No tools went down today, we had a ton of work for 72. It was full all day. There was also a lot of work for the descum tools. I would go and collect 15 lots (which would all be done in about 5 hours if the next lot is loaded as soon as the last is done). When there were 3 lots left, I checked to see if any more were out waiting and there were over 20! So I collected more to fill the rack. D1 said it was that busy for them as well. 11 Ash is getting close to a maintenance qual. It's about 800 away. I predict it will go down on Wednesday at about 1000 away. Today was not as eventful as yesterday.

Passdown told us descum and 72 were the same amount busy, fully loaded all day with a lot of product still waiting to be ran. Been talking to MMJ on ways to hang out outside of work and we have a mutual love for "I Love Lucy". I have the box set and so now we just need to find nights where our schedules are free to binge watch.
Tuesday, I was in my Bay alone and started hearing a beeping sound. I checked all my tools and none had alarms going off on them. So I left the Bay thinking it was the sink on 5A. As soon as I left the bay, I didn't hear it anymore. I thought it was done. I went back into my bay and there it was again. I paged MMT and asked if they could check the subfab under my bay for an alarm. An hour later, the alarm stops. MMT finds me and asks if it was stopped. "Yep . Thanks!".
Sandy walked in to use the computer and I asked if she could hear the beep. She looked at me and said what beep? She waited a few seconds and then said, "Nah, I hear it." I think she wanted me to think I was crazy.
I was told today that the paperwork has been submitted for me to train the new person starting Sunday. Yay!
72 finally went down today, it was running with no errors for 2 days straight. Chamber 2 went down for an endpoint error. It use to do this a lot. It hasn't had an endpoint error for a while. It took the engineer another couple of hours to come look at it. The second time it went down, it went straight to maintenance, which is also for the engineer. The issue with the second time was because I ran a sign/wafer and the machine did not have a second wafer to compare it to. So it thought there was a issue and shut itself down. The engineer said he is going to have to change the chart in the tool so it doesn't do that again if there is only one wafer in the lot.
24 went down as well but I didn't know it was running or that it was down until MMT came up and said he signed back over to me and continued to process the lot. There ended up being more work for 24 as the night went on.
Near the end of shift our engineer needed to borrow 24 to run some test wafers because they are wanting to add some more recipes to it, and covert it for the new company. Now like Descum, 24 etch is qualed on a counter, unlike Descum, it isn't by wafer count, it is by hours the tool has ran with wafers, 24 etch's qual count is 2 etching hours. If there is a lot of work and it runs back to back that can be as little as 2 days, but if there is no work for weeks or months, then it doesn't need to be done. One thing our engineer did was use up the last remaining hour before Qual. So when he was done, it went down. I was on break and David wasn't paying attention to it so we didn't notice until 5:30 am. We apologized for passing down Qual, but oh well.
The next thing our engineer did after he was done using 24 etch was tell us that for the descum, Qual, we no longer needed to use the tencor to pre/post read PCs just the SP1s. We have the at passdown.

Today started our with a lot of broken down machines. 52 ash was down, I don't know what the initial problem was but the Maintenance man on D1 decided to put it down to P.Maint and left it down all shift. As I predicted, because I'm awesome, 11 Ash went down for preventive maintenance.
Funny story the MM signed it back up because they didn't have the needed parts in stock that needed to be changed out. Said, "on order" unknown time of arrival. I'm thinking they ordered this morning...
As day shift did the Qual for 24 etch, they realized a new task was added to 24 that needed to be done twice daily. Twice daily?! 24 is hardly used, and a lot of full product takes nearly 2.5 hours.
Tuesday, after the engineer told me that tencor is not needed for Quals, I let him know I had concerns about the SP1. I had a task Qual due for 53 ash Wednesday and said I could show him my concern. He agreed.
On top of my task for 53, 52 was already down and 54 was less than 50 away from going down to it's preventive maintenance. Down 3 ashers is NEVER fun and a new task yay! Okay I do 2.5/3 of the task for 53, page the engineer to come by so I can show him my issue with SP1. I then start the task for 24 while waiting, over an hour and a half goes by and the engineer has not stopped by. By this time I've completed the task in 24 and 54 went down. I really needed to bring up my working asher so I decided not to wait any longer. I was walking down the main hall, I saw the engineer talking to someone about a game. I stood next to him until they stopped talking and looked at me. I asked if he got my page and I was going to post read now, he looked at his pager and said "Oh, there it is..."
Either way, we got to the SP1, I started post reading and said "I'll be very mad if this doesn't mess up like it usually does..." Fortunately, it did. He noticed my concern and said he would figure out why that is happening. Either way it's still going to be the only pre/post reader we use.
He took this moment to tell me that he added the new task to 24. I told him I knew and already completed it. He looked shocked and amazed. 54 was down for another 3 hours before maintenance added a comment asking for an extension on the P.Maint because they didn't have the manpower to have two department MM working on P.Maint tools. Since 52 was already down. 54 came back up, 52 was down the rest of the night.
On Sunday, I have the exciting opportunity of training a new temp. I also hope I get the paperwork to get hired with benefits...I for reals need to go to doctor. My neck and shoulder still hurt. But I have no insurance, so nope.
