In the semiconductor industry with the best semiconductor company, two of the many applications that need specialized equipment to deal with corrosive liquids or gases are cleaning and wet etching. These are only two of the many different tasks that fall into this category. There are a great number of other applications in this sector of the economy that have the same prerequisite. For these treatments, you will need water of exceptionally high purity as well as solvents that have a high level of chemical aggressivity.
Chip manufacturers and pcb manufacturing are obligate to maintain a high level of control over the fluids used in the manufacturing process. A pressure transducer needs to have a high degree of precision, corrosion resistance, and the ability to prevent any metal ions from leaking out. When it comes to delivering an exact reading of the pressure that is present throughout the manufacturing process of semiconductors, only the most advanced machinery is capable of doing so.
Fluoropolymer is a good choice for usage in the semiconductor sector since it is resistant to contamination throughout the production process. Because of this, they decided to create their new ZL91 and ZL92 pressure transducers out of this material.
The possible applications of these transducers within the semiconductor sector will be research at length in the upcoming investigation.
Featured considerations –
Because of their chemical compatibility as well as their low metal ion elution, these transducers are your best bet for maintaining a clean process. They also have a low metal ion elution.
The ZL91 and ZL92 both have designs that are at the cutting edge of technology, which makes it simpler for the semiconductor industry, which is now struggling, to fulfill the rising demand of consumers for semiconductor wafers and other components.
Materials –
If you are working with water that has been deionize or otherwise ultra-purified. The ZL91 pressure transducer is the instrument that you should use. Fluoropolymer (PTFE/PFA) is use in the construction of the wetted portions of this device. Which helps to reduce the amount of metal ion elution to the greatest extent that is practically possible. Because of its diminutive size, there is less danger of contamination. Which helps to guarantee that the process fluid will continue to be free of debris.
A ZL92 pressure transducer is an excellent option for use in corrosive gases and fluids hydrofluoric acid or other aggressive acids. Which are required for the production of many semiconductors. This is because the transducer can withstand the high levels of corrosion that are present in these environments. The lifespan of the transducer can be increase by incorporating a secondary isolation diaphragm and vent design. This design guards the ceramic sensing element against exposure to corrosive gases and liquids. The improved precision of the transducer is also due, in part, to the design of the device.
- ZL91:
- Conditions of Pressure:

- Sizes available for tube connections are 1/4 in., 3/8 in., and 1/2 in.
- Precision at 23 degrees Celsius (73 degrees Fahrenheit) is 1.0% of the span.
- Linearity, hysteresis, and repeatability are all aspects of accuracy.
- Domains of Use and Production Industries
These customized transducers are ideal for situations when regular stainless steel cannot be use due to incompatibility, problems, or cost. Use them in the following fields and endeavors with their highest recommendation:
- ZL91:
- Storage for Deionized or Ultrapure Water
- Machines for making deionized or ultrapure water
- Wet stations ZL92 for cleaning semiconductors and Flat Panel Displays (FPDs)
- Equipment for cleaning semiconductor chips
- Tools for maintaining LCD monitors (FPD)
- Processes that use liquids for etching
- Dry Stops
- The logistics involved in the supply of chemicals Arguments in support of and opposition to –
Both the ZL91 and the ZL92 are outstanding in a multitude of respects. When it comes to connecting these transducers to your system or process. You can choose from a wide selection of compression fittings and tube stub unions.
The ZL92 has many of the same advantages as its predecessor, the ZL91. However, it also includes a patent design that was develop by Nagano Keiki, which is the parent company. This design was develop to protect the sensing element from gases that are produce in applications that involve acid or corrosion. The ZL92 is shielded from the formation of a gas buildup inside the housing by the incorporation of both an air gap and a vent into the structure’s blueprint.
Although stainless steel is a common material for the fabrication of transducers. It is not necessarily a good fit for the uses describe here. Despite the material’s prohibitively expensive cost, Hastelloy does have use in certain settings. As a consequence of this, the ZL91 and ZL92 are the best low-cost solutions for applications these.
Wrap-Up –
The ZL91 and ZL92 pressure transducers are ideally suite for use in semiconductor applications. Where medium purity and/or corrosion resistance are of the utmost importance. As a consequence of this, you may have peace of mind knowing that the sensor you end up with will be reliable and long-lasting for the application in question.
Viewing the data sheets for the ZL91 and ZL92 will allow you to acquire additional knowledge regarding both models.
The learning materials that provide for its pressure transducer products include downloaded instructions, recorded webinars, and white papers, to name just a few of the options.
