How we counted: 1066 open Process Engineering (Semiconductor Process) roles from 55 employers tracked in the SemiconductorJobs index, counted 14 Nov 2026. Specialty figures count only roles carrying this exact specialty label, so an employer's related work in neighbouring specialties is not included there, and is counted in the wider Process, Fab & Equipment family row. Days are counted from when our index first saw each posting, not from the employer's original posting date.
