摘要: Methods, systems and apparatus are provided to apply a magnetic pre-conditioning to magnetic tunneling junction (MTJ) sensors and other micro-magnetic devices after fabrication but before testing, trimming or other subsequent processing. The fabricated sensor device is passed through a magnetic field that has a known direction and orientation relative to the device so that the device is placed into a known state prior to final testing and trimming. Various embodiments allow the field to be applied in situ by a permanent magnet or electromagnet as the devices are being processed by a conventional device handler or similar processing system.

摘要: A monolithic optoelectronic integrated circuit having an optical emission portion (18) and a drive portion (11, or 22 and 21). The drive portion is capable of accepting TTL and standard CMOS logic voltage levels. In a first embodiment, the monolithic optoelectronic integrated circuit (10) has a light emitting diode (18) driven by a dual gate FET (11). In a second embodiment, the monolithic optoelectronic integrated circuit (20) has a light emitting diode (18) driven by two FETs (22 and 21). In each embodiment (10 or 20), a gate (13 or 23) of the respective drive circuit accepts the TTL or standard CMOS logic voltage. Further, in each embodiment current limiting is accomplished by coupling a gate with the source of the FET (11 or 22). Thus, the output of the light emitting diode (18, 18) is controlled by an input signal to the drive circuit.

摘要: A vertical cavity surface emitting laser (VCSEL), comprised of a first 1/4 wave stack, an active layer and a second 1/4 wave stack, is integrated with a heterojunction bipolar transistor (HBT). The HBT is partially or fully positioned within either the first or the second 1/4 wave stack of the VCSEL. This method improves the planarity of the device, thus allowing for high performance devices to be fabricated. A top or bottom emitting device may be fabricated with the second 1/4 wave stack comprised of dielectric layers or semiconductor epitaxial layers.
