The present application incorporates by reference each of the following applications which are related cases of a common assignee and contain related subject matter: One of the basic problems in integrated circuit manufacturing is defects caused by the presence of particulates.
For example, if photolithography with 0. This problem is becoming more and more troublesome because of two trends in integrated circuit processing: First, as device dimensions become smaller and smaller, the size of a "killing defect" becomes smaller, so that it is necessary to avoid the presence of smaller and smaller particles.
This makes the job of making sure that a clean room is really clean increasingly difficult. For example, a clean room which is Class 1 i. Second, there is an increased desire to use large size integrated circuits. For example, integrated circuit sizes larger than This means that each fatal defect is likely to destroy a larger area of processed wafer than was previously true.
Another way to think of this is that not only has the critical defect size decreased, but the critical defect density has also decreased. Thus, particulates are not only an extremely important source of loss in integrated circuit manufacturing yields, but their importance will increase very rapidly in the coming years.
Thus, it is an object of the present invention to provide generally applicable methods for fabricating integrated circuits which reduce the sensitivity of the process to particulate contamination.
One of the major sources of particulate contamination is human-generated, including both the particles which are released by human bodies and the particles which are stirred up by equipment operators moving around inside a semiconductor processing facility front end.
To reduce the potential for particulate contamination from this major source, the general trend in the industry has been to make more use of automatic transfer operations. Using such operations, for example, a cassette of wafers can be placed into a machine, and then the machine automatically transfers the wafers, one by one, from the cassette through the machine to effect the processing steps necessary and back to the cassette, without manual assistance.
However, efforts in the area of automatic transfer operations have served to highlight the importance of a second source of particles, namely particles generated by the wafers and the transfer mechanisms during handling and transport operations.
When the surface of the wafer jostles slightly against any other hard surface, some particulate of silicon, silicon dioxide, or other materials is likely to be released.
The particulate density inside a conventional wafer carrier is typically quite high, due to this source of particulate. Moreover, many of the prior art mechanisms for wafer transport generate substantial quantities of particulate. The general problem is discussed in U. Some types of wafer processing are shown in U.
The prior applications of common assignee discussed above addressed this facet of the problem by providing a vacuum wafer carrier in which particulate generation due to abrasion of the surface of the wafer during transport is reduced.A small wearable recall device is provided to capture images triggered by a combination of a detection of a capture condition (e.g., changes in motion, temperature or light level) followed by a relatively stable period, as detected by an accelerometer.
By triggering on the combination of a detected capture condition followed by a detected stability condition, a clearer image of the environment.
