    • The fabrication of bipolar junction transistors in silicon-on-sapphire (SOS) relies upon the laser-assisted dopant activation in SOS. A patterned 100% aluminum mask whose function is to reflect laser light from regions where melting of the silicon is undesirable is provided on an SOS wafer to be processed. The wafer is placed within a wafer carrier that is evacuated and backfilled with an inert atmosphere and that is provided with a window transparent to the wavelength of the laser beam to allow illumination of the masked wafer when the carrier is inserted into a laser processing system. A pulsed laser (typically an excimer laser) beam is appropriately shaped and homogenized and one or more pulses are directed onto the wafer. The laser beam pulse energy and pulse duration are set to obtain the optimal fluence impinging on the wafer in order to achieve the desired melt duration and corresponding junction depth. Care must be taken since activation and rapid dopant redistribution occurs when the laser fluence is above the melt threshold and below the ablation threshold. Thus, bipolar junction transistors in SOS utilize a pulsed laser activation of ion implanted dopant atoms. Appropriate masking and pulsed laser illumination assures the electrical activation of the dopant without allowing undesirable diffusion either vertically along crystallographic defects (diffusion pipes) or laterally.
    • 硅蓝宝石(SOS)中双极结晶体管的制造依赖于SOS中激光辅助的掺杂剂激活。 在要处理的SOS晶片上设置图案化的100%铝掩模,其功能是反射来自硅熔化区域的激光。 将晶片放置在被惰性气氛中抽真空并回填的晶片载体中,并且其具有对激光束的波长透明的窗口,以允许当载体插入激光加工系统时照射被屏蔽的晶片。 脉冲激光(通常是准分子激光器)光束被适当地成形并均匀化,并且一个或多个脉冲被引导到晶片上。 设置激光束脉冲能量和脉冲持续时间以获得撞击晶片的最佳注量,以获得所需的熔融持续时间和对应的结深度。 必须小心,因为当激光能量密度高于熔融阈值并低于消融阈值时,激活和快速掺杂剂再分配发生。 因此,SOS中的双极结晶体管利用离子注入掺杂原子的脉冲激光激活。 合适的掩蔽和脉冲激光照射确保掺杂剂的电活化,而不会沿着结晶缺陷(扩散管)或横向垂直地不期望地扩散。

    • The present invention provides systems and methods for simultaneous, parallel and/or rapid serial testing of material parameters or other parameters of the result of a process. The testing is typically used for screening different methods or materials to select those methods or materials with desired properties. A reactor structure used to form the materials may consist of an array of small isolated reaction chambers that overlie the substrate so that the substrate forms a bottom surface of each isolated reaction chamber. Test structures are formed on the substrate, where the location of each test structure corresponds to an isolated reaction chamber area of the reaction structure. Test structures are used to measure certain parameters, such as by probing contact pads for each test structure, or such testing may be performed in-situ during processing.

    • An improved voltage contrast test structure is disclosed. In general terms, the test structure can be fabricated in a single photolithography step or with a single reticle or mask. The test structure includes substructures which are designed to have a particular voltage potential pattern during a voltage contrast inspection. For example, when an electron beam is scanned across the test structure, an expected pattern of intensities are produced and imaged as a result of the expected voltage potentials of the test structure. However, when there is an unexpected pattern of voltage potentials present during the voltage contrast inspection, this indicates that a defect is present within the test structure. To produce different voltage potentials, a first set of substructures are coupled to a relatively large conductive structure, such as a large conductive pad, so that the first set of substructures charges more slowly than a second set of substructures that are not coupled to the relatively large conductive structure. Mechanisms for fabricating such a test structure are also disclosed. Additionally, searching mechanisms for quickly locating defects within such a test structure, as well as other types of voltage contrast structures, during a voltage contrast inspection are also provided.

    • A method or process of crystallizing and doping amorphous silicon (a-Si) on a low-temperature plastic substrate using a short pulsed high energy source in a selected environment, without heat propagation and build-up in the substrate. The pulsed energy processing of the a-Si in a selected environment, such as BF3 and PF5, will form a doped micro-crystalline or poly-crystalline silicon (pc-Si) region or junction point with improved mobilities, lifetimes and drift and diffusion lengths and with reduced resistivity. The advantage of this method or process is that it provides for high energy materials processing on low cost, low temperature, transparent plastic substrates. Using pulsed laser processing a high (>900.degree. C.), localized processing temperature can be achieved in thin films, with little accompanying temperature rise in the substrate, since substrate temperatures do not exceed 180.degree. C. for more than a few microseconds. This method enables use of plastics incapable of withstanding sustained processing temperatures (higher than 180.degree. C.) but which are much lower cost, have high tolerance to ultraviolet light, have high strength and good transparency, compared to higher temperature plastics such as polyimide.

    • Disclosed are mechanisms are provided for determining whether a particular integrated circuit (IC) pattern is susceptible to systematic failure, e.g., due to process fluctuations. In one embodiment, final resist patterns for such IC pattern are simulated using a sparse type simulator under various process settings. The sparse type simulator uses a model (e.g., a variable threshold resist model) for a particular photolithography process in which the IC pattern is to be fabricated. The model is generated from measurements taken from a plurality of simulated structures output from a rigorous type simulator. The simulated final resist patterns may then be analyzed to determine whether the corresponding IC pattern is susceptible to systematic failure. After an IC pattern which is susceptible to systematic failure has been found, a test structure may be fabricated from a plurality of IC patterns or cells. The cells of the test structure are arranged to have a particular pattern of voltage potential or brightness levels during a voltage contrast inspection. Mechanisms for quickly inspecting such test structures to thereby predict systematic yield of a product device containing patterns similar to the test structure cells are also disclosed.
