摘要:
A method and apparatus for measuring node voltage on an integrated circuit is disclosed herein. A sensing needle 10, wich is connected to supply voltage 20, is positioned directly above node 12 on integrated circuit 14. Tunneling or field emission current 30 is produced in sensing needle 10 due to the difference in potential between sensing needle 10 and node 12. Supply voltage 20 is adjusted to set current 30 to an initial value. When the voltage on node 12 changes, the current 30 will also try to change. When a change in current 30 is detected, a signal 28 is generated to adjust supply voltage 20 such that current 30 returns to its initial value. Consequently, the change in supply voltage 20 mirrors the change in voltage on node 12.
摘要:
The deposition of zinc sulfide films (16) using dimethylzinc (46) and hydrogen sulfide (44) in a vacuum processor reactor (50) provides a low temperature process applicable for high volume production of infrared focal planes. These layers (16) of zinc sulfide are used as insulators and infrared anti-reflective coatings which are free of contamination relative to physical vapor deposited ZnS films. The zinc sulfide layers (16) are formed by evacuating a chamber (62) and mixing hydrogen sulfide gas (44) and dimethylzinc gas (46) at. specific operating conditions until the desired ZnS film thickness is obtained. The rate of growth of the zinc sulfide (16) film is controlled by varying the temperature, pressure, and the relative flow rates of the hydrogen sulfide gas (44) and the dimethylzinc gas (46).

摘要:
A multi-electrode plasma processing system (10) provides flexible plasma processing capabilities for semiconductor device fabrication. The plasma processing equipment (10) includes a gas showerhead assembly (52) a radio-frequency chuck (24), and screen electrode (66). The screen electrode (66) includes base (68) for positioning within process chamber (10) and is made of an insulating material such as a ceramic or teflon. A perforated screen (70) is integral to base (68) and generates a plasma from a plasma-producing gas via a radio-frequency power source (104). The screen (70) has numerous passageways (78) to allow interaction of plasma and the process chamber walls. The screen (70) surrounds showerhead assembly (52) and semiconductor wafer (22) and can influence the entire semiconductor wafer plasma processing environment (62) including the plasma density and uniformity. The circuitry (74) electrically connect screen (70) to a power source (100) or (104) to cause screen (70) electrode to affect process plasma density and distribution. Any of the plasma electrodes showerhead assembly (52), chuck (24), or screen electrode (66) may be connected to a low-frequency power source (108), a high-frequency power source (100 or 132), electrical ground (110), or may remain electrically floating (94).
