Title: Innovations of Christopher Malcolm Stanley Sears

Introduction

Christopher Malcolm Stanley Sears is an accomplished inventor based in Fremont, CA. He holds three patents that showcase his expertise in the field of electron microscopy and electron beam technology. His innovative contributions have significantly advanced the capabilities of imaging and electron source design.

Latest Patents

One of his latest patents is the Tilt-imaging scanning electron microscope. This apparatus includes an electron gun, first and second deflectors, an objective electron lens, and a secondary electron detector. The first deflector deflects the electron beam away from the optical axis, while the second deflector redirects it back towards the optical axis. The objective lens focuses the electron beam onto a target substrate surface at a tilt angle. Another embodiment of this patent relates to a method of imaging a surface using an electron beam with a tilted trajectory.

Another significant patent is the Non-planar extractor structure for an electron source. This invention features an electron emitter with a tip from which an electron beam is extracted. The electron source includes a non-planar extractor with an extractor opening larger than a built-in beam-limiting aperture. The central axes of both the extractor opening and the beam-limiting aperture are aligned with the tip along a beam axis. This patent also describes methods for generating an electron beam and an array of electron sources for producing multiple electron beams.
