Project Number 1

Summary:

Ran search using vendor supplied information and data from All Tests database.

Test Objective:

Develop contamination removal process that uses minimal water.

Product Use:

Microelectronic substrates: metallized using either thin or flick technologies.

Trial Number	Date Run	Purpose	Success Rating
0	06/16/1999	Information request for cleaning alcohol	Technology Transfer.
1	06/30/1999	To evaluate several aqueous cleaners for the removal of the PVA.	Preliminary compatibility tests on substrate coupons encouraging for at least one cleaning chemistry. More in-depth laboratory testing necessary.
2	07/11/1999	To evaluate the one cleaner not available for the first trials.	A follow up test, usually based on company input.
3	08/02/1999	To evaluate the effectiveness of four selected cleaners based on previous testing results.	A follow up test, usually based on company input.
4	08/08/1999	To further evaluate the effectiveness of the two best cleaners based on previous testing results.	A follow up test, usually based on company input.
5	08/15/1999	To determine a method for evaluating soil loading of cleaning solutions.	A cleanliness study, addressing only various analytical techniques.
6	08/15/1999	To further evaluate the effectiveness of the two best cleaners using a thicker Evanol solution.	A follow up test, usually based on company input.
7	08/30/1999	To evaluate cleaning at different levels of contamination.	A follow up test, usually based on company input.
8	09/02/1999	To determine if waste water stream could be reused for cleaning.	A follow up test, usually based on company input.
9	09/07/1999	To evaluate cleaning at 85 F, eeping all other parameters the same.	Test showed little or no promise.
10	09/13/1999	To determine if the addition of bleach would effect the chlorine readings.	A cleanliness study, addressing only various analytical techniques.
11	09/13/1999	To evaluate cleaning at 100 F using ultrasonic cleaning.	A follow up test, usually based on company input.
12	09/21/1999	To evaluate cleaning at 85 F using ultrasonic cleaning.	A follow up test, usually based on company input.
13	09/28/1999	To evaluate client’s current cleaning system through gravimetric analysis.	A cleanliness study, addressing only various analytical techniques.
14	09/28/1999	To measure contamination levels of cleaning solution over five days of use.	A cleanliness study, addressing only various analytical techniques.
15	10/07/1999	To evaluate cleaning at 85 and 100 F using ultrasonic cleaning.	A follow up test, usually based on company input.
16	10/07/1999	To measure contamination levels of cleaning solution over five days of use.	A cleanliness study, addressing only various analytical techniques.
17	11/01/1999	To evaluate previously cleaned coupons to determine trace amounts of contaminants	A cleanliness study, addressing only various analytical techniques.
18	11/04/1999	To measure contamination levels of cleaning solution over five days of use.	A cleanliness study, addressing only various analytical techniques.
19	11/04/1999	To evaluate previously cleaned coupons with partial contamination remaining to determine trace amounts of contaminants.	A cleanliness study, addressing only various analytical techniques.
20	11/22/1999	To measure contamination levels of cleaning solution over five days of use.	A cleanliness study, addressing only various analytical techniques.
21	12/12/1999	To qualify the proposed cleaning method to current process and laboratory system.	A follow up test, usually based on company input.
22	02/16/2000	To qualify the proposed cleaning method to current process and laboratory system.	A follow up test, usually based on company input.
