Process optimization using the Picoscope

The original standard recipes on Pegasus 1 differ in many ways. The second step of one of them is listed below:

Process A parameters
Step 2
Parameter	Etch	Dep
Gas flow (sccm)	SF₆ 350 (1.5 s) 550	C₄F₈ 200
Cycle time (secs)	7.0	4.0
Pressure (mtorr)	25 (1.5 s) 150	25
Coil power (W)	2800	2000
Platen power (W)	140 (1.5) 45	0
Cycles	44 (vary this)
Common	Temperature 20 degs, HBC 10 torr, Short funnel, with baffle & 5mm spacers
