Abstract:
A memory device comprises a semiconductor substrate with memory (16) and logic device areas (18). A plurality of memory cells are formed in the memory area, each including first source and drain regions with a first channel region therebetween, a floating gate disposed over a first portion of the first channel region, a control gate disposed over the floating gate, a select gate disposed over a second portion of the first channel region, and an erase gate disposed over the source region. A plurality of logic devices are formed in the logic device area, each including second source and drain regions with a second channel region therebetween, and a logic gate disposed over the second channel region. The substrate upper surface is recessed lower in the memory area than in the logic device area, so that the taller memory cells have an upper height similar to that of the logic devices.

Abstract:
An inspection system and method for inspecting a sample surface, with a light source for generating a probe beam of light, a high NA lens for focusing the probe beam onto a sample surface, and collecting a scattered probe beam from the sample surface, optics for imaging the scattered probe beam onto a detector having a plurality of detector elements that generate output signals in response to the scattered probe beam, and a processor for analyzing the output signals to identify defects on the sample surface. Shaping the beam into a stripe shape increases intensity without sacrificing throughput. Offsetting the beam from the center of the high NA lens provides higher angle illumination. Crossed polarizers also improve signal quality. A homodyne or heterodyne reference beam (possibly using a frequency altering optical element) can be used to create an interferometric signal at the detector for improved signal to noise ratios.
