Semiconductor

Especially in the semiconductor industry, high-purity crystals have long played a vital role. As the basis for separating devices (e.g., transistors and diodes), microelectronics (e.g., memories and ICs), and microsystem components (e.g., sensors and converters), the purity of the crystal and its lattice structure must reach the highest standards.

We provide the following products:

Czochralski Method

CGS was a spin off from Leybold-Heraeus Systems, focusing on the construction of crystal growing systems for the semiconductor industry. One of the methods that we use to grow crystalline ingot in the solar industry is called Czochalski method(CZ). In the CZ process, high-purity, polycrystalline silicon is put into the quartz crucible of a monocrystal growing system. Next, the process room is evacuated and the silicon is then melted down in an argon controlled atmosphere via resistive heating. After temperature stabilization of the melt (aprrox. 1420°C), a rotating monocrystalline seed crystal is dipped into the melt. As the result of a slight temperature decrease, crystallization of silicon material on the seed crystal is now initiated. As the seed is slowly pulled upwards, a cylindrical silicon moncrystal hanging on the seed crystal is then formed. The pulling speed and the temperature are regulated in such a way that a silicon moncrystal whose orientation and structure corresponds to the seed crystal can be grown with a constant diameter. Nowadays more and more companies start to use CZ method to grow mono ingot. Even though the process is quite complex and the cost of ownership is quite high, the conversion efficiency is much higher than the multi ingot. Also, the maturity of technology and the cell stability make the mono ingot become more competitive in the solar industry.

The diesel-type single crystal furnace we produce is developed for mass production needs, and the maximum diameter of the single crystal rods produced can reach 230mm.

Float Zone

 

Since the emergence of Float Zone technology in the late 1950s, Haldor Topsoe has been actively engaged in the research and production of Float Zone wafers. During the development process, many special equipments for Float Zone wafer production were developed. In 2004, the equipment division of Haldor Topsoe was acquired by the PVA TePla Group of Companies and is now merged into Crystal Growing Systems, CGS. Float Zone gets its name from its special growth method. Firstly, the high-density Poly Rod produced by a special process from the Siemens CVD furnace is fixed in the Float Zone crystal growth equipment, and then the Poly Rod is heated to the conductor state by indirect heating, and then the induction coil takes over the heating to make the Poly Rod partially Melt, and then prepare a single crystal seed crystal at the bottom.When the silicon soup touches the single crystal seed crystal, it will begin to crystallize. At the same time, the single crystal seed crystal will rotate downward so that there is enough space for the silicon soup. Condensed into a single crystal rod. The biggest difference between the Float Zone and the CZ method is that no crucible is needed in the process, and there is no graphite element in the thermal field, so the crystal oxygen content and carbon content can be minimized, and it is suitable for semiconductor high- power components.The biggest difference between the Float Zone and the CZ method is that no crucible is needed in the process, and there is no graphite element in the thermal field, so the crystal oxygen content and carbon content can be minimized, and it is suitable for semiconductor high-power components.The biggest difference between the Float Zone and the CZ method is that no crucible is needed in the process, and there is no graphite element in the thermal field, so the crystal oxygen content and carbon content can be minimized, and it is suitable for semiconductor high-power components.

SR 110 (Slim Rod Puller) is designed to produce silicon core rods in Siemens CVD reactors. The diameter of the rods is about 7-10mm, and the height can reach up to 2.5 meters.

The SR 110 is a very efficient model because it can produce two silicon core rods at the same time in one manufacturing process. Compared with the CZ method and cutting with a band saw or wire saw, it can avoid material loss. In addition, the machine is designed after thorough consideration, so it is very easy to use, and after the production of a set of silicon core rods, the next set can be produced immediately. This is due to the special valves in the reaction chamber and the upper receiving chamber. design. Depending on the diameter of the raw material rod and the length of the required silicon core rod, one raw material rod can produce 12 to 50 silicon core rods.

FZ-14M was born for testing needs. The principle of operation is to use the zone melting method to convert miniature polycrystalline silicon rods into single crystal silicon, and then put them into appropriate instruments to evaluate the quality and purity of the polycrystalline silicon materials. During the zone melting process, the polycrystalline rod is placed in an argon-filled environment to form a single crystal rod.

This single crystal rod will be analyzed by spectroscopic analysis for trace impurities such as boron, phosphorus, aluminum, arsenic, carbon and so on.

We can provide our customers with consultation and layout suggestions. In addition, we can provide training for the employees as well as supporting services according to your demand. Please find out a brief introduction below of our products:

Valves

Industrial valves are “control points“ in process technology. Beside the classical “ON/OFF“ control system, the exact dosage or another direction of flow is necessary in order to control the process in hand. The type of medium flowing, temperature and ambient conditions dictate the selection of a suitable valve. When the right selection has been made, a pneumatic or electric actuator rounds-off the valve to the effect that automation is carried through to completion. The advantage of automation lies in the fact that the process in the plant can be controlled more exactly and is in turn safer.

Actuators

Pneumatic actuators and electric actuators in plant construction apply to ON/OFF – as well as to positioning applications. They can be deployed in almost all types of pipework plant.Some examples include chemical products, foodstuffs, paper production as well as water and wastewater treatment. Our products have proved their worth over decades. Special applications are covered by our stainless steel actuators or special coatings.

Electric actuator

The electric actuator series have a wider range of services, and can be equipped with PLC, Internet, Bluetooth, Wi-Fi, etc., and can support mobile phone or tablet.

Besides, the DV series has been certified by DNV GL, and is suitable for ships, offshore units and light craft. In 2020, it won the French navy tug supply contract.

Accessories

This is the most comprehensive product group, finally enabling a custom-designed layout and control of automatic valves. The driving actuator for the valve has interfaces for positioner, limit switch boxes and override gear boxes as well as additional interfaces for solenoid valve and pressure booster. Throttles and silencers are equally useful for smooth and safe plant operation. Our sales staff will gladly listen to you and discuss the way towards a solution.Please contact us for more details.
