In older manufacturing nodes (e.g., 90nm or larger), a small amount of particulate contamination might not have rendered a die unusable. However, in today's leading-edge nodes (7nm, 5nm, and 3nm), a single particle of dust or a microscopic flake of material from a worn guide rail can destroy the functionality of an entire chip.

A: Possibly, but only if it starts with $$ BEGIN_MAP . Open it in a text editor. If you see simple row/column data without $$ commands, it is a proprietary format, not SEMI E49.6 compliant.

A: Partially. The map content follows E49.6, but the transport can be via SECS-II streams (S6,F11). Check the PDF's annex on "Embedding E49.6 into GEM."
