The system can be characterized as follows:
The system can be characterized as follows:


*The spot beam for electron beam writing is generated by a ZrO/W emitter and a four-stage electron beam focusing lens system, see illustration below.
*The spot beam for electron beam writing is generated by a ZrO/W emitter and a four-stage electron beam focusing lens system.
*Electron-beam scanning speeds, f, up to 100 MHz are available (which is maximum scan speed).
*The maximum frequency of the deflector scanner is 100 MHz, i.e. the minimum beam dwell time is 10 ns.
*The acceleration voltage is 100 kV.
*The acceleration voltage is locked at 100 kV.
*The e-beam writer can pattern structures with a minimum resolution of 12 nm.
*The e-beam writer can pattern structures with a minimum resolution of 10 nm.
*The maximum field-size without stitching is 1000µm x 1000µm.
*The maximum writing field size is 1000 µm x 1000 µm.
*The machine has cassettes that can contain either 6 wafers of 2” in size, 2 or 3 wafers of 4” in size, 1 wafer of 6” in size, 1 wafer of 8” in size, 4 chips of different sizes(slot sizes 4 mm, 8 mm, 12 mm, and 20 mm)
