KYUSHU DENTSU CO., LTD.
Dry etching processing technology with high crystal frequency
Manufacturing crystal devices such as quartz resonator, crystal filter/oscillator. We developed the dry etching processing technology (plasma etching) to prevent noise of high frequency circuit, which is ideal for high frequency crystal products. We are currently involved with silicone/wafer polishing and processing.
[Product description] Speed regarding processing communication and circuits has improved, while crystal clock frequency used as the basic signal requires high frequency and low noise. Fundamental oscillation on an internal quartz oscillator is required to lower the noise on high frequency circuits. Our dry etching processing technology (plasma etching) is the most appropriate. We provide new services and products to our clients with this technology. [Authorization/Certification] Acquired ISO14001 and ISO 9001. [Intellectual property] Crystal etching technology (patent #3492933)
