A company that supports digitalization behind the scenes


Semiconductors are always used in the latest technologies such as IoT (Internet of Things), 5G, cloud, AI, smartphones, and VR (virtual reality) .
Our high-frequency power supply is an indispensable product for equipment that manufactures semiconductors that play a role in accelerating digitalization.
Our technology is a company that supports the digitalization of society behind the scenes.

  1. 01.the study

    Our company is researching the possibilities of high frequencies every day.
    For example, we are actively researching the latest technologies, such as research into high-frequency power sources for power transmission used to charge electric vehicles,
    research into pulse technology to support µm and nm miniaturization technology,
    and research into high-efficiency high-frequency power amplifiers (SiC and GaN). We are incorporating technology.
    We will not be satisfied with the status quo and aim to be No. 1 in the high frequency field.

  2. 02.Design development/manufacturing

    We design and develop high frequency power supplies to meet customer needs.
    NRF's strength is that we listen thoroughly to our customers' requirements and work together with them to create products.
    By integrating everything from development to manufacturing, we can respond quickly and at low cost.
    Since we can customize even a single item, we are able to supply products that suit the customer's equipment.

  3. 03.consulting

    Our top priority is to ensure that the products we sell are used in our customers' equipment and contribute to society.
    For this reason, we provide thorough support for any problems that may occur after the products we sell are installed on equipment.
    We will respond flexibly to inquiries from customers by telephone, remote meetings, on-site support, etc.
    We will help you solve your problems based on our many years of experience.

What is high frequency power supply?

RF-Generator is also known as RF power supply (radio frequency generator), and is the origin of our company's name.

Generally refers to equipment that generates high-frequency current of 10kHz or higher.
In our case, it is possible to support from 80kHz to 1GHz.
In Japan, 13.56MHz is the most used frequency due to the international standard (ISM band).

What is the usage scene?

Semiconductor manufacturing equipment, LCD panel manufacturing equipment, solar cell manufacturing equipment, MEMS manufacturing equipment, DLC manufacturing equipment, plasma cleaning equipment, power transmission, drying/thawing, induction heating, metal and plastic welding/processing, accelerators, tables It is used for surface modification, cancer thermotherapy devices, etc.

Our high-frequency power supplies are often used in semiconductor manufacturing equipment (processes such as etching, CVD, PVD, and ashing).

case study

  1. 01Succeeded in controlling three frequencies with one matching box. Experiments that were previously impossible are now possible.

    We received an inquiry from a manufacturer of thin film forming equipment who wanted to control three different frequencies using three power supplies and one matching box for research and development purposes.
    Until then, there had been no experience of controlling three frequencies with one matching box, but it became possible to do so by installing a physical switching device inside.
    It has now become possible to conduct experiments that were previously impossible, and the end users seem to be happy with it.

  2. 02Implemented measures against high frequency noise that affects peripheral devices.

    A customer asked us to do something about high-frequency noise on their equipment, which was affecting peripheral equipment, so we implemented noise countermeasures.
    Upon investigation, we discovered that high-frequency noise was leaking out through the signal line, and solved the problem by installing a noise cut filter.

  3. 03Maximize alignment speed.

    We received a request to speed up Teplasma's ignition process, and by taking the following measures, we were able to speed it up to the maximum possible speed.
    ① Perform calculations that do not depend on electric power to achieve the fastest response speed of the mechanical system.
    ② By setting the position of the variable element during RF-ON, unnecessary delay time until plasma ignition is eliminated.
