Wet Chemical Process

Semiconductor Manufacturing – Wet Chemical Process Electro or Electroless Chemical Deposition Despite the fact that this is a smaller division of the semiconductor chip manufacturing industry, it still plays a crucial role. Wet chemical processes are used in etching, cleaning, and other stages in chip manufacturing. Wafers can be cleaned and rinsed after the first wafer preparation. In this stage, […]

Plasma Process

Semiconductor Manufacturing – Plasma Process The plasma process is one of the most hostile for elastomers, especially those vulnerable to chemicals and/or close to the substrate or the wafer. The most hostile plasma processes for elastomers include oxygen resist strip and radical based plasmas (such as remote NF3) and chamber cleans using remote plasma sources (RPS). Every seal, especially one […]

Semiconductor Material Grades

Semiconductor Material Grades

Material Grades used in Semiconductor Manufacturing What are the Semiconductor Material Grades? Performance requirements vary based on elastomer location in the process. The advantages of using our elastomer materials include decreased cost of ownership, extended tool Preventative Maintenance (PM) cycles, lower process defects, decreased particle origination and maximised device performance. Below is the table with our recommended material grades (Other […]

What is the difference between Teflon and PTFE?

Teflon vs PTFE

Teflon™ vs PTFE The sealing industry is full of trade names, technical phrases, and acronyms, which makes it hard to know what is what. In this learning journal, we will explain what Teflon™ and PTFE are, and also the differences. PTFE – what is it? PTFE is a carbon and fluorine synthetic polymer – Polytetrafluoroethylene. It is obtained from Tetrafluoroethylene […]

Rubber Compound – what is it?

what is rubber compound

What is a Rubber Compound? There is a misunderstanding that an elastomer compound is made out of one ingredient and that it is the same for every different type of polymer. The fact is that a rubber compound can be a combination of 3 to 15 various elements and thousands of different formations. Standard elastomer composition based on parts per […]

Outgassing

How to overcome the consequences of Outgassing Outgassing is defined as “the release of a gas that was dissolved, trapped, frozen, absorbed or adsorbed in some materials’’. Parts of rubber formulation, decomposition products of the ingredients or other gasses trapped in the polymer composition during the moulding process can turn unstable and be released under vacuum conditions. Visual Indications and […]

Shore A Hardness

What is a Shore A Hardness and why is it important? What is a Shore durometer? The Shore durometer is an instrument used for measuring the material’s hardness, generally rubbers, elastomers, and polymers. The Shore A hardness measurement is called ‘’durometer’’. Tests are carried out on cured rubber according to ASTM D2240, and on a complete O Ring according to […]
