I haven't come across a hidden name like this before. Chip art or names on a die are usually much easier to see. Rafi Retter's initials are also in the middle of the 8088 die, much more visible since it's in the metal layer and separated from the circuitry.
The 8088 processor was designed by Intel Israel (i/IL on the die). Intel Israel also designed the Intel 8087 floating point coprocessor chip. Intel's Israel site was opened in 1974, Intel's first design and development center outside the US.
