Latest Patents

One of Jong Hee Choi's latest patents is for a multi-chip package that eliminates the die pad. This design provides more room for elements within the package, achieving a balanced inner structure and preventing poor molding that could expose package elements. The upper chip is bonded to the top surface of a lower chip, with auxiliary leads from a lead frame stabilizing the chips. This configuration shortens wire lengths, reducing wire loop heights and minimizing the risk of exposure during transfer-molding. Additionally, the patent includes an auxiliary lead that supports the semiconductor chip, preventing tilting and shifting during the molding process.

Another significant patent involves an air conditioner equipped with a supplemental gas heater for the outdoor coil. This innovative air conditioning system features a compressor, indoor heat exchanger, expansion tube, and outdoor heat exchanger, all interconnected by refrigerant conduits. In cooling mode, the outdoor heat exchanger directs ambient air horizontally across heat exchange coils. In heating mode, heated air from an auxiliary gas-fired heater is conducted upward across the same coils. The outdoor heat exchanger is designed with movable blades to create both horizontal and vertical air flow passages, enhancing its functionality in varying conditions.
