Fab Facility Components

Improve the safety of your fab facility with Mott high purity porous Penta® Nickel bulk filters and Mott Precision Flow Restrictors.

High pressure oxygen systems are susceptible to adiabatic compression ignition when materials that cannot withstand a high ignition energy, like Teflon, are used in the system. The result can be catastrophic. Mott Penta® Nickel porous metal filters operate at higher temperatures than plastic, Teflon or Stainless Steel, and act as a heat sink to quench any potential flame.

Mott Precision Flow Restrictors installed inside the gas containment systems (i.e., valve manifold box, tool isolation box, and gas cabinet) limit the gas flow in a catastrophic event. They also reduce the needed air replacement flow rate in these vented containment systems which translates into smaller vent piping and therefore lower construction costs.

What are fabs?

Fabs, short for “fabrication plants,” are specialized facilities dedicated to the manufacturing of semiconductor devices, such as integrated circuits (ICs). Within these plants, silicon wafers undergo intricate processes, including doping, ion implantation, and etching, to transform into chips. Given the precision required in these processes, maintaining the utmost purity of gases and chemicals is essential. Mott Corporation plays a pivotal role by offering advanced filtration and gas delivery solutions to meet the high standards of purity in fabs.

FAQs: Fab Facility Components

Q: What components does Mott offer to improve the safety of a fab facility?

A: Mott provides high purity porous Penta® Nickel bulk filters and Precision Flow Restrictors to enhance the safety and efficiency of fab facilities.

Q: Why are Mott’s Penta® Nickel porous metal filters essential for a fab facility?

A: Mott’s Penta® Nickel porous metal filters operate at higher temperatures than materials like plastic, Teflon, or Stainless Steel. They act as a heat sink, quenching any potential flame, making them especially crucial for high-pressure oxygen systems in fab facilities where adiabatic compression ignition risks exist.

Q: How do Mott Precision Flow Restrictors benefit gas containment systems in a fab facility?

A: Mott Precision Flow Restrictors, when installed inside gas containment systems such as valve manifold boxes, tool isolation boxes, and gas cabinets, limit gas flow during catastrophic events. They also reduce the required air replacement flow rate in vented containment systems, leading to smaller vent piping and, consequently, lower construction costs. Porous metal is an ideal media for flow control because it provides consistent, laminar flow even in the most challenging process conditions. Compared to flow orifices, porous metal does not clog or exhibit turbulent flow issues because the gas passes through thousands of tiny pores rather than one flow channel.

Q: How do Mott’s solutions contribute to cost savings in a fab facility?

A: Mott’s solutions are designed with the specific goal of improving performance and reducing cost of ownership for our customers, across our portfolio of products:

By reducing the needed air flow rate in vented containment systems, Mott’s Precision Flow Restrictors allow for smaller vent piping, translating into lower construction costs for the fab facility. Our porous metal restrictors prevent surges in gas lines from contaminating downstream processes which reduces cost and downtime.

Organic Free Diffusers
Diffusers used in vacuum chambers are positioned very close to the wafer that is being processed. Due to proximity to the wafer, purity is critical to ensure optimal yield and prevent downtime for tool maintenance. Mott’s organic free solutions eliminate the potential for wafer contamination, thereby increasing yield and reducing downtime.

Sintered Fiber Filters
Mott’s sintered fiber filters, including point of use and bulk formats, provide customers with the lowest pressure drop in the market, 6X lower than sintered powder filters. Lower differential pressure variability from part to part allows for tighter system control in the semiconductor fab. Mott’s sintered fiber filters have 3-5 times lower dry-down time compared to PTFE filters, which reduces downtime for customers. Additionally, there is no fire risk compared to Teflon-based filter solutions.
