Abstract: PROBLEM TO BE SOLVED: To provide a method for reducing and eliminating the strain of a plastic package. SOLUTION: A semiconductor module includes a semiconductor chip, a lead frame having a lead finger, and a down set member being in a mounting medium for reducing the strain and giving a flat package by balancing thermal stress between the lead finger and the mounting medium. The down set member may be the bent part of the lead frame. The down set member may be another body such as a dummy semiconductor chip.

Abstract: A semiconductor module includes a semiconductor chip, a lead frame having lead fingers, and a down set member within an encapsulant for reduce warpage and providing a more planar package by balancing thermal stress between the lead fingers and the encapsulant. The down set member can be a bent portion of the lead frame. It can also be a separate body, such as a dummy semiconductor chip.

Abstract: A SEMICONDUCTOR MODULE INCLUDES A SEMICONDUCTOR CHIP, A LEAD FRAME HAVING LEAD FINGERS, AND A DOWN SET MEMBER WITHIN AN ENCAPSULANT FOR REDUCE WARPAGE AND PROVIDING A MORE PLANAR PACKAGE BY BALANCING THERMAL STRESS BETWEEN THE LEAD FINGERS AND THE ENCAPSULANT. THE DOWN SET MEMBER CAN BE A BENT PORTION OF THE LEAD FRAME. IT CAN ALSO BE A SEPARATE BODY, SUCH AS A DUMMY SEMICONDUCTOR CHIP.

Abstract: A system is disclosed for presenting information which reflects the users' c ultural preference, including language and other conventions, that can manage locale categories without requiring application programs to manage all the overhead of repetitive changes to locale category values. Users merely specify their cul tural preferences through the application programs and the operating system assign s a stack from the working memory for each specified category of cultural prefer ence, and pushes onto the stack the location in the working memory of a file for the c ategory of cultural preference specified, the file having been transferred from a local e database of files that contain code formatting according to the cultural preferences. In a second aspect of the operating system, multiple concurrent sets of cultural preferences are handled by determining whether a location in the working mem ory corresponding to the preference specified is currently in the queue, and if not, by placing a new value in the queue for each memory location corresponding to a n additional set of locale category values.
