Optical-laser production lifts demand for JEOL’s beam writers
JEOL makes electron microscopes, analytical instruments and electron-beam lithography systems. It supplies research, development and semiconductor-manufacturing operations with equipment for examining material structures and writing very fine patterns.
Spot-beam orders and sales both increased

Writing the grating inside an optical laser
Where a laser manufacturer uses the beam writer
A simplified part of DFB-laser production. Equipment, materials and grating pitch are not drawn to scale.
Optical-device manufacturer
Prepare a resist-coated wafer
The material is a compound-semiconductor wafer coated with resist for patterning.
Wafer into the writerJEOL’s beam writer
Write the grating pattern
A spot electron beam writes the pattern that will become the diffraction grating.
Patterned wafer to later processesCustomer’s later processes
Form the grating, then the laser chip
Development, etching, regrowth, electrode formation and chip separation produce the light-emitting component.
JEOL supplies the writing equipment. The laser is completed through several customer manufacturing processes.

Different writers faced different demand

THE VIEW AFTER THE NUMBERS
What the numbers suggest
JEOL’s equipment is used both to examine material structures and to pattern the fine features of optical lasers. Following the specific task on the production line explains why a customer needs each machine.
A laser-grating writer and a photomask writer serve different customer production processes. In the year ended March 2026, those roles brought different demand: spot-beam orders and sales rose while mask-writer unit sales fell.
