An integrated circuit for implementing a resistor network on a die of the integrated circuit. The integrated circuit includes a common conductor (302), which is disposed on a first side of the die and coupled to resistors (R1...R22) of the resistor network. The integrated circuit further includes a substantially conductive substrate through the die. There is further included a conductive back side contact coupled to the substantially conductive substrate, whereby the common conductor, the substantially substrate, and the conductive back side contact form a common conducting bus from the common conductor to the conductive back side contact through the die.

Es wird ein elektronisches Modul zum Einbau in einen Datenträger beschrieben, wobei das elektronische Modul einen auf einem Träger des Moduls angeordneten integrierten Schaltkreis aufweist, der leitend mit einer Spule für den berührungslosen Datenaustausch verbunden ist. Um derartige elektronische Module einfach herstellbar und kostengünstiger zu gestalten, wird beim erfindungsgemäßen Modul auf ein zusätzliches separates Substrat zur Aufnahme des integrierten Schaltkreises und der Spule gänzlich verzichtet.

This invention miniaturizes a package of a semiconductor device and simplifies a manufacturing procedure to reduce a manufacturing cost. A semiconductor wafer (30A) formed of a plurality of semiconductor chips (10A) formed with MEMS devices (11A) and wiring (13) thereof on front surface thereof and a cap arrayed wafer (40A) disposed with a plurality of sealing caps (20A) are attached to seal the MEMS devices (11A) in cavities (CV) between them. Then, a plurality of via-holes (13) is provided penetrating through the semiconductor wafer (30A) to form embedded electrodes (14) therein, and bump electrodes (15) are formed thereon. After this procedure, this structure is cut along scribe lines (L) to be divided into each of packages.

A three-dimensional micro-electromechanical (MEM) varactor is described wherein a movable beam (50) and fixed electrodes (51) are respectively fabricated on separate substrates coupled to each other. The movable beam with comb-drive electrodes are fabricated on the 'chip side' while the fixed bottom electrode is fabricated on a separated substrate 'carrier side'. Upon fabrication of the device on both surfaces of the substrate, the chip side device is diced and 'flipped over', aligned and joined to the 'carrier' substrate to form the final device. Comb-drive (fins) electrodes are used for actuation while the motion of the electrode provides changes in capacitance. Due to the constant driving forces involved, a large capacitance tuning range can be obtained. The three dimensional aspect of the device avails large surface area. When large aspect ratio features are provided, a lower actuation voltage can be used. Upon fabrication, the MEMS device is completely encapsulated, requiring no additional packaging of the device. Further, since alignment and bonding can be done on a wafer scale (wafer scale MEMS packaging), an improved device yield can be obtained at a lower cost.
