    摘要： A double electron layer tunneling device is presented. Electrons tunnel from a two dimensional emitter layer to a two dimensional tunneling layer and continue traveling to a collector at a lower voltage. The emitter layer is interrupted by an isolation etch, a depletion gate, or an ion implant to prevent electrons from traveling from the source along the emitter to the drain. The collector is similarly interrupted by a backgate, an isolation etch, or an ion implant. When the device is used as a transistor, a control gate is added to control the allowed energy states of the emitter layer. The tunnel gate may be recessed to change the operating range of the device and allow for integrated complementary devices. Methods of forming the device are also set forth, utilizing epoxy-bond and stop etch (EBASE), pre-growth implantation of the backgate or post-growth implantation.

    摘要： A class of epoxy bond and stop etch (EBASE) microelectronic fabrication techniques is disclosed. The essence of such techniques is to grow circuit components on top of a stop etch layer grown on a first substrate. The first substrate and a host substrate are then bonded together so that the circuit components are attached to the host substrate by the bonding agent. The first substrate is then removed, e.g., by a chemical or physical etching process to which the stop etch layer is resistant. EBASE fabrication methods allow access to regions of a device structure which are usually blocked by the presence of a substrate, and are of particular utility in the fabrication of ultrafast electronic and optoelectronic devices and circuits.

    摘要： An automated test system for testing devices being manufactured comprises an infrared communications link for free space communications between a host and a device under test. The communications link is asymmetric and instructions from the host are acknowledged by the device. The instructions cause the device to operate, and the output of the device is monitored, logged, and compared to acceptance criteria. The host can then generate calibration messages to the device, to change the device operating characteristics as appropriate. The communications link uses an unmodulated data stream together with asynchronous handshaking and a robust checksum algorithm to ensure accurate communication.

    摘要： Apparatus and methods are provided to control a device, such as a light emitting dermatologic or cosmetic treatment device, and ensure that the device is in contact with skin while also determining the pigmentation level of skin. One or more light sources contact the skin and one or more detectors measure spectral remission from the skin. The obtained remission measurements are compared with known skin spectral remission values, and calibration allows measurements of absolute remission to be converted to fractional remission values. Skin pigmentation levels are compared to known base-line levels to determine and control appropriate treatment parameters. A temperature sensor allows correction for temperature variations. The apparatus may or may not be incorporated into the treatment device.
