Significant design improvements have been made to Oxford Instruments’ wide temperature range electrodes.
Features of the electrode re-design upgrade
Increased structural strength of the electrode across the entire temperature range (-150ºC to +400ºC) Delivers improved dimensional stability of the electrode, maintaining flatness of the upper surface and hence efective heat transfer to and from the wafer
Up-rated heating element to 2kW Delivers more heat to the electrode thereby reducing temperature ramping times, increased element lifetime and improved temperature uniformity over the upper surface
Design allows fitting of two temperature probes Temperature control and over temperature limit “watch dog” provision
Increased fluid flow capacity within the electrode Delivers increased cooling performance at the wafer, allowing a wider range of processing parameters to be employed
Re-design of temperature probe with increased dc bias capability Increased processing window with dc bias capability to 1kV, up from 500V limit of previous design
