Embodiment Construction

[0017] In the following detailed description, reference is made to the accompanying drawings which form a part hereof and which show by way of illustration specific embodiments in which the invention may be practiced. In this regard, directional terms such as "top", "bottom", "front", "rear", "front row", "trailing" etc. are used with reference to the orientation of the figure(s) described. Because components of an embodiment may be arranged in many different orientations, directional terminology is used for descriptive purposes and is by no means limiting. It is to be understood that other embodiments may be utilized and structural or logical changes may be made without departing from the scope of the present invention. The following detailed description is therefore not in a limiting sense, and the scope of the invention is defined by the appended claims. The described embodiments use specific language, which should not be construed as limiting the scope of the appending cl...

Abstract

A transformer device includes a glass substrate having a first side and a second side arranged opposite the first side. A first recess is formed at the first side of the glass substrate. A second recess is formed at the second side of the glass substrate. The first and second recesses are arranged opposite to each other. A first coil is arranged in the first recess and a second coil is arranged in the second recess.

Description

technical field [0001] Embodiments described herein relate to transformer devices, and in particular, to transformer devices integrated into glass substrates, coreless transformers, transformers with ferromagnetic cores, and methods of manufacturing the same. Background technique [0002] Inductors and transformers are used for signal processing, such as processing of gate signals for power devices. In many applications, especially high power applications, the primary and secondary windings of a transformer may operate at different voltages. Such transformers require reliable electrical insulation between primary and secondary windings to prevent electrical breakdown and failure of power devices. For example, a transformer may be used to directly couple a low voltage control unit for controlling a high voltage device with a high voltage device. Other options for coupling low voltage and high voltage devices are fiber optic devices or integrated circuits on SOI technology. ...
