    A method has been developed for achieving uniform levels of refill over a wafer during the selective epitaxial refill process. This is accomplished by eliminating local turbulent gas flow across the surface of the wafer which had contributed to the non-uniformity of the wafer. When wafers 1 (Fig. 1) were examined, it...

    It is important that the Personal Computer (PC) system response be as close to the entry speed of the operator as possible so that productivity can be increased and frustration decreased. The speed of the application is directly related to the size of the files. Each time an invoice is created, a verification has to...

    A method is described which frees the user from remembering which application works on which kind of data. In a system that has multiple applications and multiple data types and formats, it is difficult for a user to know which applications work on which types of data. For example, if a user wants to edit a document,...

    A robot controls a multiposition Z-axis actuator through its digital in (DI) and digital out (DO) switches. A robot 1, such as an IBM 7535 or 7540 robot, for example, has a casting 2 attached thereto by screws 3. The casting 2 supports an electric motor 4 having its output shaft connected through a trans mission 5,...
