67th day at SSMC.
Today, I had experienced troubleshooting can be time consuming. We experienced an error in the Excel's formula and I had spent time troubleshooting it. It was finally resolved with my supervisor's help. It turned out to be errors from long before.
After which, I had 'undo' the classifications done in the wafers yesterday by changing all classifications to 'reject'. This was done because the result achieved yesterday was not acceptable. Thus, my supervisor had asked me to change all classifications back to the original state that is the reject status.
Continuing the classification task, I had exported the pre classification data out for another round of GR&R calculations. It sounded easy when describing however, it was really a time consuming and tedious task. >.< LOL...
In the later afternoon, supervisor had asked me to translate some documents from Chinese to English. Wonder if I had done it correctly, I am quite worried that I had misinterpreted some meanings... >.<
That's all for today.

Week 15 - 22 Jan 2013 - Tue
66th day at SSMC.
Today was cold... Raining since morning, or was it from last night? Anyway, cold weather...
This morning I had continued to search and look for formula to display the respective DCOP when the location is matched. I was stuck at this step since yesterday. I guess the Excel help function isn't so useful after all. I had tried several formula like 'IF', 'MATCH', 'LOOKUP' and more and even combining them, hoping to get what I want, however, the result wasn't successful.
Solution always comes after rounds and rounds of circle. I gad no idea how but I had finally managed to resolve this problem with the 'LOOKUP' function. After several tries, I had rearrange the locations in alphabetical order and the result turned out working perfectly. I was totally speechless when I achieved it. -.-
When you have nothing to do, something is better than nothing. Some errand tasks had helped me to pass time today. LOL... Well, at least I've gotten to explore more places in this company before attachment ends. Haha...
After lunch, my supervisor had asked me to do the classification of wafers for the runs done yesterday. Similar to the last time, I had only accepted or rejected based on the pictures of the wafers. After which, I had exported the data out to do the GR&R calculations. This task was really time consuming and tedious. LOL...
That's about all for today.

Week 15 - 21 Jan 2013 - Mon
65th day at SSMC.
Today is the first day if week 15 which is also the second last week of my attachment. Time flies, 14 weeks had past and my attachment is coming to the last 9 days.
Last week, I had officially finished my project for this attachment and all school assignments are currently in process.
As the implementation period for my project is not within my attachment period, thus there is no official result achieved. However, my supervisor had allowed me to test the pilot run result to compare the before and after benefits that my project had brought about to the system.
And according to the pilot run result that I had obtained, the implementation if my project will be able to shorten the usual routine steps from 7 steps to 4 steps and the time spent on these steps will be reduced by 85%.
I really hoped that the pilot run result can bring about convenience to the company's system and increase their productivity.
Alright, back to today's tasks. As a start in this morning, I had helped to update some charts to their most recent values for report analysis purposes.
Next, supervisor had asked me to check the measuring point locations in the ball room area against the map drawn out by the OQA staff to see if the availability of the points matched. After which, I had created a list of DCOPs against the point locations and used formula to check if they are matched 1 to 1. This is done for the continuation of my project in the company, however, not for school purpose.
After creating the list of DCOPs and locations, we will need to consult the IT personnel on the idea of this further step. And good news was heard from the IT personnel! Thus, I had continued to do preparation steps.

Week 14 - 18 Jan 2013 - Fri
64th day at SSMC.
Today is the last day of week 14 and this means that attachment has left the last 2 weeks. But why am I not excited about it? Must be all the school assignments are keeping my happiness away from me... >.< LOL...
Anyway, this morning, as usual, I had updated the daily defect task and had helped my supervisor to create a PowerPoint slides regarding the fab shut down recovery status with information given by supervisor.
After which, my next task was to update an analysis Excel file with the information done from yesterday's root cause status Excel file task. After ensuring that the data inputted are correct, I had updated the analysis charts to the most recent values and I had used formula to calculate the values of the charts.
That's all for today.

Week 14 - 17 Jan 2013 - Thu
63rd day at SSMC.
Today, after meeting our LO in the morning, I had reported the drop test results on Monday to my supervisor as well as showed her the photographs that I have taken. Afterwards, I had updated the daily defect task as my first assigned task for today.
After which, supervisor had assigned me another task which is to update an Excel file regarding the root cause status of the report cases and the corresponding actions taken. For this task, I had checked the required information from the PowerPoint slides provided by supervisor and then indicated the information into the Excel file.
In the afternoon, I had another errand task as supervisor was busy in the fab, I had helped to collect back the wafers, used fir the drop test on Monday, from the vendor on her behalf. (^^)
After collecting the wafers back to the office, supervisor had asked me to open up the box and check if the wafers are intact that is whether there is any broken wafer. Since there is no broken wafers, the last test turned out to be successful too! (^^)
That's all for today! Tomorrow will be Friday! Hope that this will make my day. ;)

Week 14 - 14 Jan 2013 - Mon
62nd day at SSMC.
Today, as my supervisor was on leave, I was tasked to update the charts in the weekly report to the most recent data on behalf of my supervisor.
After which, there was some errors in the Excel file that I had improved on. The data was inserted under the wrong defect type. Thus I had spent some time troubleshooting for the cause of the errors and the solution. It was resolved in the end. (^^)
Last week, I was told by my supervisor to go for a drop test on her behalf today. And in the afternoon, I had met up with the vendor at the warehouse to collect the 4 boxes of wafers for the test before proceeding to the place for the test. I had taken photos during the test as evidence for my supervisor.
For this week, tomorrow and Wednesday are company off days and we are not required to work!!! Time for resting (^^) and school assignments >.<
Time flies? This attachment left the last 3 weeks including this week...

Week 13 - 11 Jan 2013 - Fri
61st day at SSMC.
Today is Friday! This morning I had checked the environment monitoring data for the month December, on behalf of my supervisor. After enduring the data tally, I had returned to supervisor for signing.
After which, supervisor had downloaded an Excel file with the formula calculating GR&R. And I had used it to calculate the result of supervisor's data. GR&R stands for Gage Repeatability and Reproducibility and it is used to assure measurement system is used adequate for the purpose it is being used. I know it's complicated. Anyway, I had pasted the data values into the Excel file and the result had appeared. (^^)
After lunch, supervisor had taught me how to do classification for the wafers that is to check each wafer picture and determine whether that part is accepted or rejected. For pictures that show stain or scratch-like thing, I will reject those parts. I had done classification for 3 runs of wafers and exported the data out of the system.
After which, I had to insert the classification data into Excel file to summarise the data into table. After summarising the data, I had inserted that summarised result into the GR&R Excel file to get the result.
That's all for today. Time to enjoy weekends!!
