BN Ceramics for PVD ALD and CVD Systems

Talking about the deposition techniques we have to mention Physical Vapor Deposition (PVD), Atomic Layer Deposition ( ALD) and Chemical Vapor Deposition (CVD) , which are fundamental in manufacturing high-precision components for semiconductors, electronics, aerospace industries even more. The versatility and properties of Boron Nitride (BN) ceramics make them become crucial components in PVD, ALD and CVD systems. Here I like to talk about the role of BN ceramics in these systems.

Boron Nitride ceramics are composed of boron and nitrogen atoms arranged in a lattice structure. They can exist in hexagonal (HBN), which is the most commonly used form due to its similarity to graphite, making it an excellent lubricant and insulator. Cubic BN, on the other hand, is known for its hardness, approaching that of diamond.

PVD systems are used to deposit thin films through the physical vaporization of material. BN ceramics play a vital role in PVD systems primarily due to their low thermal expansion, chemical resistance, and outstanding electrical insulation.

Low Thermal Expansion: In PVD systems, high temperatures are often required to vaporize materials. BN ceramics shows outstanding thermal stability, allowing them to withstand these high temperatures max about 1800 degree in high vacuum and 2100 degree in in active gas environment without degradation. This property is particularly valuable in maintaining the integrity of the deposition chamber and other components exposed to extreme conditions.

Chemical Resistance: The reactive nature of certain PVD processes can lead to chemical interactions with chamber components. BN ceramics are highly resistant to extreme corrosion and wear, guaranteeing the deposition system remains uncontaminated and operational for longer periods.

Electrical Insulation: BN ceramics is an excellent electrical insulation. It can prevent unneeded electrical discharges during the PVD process. This insulation helps maintain the accuracy and consistency of the deposition process.

BN material application – ultra high temperature plasma technology

This paper, which focuses on plasma technology and waste treatment, covers the field of environmental protection and a brief introduction to related ceramic materials.

With the growing population as well as the economic development makes the production of solid waste increase rapidly.

Therefore, how to deal with these wastes into useful materials is a major project in favor of human development.

Numerous researchers have devoted themselves to the in-depth study of environmentally friendly solid waste treatment technologies, and have developed a series of mature technological ideas, such as photochemical oxidation technology, pyrolysis technology and thermal plasma gasification technology, etc. Among them, thermal plasma can be used for the treatment of solid wastes. Among them, thermal plasma treatment of solid waste has the advantages of high temperature (103-104 K), high enthalpy, high reactivity, good controllability, etc., which opens up a new way for the harmlessness, minimization and resource treatment of solid waste.

Plasma is the fourth state of matter consisting of electrons, ions and neutral particles, and in the treatment of solid waste, the treatment of solid waste utilizes the properties of high temperature, high energy and high enthalpy of plasma. Plasma torch is one of the energy sources to make the waste gasification, the discharge between the electrodes will gas medium ionization, resulting in a high-temperature arc, high-temperature arc heating flow through the gaseous medium, thus generating a high temperature, ionization and conductivity of the plasma, the plasma flame temperature is generally in the 4,000-7,000 ℃, the highest up to tens of thousands of degrees, which for the pyrolysis of solid wastes into simple atoms This provides the energy required for the pyrolysis of solid waste into simple atoms. At high temperatures, the inorganic components of solid waste melt and solidify through rapid cooling to form glass, which can be used as building materials. The organic components are decomposed into syngas (the main components are CO and H2), which can be burned directly or used as a high-quality fuel and in the chemical synthesis industry. During the gasification process, the plasma heats up the syngas to a high temperature of 1200-1300 ℃, which can completely decompose the complex organic substances into small, simple molecules and avoid the production of toxic substances such as dioxins and furans. The production of toxic substances such as dioxins and furans is avoided.

One of the ceramic materials involved is BN, which is resistant to high temperatures and corrosion, and is currently used in ultra-high-temperature plasma gasification technology, where BN is used in the plasma torch.

Involving the issue of technical confidentiality, this will not be elaborated in detail.
However, it can be seen that BN can be used in plasma technology, in the treatment of wastewater, waste and other environmental protection areas.

Vacuum brazing of ceramics and metals

The general process of brazing ceramics and metals can be divided into seven processes: surface cleaning, paste coating, ceramic surface metallization, nickel plating, brazing and post-weld inspection.

Surface cleaning is to remove oil, sweat and oxide film on the surface of the base material. Metal parts and brazing materials are first degreased, then pickled or alkaline washed to remove the oxide film, rinsed with running water and dried. Parts with high requirements should be heat treated in a vacuum furnace or hydrogen furnace (or ion bombardment method) at an appropriate temperature and time to purify the surface of the parts. After cleaning, the parts must not come into contact with oily objects or bare hands, and should immediately enter the next process or be placed in a dryer. They cannot be exposed to the air for a long time. Ceramic parts should be cleaned with acetone and ultrasound, then rinsed with running water, and finally boiled with deionized water twice, each time for 15 minutes.

Direct brazing

When brazing directly (active metal method), the surface of the ceramic and metal parts to be welded should be cleaned first, and then assembled. To avoid cracks in component materials due to different thermal expansion coefficients, a buffer layer (one or more metal sheets) can be rotated between welds. The brazing material should be sandwiched between the two welded parts as much as possible or placed in a position where the gap is filled with brazing material, and then brazing should be performed like ordinary vacuum brazing.

(1)When using Ag-Cu-Ti brazing material for direct brazing, vacuum brazing should be used. When the vacuum degree in the furnace reaches 2.7×10-3Pa, heating begins, and the temperature can be increased rapidly at this time; when the temperature approaches the melting point of the brazing material, the temperature should be increased slowly so that the temperature of each part of the weldment tends to be consistent; when the brazing material melts, the temperature is quickly increased to the brazing temperature, and the insulation time is 3 to 5 minutes; when cooling, the temperature should be slowly reduced before 700℃, and it can be naturally cooled with the furnace after 700℃.

(2)When directly brazing Ti-Cu active brazing material, the brazing material can be in the form of Cu foil plus Ti powder or Cu parts plus Ti foil, or Ti powder can be coated on the ceramic surface and then Cu foil. All metal parts must be vacuum degassed before brazing. The degassing temperature of oxygen-free copper is 750-800℃. Ti, Nb, Ta, etc. require degassing at 900℃ for 15min. At this time, the vacuum degree should not be less than 6.7×10-3Pa. During brazing, the components to be welded are assembled in the fixture and heated to 900-1120℃ in a vacuum furnace for 2-5min. During the entire brazing process, the vacuum degree must not be less than 6.7×10-3Pa.

(3)The brazing process of the Ti-Ni method is similar to that of the Ti-Cu method, and the brazing temperature is 900±10℃.

In addition to surface quality inspection, the welded parts after brazing should also be subjected to thermal shock and mechanical property inspections. The sealing parts used for vacuum devices must also be leak tested in accordance with relevant regulations.
