SEMICONDUCTOR DEVICE AND METHOD OF MANUFACTURING SAME

摘要

The invention relates to a semiconductor device (100) with a semiconductor body (10) comprising at least one semiconductor element (H) with an active area (A) and a coil (20) coupled to said element (H). The coil (20) and a further coil (21) jointly form a transformer (F). The semiconductor body (10) is secured to a carrier plate (30) which comprises an electrically insulating material and is covered with a conductor track (21). According to the invention, the further coil (21) is positioned on the carrier plate (30) and is formed by the conductor track (21) and electrically separated from the coil (20). In this way, a-device (100) is obtained which is easier to manufacture than the known device. Moreover, the communication between the element (H) and the outside world does not involve an electrical coupling and hence, for example, bonding wires, are not necessary. The invention is particularly advantageous for a (discrete) bipolar transistor, which can suitably be used for surface mounting. The invention further comprises an easy method of manufacturing a device (100) according to the invention.
