Problems and Shutdowns

Problem  27 Nov K2C Gold Target AJA new target ordered -> A new target has been ordered, will update when we have an eta. right now eta is 2-3 weeks from today. olms0025
Problem  18 Dec P4 Aligner Suss MA6 Loss of Vacuum error when loading 4 in wafers -> After loading wafer into MA6 a loss of wafer vacuum error appears. If you confirm with enter the tool will find WEC properly and will expose. This will probably be an issue for other wafer sizes as well. jorex023
Problem  18 Dec K3 Sputterer AJA1 waiting for power supply parts -> Power supply is at vendor and we are still waiting for parts before it can be repaired and shipped back. will update when we have more information. olms0025
Problem  6 Feb P4 Wet Bench Develop Light burnt out -> The light is burnt out on the left side of the bench. parme033
Problem  3 Mar P2 Etcher Ion Mill Intlvac Waiting for new Cryo -> Cryo Temps on this tool are higher then normal but vacuum still looks great. Cryo temperature interlock setpoints changed from 15K and 18K to 28K and 35K while a new cryo is being sourced. mikke168
Problem  3 Mar P5 AFM DI5000 Needs new tip before use -> I used my own tip and a new tip will need to be installed before using again. Tip fixter is in the black cylinder matthew.robbins
Problem  12 Mar P4 Wet Bench Develop Wetbench -> This wetbench has a CDA leak affecting water usage, the QDR is still funtional. mmargosi
Problem  12 Mar P3 Wet Bench HF Process Wetbench -> The QDR is down due to sofware issues. The rest of bench is funtional. mmargosi
Problem  12 Mar PAN 185 Gas Sorption Analyzer Parts ordering -> Replacement valves are on order, and have not arrived yet. I will call for eta if not deliverd by friday 14th. mmargosi
Problem  6 Dec K1 Oxidation Tube 14 Gate Oxide Tylan tycom central control console reliability pm -> doing biannual pm on Tycom CCC by disassembling and checking power supply voltages and cleaning PC board edge connections with contact cleaner as a reliability pm broug001
Problem  28 Nov KA2 CVIV testing IV - Computer issues -> A replacement computer is being worked on. The CV and IV HP systems can be used in manual mode. Without computer no data files can be saved. whipp003
Problem  14 Mar K1 ALD Savannah Ultratech Current Films update -> Precursors were rearragnged Al2O3, HfO2 and SnO are now available. Do not use SiO2. jorex023
Shutdown 23 Apr P1 Ellipsometer Rudolph shutdown update -> "System was making random crackling sounds and found the laser was not on. Turned system power off using key on the side." This is still in queue, will probably not get to this for several weeks. If you need the tool urgently, contact Brian Olmsted olms0025
Shutdown 16 Aug KA1 Si Nanowire Deposition exhaust off cibuzar
Shutdown 4 Feb K1 Oxidation Tube 15 General Tylan Process person wants to do some content analysis test runs in the near future -> due to T15 having been used for special project use since 2020. broug001
Shutdown 18 Feb K3 Evaporator Temescal extreme focus to get this equipment up -> to start with verifying all facilities to all items and check each for functionality before checkiing gate valve, pumps, hearth, shutter operation; chamber looks good. broug001
Shutdown 5 Mar P3 HD PCVD Plasmatherm Pump install and system reassembly resuming -> Work on this tool is slowly resuming as the UHV gets closer to completing it's bakeout. New pump is being installed, cleaning and reassembly of chamber components resumes. mikke168
Shutdown 3 Oct K1 Oxidation Tube 14 Gate Oxide Tylan serioal io error and ot TC error and torch controller needs to heat -> no steam oxidations until torch temp exceeds 650C to satisfy H2 temp interlock broug001
Shutdown 27 Nov K1 Ellipsometer Spectroscopic Woolam working through power supply issues -> replacement power supply not compatible with tool needs. Ordering new power supply. olms0025
Shutdown 11 Mar K1 Wafer Bonder SB6 Karl Suss TOOL or pin Could not be moved down -> Needing this error resolved - checking of the parts and sensors to find the paroblem. whipp003
Shutdown 12 Mar P5 Ebeam Spinner CEE2 Parts ordering -> Parts are orderd and on 6 to 8 wk back order. mmargosi
Shutdown 12 Mar K3 Evaporator Varian High Vacuum -> Removed and rebuilt accute vacuum leak. Vacuum is still high, I will service the cryo compressor next. mmargosi
Shutdown 12 Mar P1 UHV Deposition AJA chamber baking continues after system full cleaning and upgrades -> getting closer toward guaranteed base pressure of 2x10-9T broug001
Shutdown 12 Mar K3 Sputterer AJA1 field service repair update -> BW Systems is reprogramming the PLCs and boards for the HMI. They are doing this offsite and the effort is in process. olms0025
Shutdown 12 Mar P5 Ebeam Litho EBPG5000+ Vistec Possible Alignment Issue -> A user reported an error which is usually the result of a poorly aligned beam. I wil check beam alignment early in the day tomorrow, and if I can't resolve it, I will get Raith to take a look. rober074

Comments

K2C Gold Source-2 17 Feb Temescal Source In CHA -> Temescal gold source was removed from cabinet and was weighed with buttons at 251.16g. The source is being brought to PAN for use in the the CHA in bay 3. mikke168
P3 Evaporator CHA 17 Feb Gold Source Changed -> Temescal gold source was put in the CHA instead of refilling the gold. CHA gold source and its's two buttons weighed 165.76g when it was removed. The Teme gold source and two buttons weighed 251.06g when weighed before installation in pocket 3. 251.06g is the starting weight for this new gold source. mikke168
K3 Evaporator Temescal 19 Feb continuing with remaining third of items to finish -> before an Aluminum deposition qual can be run, hopefully by Friday or earlier. broug001
P3 Sputterer AJA2 24 Feb targets swapped, LiNb3 for Al -> system now has the following targets in it. LiNb3, Au, SiO2, Cu, Ti, W:Ti 90:10. rober074
P5 Ebeam Litho EBPG5000+ Vistec 10 Mar all beam files redefined 3-9-2025 -> all beam files, from 80pA to 250 nA, redefined 3-9-2025. rober074
K1 Wafer Bonder SB6 Karl Suss 10 Mar Last Error mesg -> Error displayed was TOOL or pin Could not be moved down is being looked at. whipp003
KA1 Dicing Saw DAC 552 11 Mar everything blade installed -> the everything blade is currently installed. rober074
P4 Wet Bench Spinners 12 Mar Power -> A FM WO is submittd to evaluate the power on this bench, currently it is funtioning as expected. mmargosi
