    • A system for measuring the temperature of a semiconductor wafer 12 comprises a light source 14, a photodetector 20 which is operable to determine light intensity, and a mirror 18 in a predetermined fixed position from a beam splitter 16. The components are positioned such that light from the light source 14 impinges the beam splitter 16 and subsequently reflects off the mirror 18 and the wafer 12 and is received by the photodetector 20. Changes in the temperature of the wafer 12 are calculated based upon changes in the intensity of the received light which depends upon the expansion/contraction of the wafer. The absolute temperature may be calculated based on a known reference temperature and the changes in wafer 12 temperature. A second system and method for measuring the temperature of a semiconductor wafer which includes the use of a plurality of mirrors and two beam splitters is also disclosed.

    • A process module which is compatible with a system using primarily vacuum wafer transport, but which permits processing multiple slices in parallel in a single module. This is accomplished by using notched quartz arms in the module, so that the transfer arm can place each of several wafers into one set of notches in the quartz arms. Optionally, a vertical degree of movement in the arm may be used to accomplish this, and the quartz arms may be immovable. This means that the port from the multi-wafer module into the wafer transfer system must be high enough to accommodate the necessary vertical movement of the transfer arm. After the transfer arm has placed the wafer on the quartz arms, the process module can be elevated to close around the set of wafers and made a seal. If the wafer transport arm is already configured to access wafers directly out of a multi-wafer vacuum wafer carrier, the necessary degree of freedom will necessarily already be present in the transfer arm, and at least one port of the necessary vertical dimensions will necessarily also be already present (between the loadlock and the transfer chamber). This is particularly useful in combination with relatively slow processes, such as thick field oxidation, long anneals, or long furnace heating steps used to drive in diffusions.
    • 一种与使用主要是真空晶片传输的系统兼容的处理模块,但是允许在单个模块中并行处理多个片段。 这通过在模块中使用缺口石英臂来实现,使得传输臂可以将几个晶片中的每一个放置在石英臂中的一组凹口中。 可选地,可以使用臂中的垂直移动度来实现这一点,并且石英臂可以是不可移动的。 这意味着从多晶片模块到晶片传送系统的端口必须足够高以适应传送臂的必要的垂直移动。 在传送臂已经将晶片放置在石英臂上之后,可以将处理模块升高以围绕该组晶片闭合并且形成密封。 如果晶片传送臂已经被配置成直接从多晶片真空晶片载体中进入晶片,则必需的自由度必然已经存在于传送臂中,并且必要的垂直尺寸的至少一个端口也将必然地 已经存在(在负载锁和转移室之间)。 这特别适用于相对较慢的工艺,例如厚场氧化,长退火或用于扩散驱动的长炉加热步骤。
