    摘要: A high-performance "low-RC" multi-level interconnect technology has been conceived for advanced sub-0.5 .mu.m semiconductor technologies. The proposed structure and fabrication process has a number of significant characteristics: (i) compatible with various metal systems (Al, Cu, W, etc.), (ii) free-space interlevel dielectrics; (iii) compatible with standard semiconductor fabrication processes, (iv) excellent mechanical stability; and (v) compatible with hermetically sealed chip packaging techniques. Compared with an Al-based conventional interconnect technology, the new interconnect system can reduce the "RC" delay by a factor of .sup.- 6. The proposed interconnect technology offers major chip performance improvements such as lower power dissipation and higher operating frequencies. This technology is based on a manufacturable process to fabricate multilevel interconnect with free-space dielectrics and a technology scaling enabler.

    摘要: A multi-zone illuminator for processing semiconductor wafers is described which comprises a plurality of source lamps and dummy lamps embedded in the reflector side of a lamp housing. The source lamps are arranged in a plurality of concentric circular zones. The illuminator also comprises plurality of light pipes for receiving multi-point temperature sensors to measure the semiconductor wafer temperature and its distribution uniformity. A gold-plated reflector plate is attached to the bottom side of the lamp housing for reflecting and directing optical energy toward the wafer surface. The distance between the reflector plate and the wafer and the lamps and the wafer may be adjusted with the use of a spacial elevator and adaptor assembly. The multi-zone illuminator allows uniform wafer heating during both transient and steady-state wafer heating cycles.

During actual RTP reactor operation, the data from the calibration tables and current wafer and window pyrometer measurements are used to compute corrected wafer temperature(s). The corrected wafer temperature(s) is/are then used to control the intensities of the heating lamps according to the wafer processing heating schedule.
