BUSINESS

BGBM

LB Lusem's BGBM (Back Grinding Back Metal) technology is applied to power devices in all electronic circuits where batteries are used, such as Smartphone, Navigation, TV, Audio, Server power, etc., where MOSFET (Metal-Oxide Semiconductor Field Effect Transistor) products are used. /It is the technology that can be applied.
In order to realize customer satisfaction, the company has developed a turn-key business based on differentiated technology from the existing commercialized MOSFET PKG process. Realization is the vision of the business.

We have the best technology through re-establishment of process flow, and by securing wafer level 30~50um Full Grind technology, we realized low resistance and low heat conduction by reducing wafer thickness.
BSM (Back Side Metal), which is responding to the level of 30um, is also prepared to be modified and supplemented according to customer requests.

The power device of the electronic device battery applied with the company's superior technology increases the life time by reducing standby power, and provides a solution for customer satisfaction with the best product through a thorough inspection process.
In order to go one step further as a Best Partner, we are doing our best to continuously develop products based on the best products and L/T (Lead Time) reduction through Process Optimize.
