or the specimen stage. The three magnetron target assemblies in the K650X, which together with a rotating sample table enables even deposition over a large diameter of 200mm or 8 inches. The Instrument is fitted with three 60mm diameter and 0.1mm thick gold (or Customer choice) quick change targets, giving optimum consumable cost performance. The integrated instrument panel and plug-in electronics, maximise 'up-time' and, with user friendly designs, ensure satisfactory multi-user discipline. The sputtering parameters can be pre-set, including the gas bleed needle valve which has electromagnetic valve back-up which, together with automatic control, gives defined and repeatable film thickness depositions. The sputtering head is interlocked, and the system can easily accommodate the K250 Carbon Coating Attachment. The independent vacuum pump is controlled by the instrument throughout the fully automatic coating cycle. K650XT Turbo Unit is as detailed above but has turbo pumping at 60L/Second for a higher & cleaner vacuum. Features:

CARBON EVAPORATION
The use of carbon films on TEM specimen grids or as carbon coatings is common in electron microscopy. These films add little to the background signal and they have relatively good electrical conductivity. Thin films (5 nanometres) are used in TEM to stabilise some specimens. Thicker films (up to 30 nanometres) may be used for TEM support films and in SEM for X-Ray microanalysis. Commonly, a high vacuum evaporator with carbon rods is used to produce these coatings and this system is preferred for some applications. The use of carbon fibre, has allowed a flash evaporation technique, which is suitable for many general EM requirements. Quorum manufactures a range of evaporators to meet all needs. Carbon coatings produced in high vacuum have a finer grain and these are preferred for some TEM applications; flash evaporated carbon is used for conventional SEM and EDS /WDS. Carbon fibre must be used in the low vacuum, rotary vane pump only. For high vacuum system carbon/graphite rods are preferable.
