A semiconductor device formed of a flexible or rigid substrate (10) having a gate electrode (11), a source electrode (12), and a drain electrode (13) formed thereon and organic semiconductor material (14) disposed at least partially thereover. With appropriate selection of material, the gate electrode (11) will form a Schottky junction and an ohmic contact will form between the organic semiconductor material (14) and each of the source electrode (12) and drain electrode (13). In many of the embodiments, any of the above elements can be formed through contact or non-contact printing. Sizing of the resultant device can be readily scaled to suit various needs.
摘要:
The surface-mount device package comprises a pad located on a face of the surface-mount device, a solder bump bonded to the pad, and a terminal spaced radially apart from the pad. A terminal surrounds the pad in at least one common plane that bisects the pad and the terminal. An electrically resistive volume intervenes between the pad and the terminal. The pad is electrically coupled to the terminal through the resistive volume. The terminal, the pad, and the electrically resistive volume cooperate to form a passive component associated with at least one device interconnection. The passive component preferable comprises an integral resistor. The integral resistor serves to eliminate or at least substantially reduce electrical resonances and reflections that may otherwise degrade the signal integrity.

A microelectronic assembly, such as a surface-mount device or a ball-grid array (BGA) package, has one or more integral resistors. The integral resistors are incorporated into one or more of the microelectronic assembly's electrical leads or connections. The integral resistors preferably terminate in a solderable pad. For example, the BGA package may include an IC chip and interposer. A terminal is located on a surface of the IC chip, on a surface of the interposer, or on the surface of the substrate to which the BGA is mounted. An electrically-resistive material overlies the terminal and electrically couples the terminal to a bond pad, thereby defining an integral resistor. The integral resistors reduce electrical resonances and reflections that may otherwise degrade the signal integrity and reliability of the electrical system employing the device; hence, reduce or eliminate the requirement for discrete resistors for the microelectronic assembly.

A semiconductor structure for implementing optical beam switching includes a monocrystalline silicon substrate and an amorphous oxide material overlying the monocrystalline silicon substrate. A monocrystalline perovskite oxide material overlies the amorphous oxide material and a monocrystalline compound semiconductor material overlies the monocrystalline perovskite oxide material. An optical source component that is operable to transmit radiant energy is formed within the monocrystalline compound semiconductor layer. A diffraction grating including an electrochromic portion is optically coupled to the optical source component.
摘要:
A thick-film resistor and a process for forming the resistor to have accurate dimensions, thereby yielding a precise resistance value. The resistor generally includes an electrically resistive layer and a pair of terminals, a first of which is surrounded by the second terminal, so as to form a region therebetween that surrounds the first terminal and separates the first and second terminals. The terminals are preferably concentric, with the second terminal and the region therebetween being annular-shaped. The resistive layer electrically connects the first and second terminals to complete the resistor. Each of the terminals has a surface that is substantially parallel to an upper and/or lower surface of the resistive layer and contacts the resistive layer. The surfaces of the terminals may be embedded in the resistive layer by printing the resistive material over the terminals, or may contact the upper or lower surface of the resistive layer by locating the terminals above or below the resistive layer. In each of these embodiments, the terminals are not limited to having edge-to-edge contact with the resistive layer, such that the interfacial resistance therebetween is minimized.

A method and system for monitoring physiological parameters is useful for remote auscultation of the heart and lungs. The system includes an acoustic sensor (105) that has a stethoscopic cup (305). A membrane (325) is positioned adjacent to a first end of the stethoscopic cup (305), and an impedance matching element (335) is positioned adjacent to the membrane (325). The element (335) provides for acoustic impedance matching with a body such as a human torso. A microphone (315) is positioned near the other end of the stethoscopic cup (305) so as to detect sounds from the body. A signal-conditioning module (110) is then operatively connected to the acoustic sensor (105), and a wireless transceiver (115) is operatively connected to the signal-conditioning module (110). Auscultation can then occur at a remote facility that receives signals sent from the transceiver (115).
