    • The invention relates to an electromagnetic piezoelectric acoustic sensor (EMPAS). The sensor comprises a piezoelectric sensor plate spaced apart from an induced dynamic electromagnetic field, such as from an electromagnetic coil through which AC current flows. The electromagnetic field induces vibration in the sensor plate by fluctuating the aligned dipole moments of the piezoelectric material. Changes on the surface of the sensor plate can be detected by variation in resonance frequency of the sensor plate. The invention represents an improvement over conventional sensor methodologies in that no metallization of the sensor surface is required, and no permanent magnet is needed. The sensor may be used to detect absorption of molecules or biomolecular interactions between probe and target molecules.

    • A chuck for supporting a wafer and maintaining a constant background temperature across the wafer during laser thermal processing (LTP) is disclosed. The chuck includes a heat sink and a thermal mass in the form of a heater module. The heater module is in thermal communication with the heat sink, but is physically separated therefrom by a thermal insulator layer. The thermal insulator maintains a substantially constant power loss at least equal to the maximum power delivered by the laser, less that lost by radiation and convection. A top plate is arranged atop the heater module, supports the wafer to be processed, and provides a contamination barrier. The heater module is coupled to a power supply that is adapted to provide varying amounts of power to the heater module to maintain the heater module at the constant background temperature even when the wafer experiences a spatially and temporally varying heat load from an LTP laser beam. Thus, heat from the laser is transferred from the wafer to the heat sink via the heater module and the insulator layer. In the absence of any laser heating, heat is also transferred from the heater module to the wafer as needed to maintain the constant background temperature.
    • 公开了一种用于在激光热处理(LTP)期间支撑晶片并在晶片上保持恒定的背景温度的卡盘。 卡盘包括散热器和加热器模块形式的热质量。 加热器模块与散热器热连通,但是通过绝热层在物理上与其分离。 热绝缘体保持至少等于由激光器传递的最大功率的基本恒定的功率损耗,而不是由辐射和对流损失。 顶板布置在加热器模块的顶部,支撑要处理的晶片,并提供污染屏障。 加热器模块耦合到电源,其适于向加热器模块提供变化量的功率,以将加热器模块保持在恒定的背景温度,即使当晶片经历来自LTP激光束的空间上和时间上变化的热负载时。 因此,来自激光器的热量通过加热器模块和绝缘体层从晶片传递到散热器。 在没有激光加热的情况下,根据需要也从加热器模块转移到晶片以保持恒定的背景温度。
