摘要： Wide band gap semiconductor wafers with previously unattainable characteristics and the method of processing and producing the same are disclosed and claimed herein. Specifically, the application discloses and claims a method to process silicon carbide and other similar wide band gap semiconductors in a microgravity environment. The wafers are placed onto stackable containment systems that create an appropriate gap between each wafer to allow for homogeneous heating and processing. The resulting wide band gap semiconductors have unique molecular structures not attainable when wide band gap semiconductors with the identical chemical composition are produced in a standard 1 gravity environment.

摘要： A semiconductor device can comprise a contact material in substantially continuous contact with a contact region. In an embodiment the contact region may comprise an alloy comprising a wide band-gap material and a low melting point contact material. A wide band-gap material may comprise silicon carbide and a low melting point contact material may comprise aluminum. In another embodiment a substantially uniform ohmic contact may be formed between a contact material and a semiconductor material by annealing the contact at a temperature less than the melting point of the contact material. In an embodiment, the contact may be annealed for more than five hours.

摘要： A receiving system dynamically searches a communications band for transmissions of messages having the same nominal communications parameters, including the use of the same spreading code, but having potentially different specific frequencies and code-phases. The receiver samples the communications band at each code-phase of the spreading code over a span of down-converted transmission frequencies. When a message element is detected at a particular code-phase and frequency, it is forwarded to a demodulator that demodulates the message and sends it to its intended destination. This technique allows each transmitter to be independent of the receiver. In a preferred embodiment of this invention, a Fast M-Sequence Transform (a Walsh-Hadamard Transform) is used to determine the power level at multiple code-phases at a given frequency in parallel, thereby substantially reducing the time required to search for transmissions at each discrete code-phase.
摘要翻译：接收系统动态地搜索通信频带中具有相同标称通信参数的消息的传输，包括使用相同的扩展码，但具有潜在不同的特定频率和码相位。接收机在扩展码的每个代码阶段通过下变频传输频率的跨度对通信频带进行采样。当在特定码相和频率处检测到消息元素时，它被转发到解调器，解调器将其发送到其预定的目的地。这种技术允许每个发射机独立于接收机。在本发明的优选实施例中，使用快速M序列变换（沃尔什 - 哈达马夫变换）来以给定频率并行确定多个码相的功率电平，从而大大减少搜索传输所需的时间在每个离散代码阶段。
