摘要:
An integrated circuit inductor and a substrate with doped regions are provided. The substrate may be a p-type substrate and the substrate may have n-type doped regions. The n-type doped regions may include n-type wells, deep n-type wells, and n+ regions. The n-type doped regions may be formed in a pattern of strips such as a triangular comb pattern of strips or a series of L-shaped strips. The strips may be oriented perpendicular to the spiral of the inductor. A positive bias voltage may be applied to the n-type doped regions to create a depleted region in the substrate between the n-type doped regions. The depleted region may increase the effective distance between the inductor and the substrate, minimizing undesired coupling effects between the inductor and the substrate and increasing the effectiveness of the inductor.

Aussparungen oder Vertiefungen (3) werden in der Oberseite eines Halbleiterkörpers (1) ausgeätzt und Sensorkomponenten (10) darin hergestellt, die etwa zur Hälfte versenkt sind. Elektronische Bauelemente (n,p + ,5,6,7) werden in dem restlichen Bereich der Oberseite des Halbleiterkörpers (1) hergestellt, wobei diese ggf. mit einer Schutzschicht (7) abgedeckt werden, falls die Aussparung oder Vertiefung erst nachträglich hergestellt wird.

Disclosed inventions are directed to advanced high-voltage switches with improved performance characteristics, increased reliability, and better compatibility with conventional gate drivers. The inventions disclosed herein implement a hybrid switch, comprising a high-voltage normally-on SiC VJFET, controlled via a low-voltage Si MOSFET in a cascode (Baliga-pair) configuration. The SiC VJFET and Si MOSFET are integrated monolithically at a wafer level, with the Si MOSFET fabricated on the Si layer that is directly adjacent to a dielectric layer on top of the SiC VJFET. Methods of making and operating these switches are also provided.

摘要:
In one implementation, a semiconductor package includes a patterned conductive carrier including a support segment (330a) having a partially etched recess (344,364). The semiconductor package also includes an integrated circuit (IC)(350) situated on the support segment (330a), and an electrical connector (360) coupling the IC (350) to the partially etched recess (344,364). In addition, the semiconductor package includes a packaging dielectric (370) formed over the patterned conductive carrier (330a) and the IC (350). The packaging dielectric interfaces (370) with and mechanically engages the partially etched recess (344,364) so as to prevent delamination of the electrical connector (360).
摘要:
Technology capable of improving reliability of a semiconductor device is provided. In the present invention, a gate pad GPj formed on a front surface of a semiconductor chip CHP1 is disposed so as to be closer to a source lead SL than to other leads (a drain lead DL and a gate lead GL). As a result, according to the present invention, a distance between the gate pad GPj and the source lead SL can be shortened, and thus a length of the wire Wgj for connecting the gate pad GPj and the source lead SL together can be shortened. Thus, according to the present invention, a parasitic inductance that is present in the wire Wgj can be sufficiently reduced.
