Leading supplier of high quality CMOS for RF device by SOS wafers
Two types of substrates: ESOS and BSOS
LAPIS Semiconductor Miyazaki manufactures SOS products using two types of substrates: ESOS that epi-silicon is generated on sapphire substrate,
BSOS that silicon substrate is bonded to sapphire substrate.
Since these substrates are transparent as shown in the above,
it is necessary to treat the back side so that process equipment can correctly recognize the presence of wafers and also implement electrostatic chuck.
High speed, high frequency characteristics, and low power consumption
SOS products are superior to silicon substrate products in terms of high speed, high frequency characteristics,
and low power consumption, and are applied to smartphone and mobile phone base station systems that transmit a large amount of information.
