Samsung also said its net profit soared 89 percent year-on-year to reach 11 trillion won ($9.88 billion) - a trillion won higher than estimated by Yonhap Infomax. The chips unit posted 8 trillion won ($7.2 billion) in operating profit, or almost half the group's total.
While Mr Lee and Ms Park battle allegations of bribery and other charges, Samsung is thriving thanks to tiny microchips called DRAM and NAND memory chips, which are needed to store and process data in servers and mobile devices.
This strong demand did lead to Samsung paying higher component costs but there was still a large increase in the earnings of its mobile division thanks to the release of the new Galaxy S8 and S8+.

For the mobile business, revenue increased 11 percent to 29 trillion won but profit fell by 3 billion won to 4 trillion won. The rising use of vehicle connectivity and the "internet of things" is expected to drive still further demand for the chips that have helped Samsung move ahead, at least for now.
