Description of the Invention (!) A device for generating high voltage required for gas ionization, which is manufactured and installed with # 微 结构 化 的 结构 与 建筑 组When it comes to quality control, it is especially used in manufacturing wafers and microelectronic components and structural groups. During the manufacture and operation of microstructured technology products, electrostatic charging can cause damage. On the one hand, these structures are destroyed or damaged (EOS) by excessive electrical loads during uncontrolled discharge. If the components are operated under the conditions of a dedusting chamber, that is, they are sensitive to the damage of dust, the electrostatic charge can cause the deposition of many unwanted dust particles due to the Coulomb force (which will adsorb dust), especially during the production of semiconductor components. When manufacturing (Festplatte) and flat panel display (Flatpartel Display), optical coating, and photosensitive coating, the electrostatic charge is not desirable. For the generation of static electricity, all Everything is made of conductive material and properly grounded. But often this cannot be done comprehensively. Therefore, some of them need to be highly resistant to chemicals. They can only be made of fluoroplastics and have a high surface resistance. Or they must be made of insulating materials, and the products themselves are also highly insulated. However, they have to be harmed by charging. In this area, electrostatic charging can only be neutralized by using air to supply charge carriers. Air ionizers generate charge carriers (in the form of ions) carried by the air. This ionizer causes a gas discharge on the tip, sharp edge, or wire by applying a high voltage. In this gas discharge area (Townsend discharge), the air exists in an ionized state, each of which depends on the polarity of the high electricity. These ions of corresponding polarity are removed from the gas discharge area by the electric field force 3 (Please read the precautions on the back first) (Fill in this page again.)

Description of Invention (> ") It moves in the form of free ions (mainly nitrogen positive ions and oxygen negative ions), and is driven by the electric field or air flow to move through the air. This process has long been known and mentioned in the literature, and there is a series of patents on the implementation of this ionization (European patent EP 0448 929A1, German patent DE 3543618 Al, DE 3603947 A: 1, DE 3522881C1, US Patent US 4,477,263, International Patent PCT WO 96/02966, US Patent US 4,872,083, International Patent PCT WO 92/03863, US Patent US 5,153,811 'US 4,542,434' 4,117,332 '4,956,582' 4,809,127, 3,711,743, International Patent PCT WO 87/04873, etc.) . Modern dust room technology is gradually no longer using large hall-type dust rooms (where the manufacturing area and the personnel area are only slightly indistinguishable from each other), and is instead oriented to cabin-type machines and small production areas in the dust room technology ( SMIF Technik, 300mm Wafer Technolqgie, Minienvironments). BACKGROUND Ionizers require transformers or so-called waterfall (cascade) circuits to generate high voltages. These systems are bulky. These systems are not possible or difficult to put in small dust removal rooms (MinienviiOnments) due to the latter's narrowness. If the voltage supply system is integrated together, it will lose a lot of space, and if the voltage supply system is installed in the Minienvironments, it must be equipped with high-voltage cables, so there will be danger of high-voltage cables or necessary safety equipment. Therefore, there is a need for a compact, miniaturized ionization system with an integrated high voltage source. In addition, the US patent US 4620262 has published a high-temperature electrical energy converter, which can directly convert thermal energy into electrical energy without mechanical movement. 4 The paper size is in accordance with the Chinese Standard (CNS) A4 (210 X 297 mm).

Conversion of the description of the invention (>) path. Another disadvantage of the learner is that these traditional ionizers, due to their configuration, 'cause a wide (tens of centimeters) electric AC or DC field'. These electric fields are affected by the object to be neutralized This results in unwanted potential or charge movement. Therefore, an ionizer with a diffraction field as small as possible is required. The object of the present invention is to remove the disadvantages of the conventional background technology and provide a device 'for the manufacture, installation, and quality control of microstructured components and structural groups (particularly It is used to produce the high voltage required for gas ionization when manufacturing wafers and microelectronic components and structural groups. It can be directly used in or on a small or miniaturized ionization system with an integrated high-voltage power supply, and Only a small diffraction field is generated. According to the present invention, this object is achieved by using the feature points of the main item of the patent application scope. Further advantageous features of the present invention are found in the sub-item of the scope of patent application. To generate a local voltage, the pyroelectric effect is used on a crystal with a maximum pyroelectric coefficient.

Description of the invention (<) The valley device, so ignore the internal resistance and make an approaching automatic adjustment, which can often produce as many positive or negative ions. This kind of automatic adjustment and the traditional type that needs to cancel the generation of ions to avoid unipolar space charges are different. The Peltier element that is technically applicable is powered by several volts (0.2V ~ 10V), and the wires connected to it can Very suitable to meet the needs of modern dust room and unified. Using a pyroelectric single crystal with a size of 5mmX5mmX0.5nm (and preferably lithium tantalate) can generate a sufficient charge carrier to achieve the engineering neutralization time (< 20 seconds) available for electrostatic charge. In this way, a complete ionizer with a high voltage supply system and an electrode system can be built in a volume of one cubic centimeter. Because of its small size and small interference field, the present invention can be used to build Minienviroments. In the second figure, the entire ionization device of the first figure is buried in a dielectric (6) (Dielektnkum). The resulting unit is easy to clean, and it can also be used in aggressive media, which is advantageous for certain areas of semiconductor processing technology.
