Abstract
A semiconductor device comprising at least one power device, at least one control element for controlling the power device(s), a plurality of first terminals connected to the power device(s), a plurality of second terminals connected to the control element(s), a support member having a heat sink disposed on a lower surface of the support member and the power device(s), control element(s), and first and second terminals arranged on the upper surface of the support member, and a package including the support member for sealing the devices and one end of the terminals such that first and second terminals protrude from different sides of the package. The arrangement allows a reduced size three-phase motor drive controller, a reduction in noise interference to the control element, and reduction in terminal pitch size.
