Developer-1 and Developer-2 | |||
There are 2 developer baths, develop 1 and develop 2, witch are the same. | |||
and | |||
'''The | Here are some main rules for developer baths use: | ||
*Before using a one of developer batch's please check the "Lithography logbog1" to find out when they were used last time. The fresh bath can be easily reused. | |||
*The main rule is the develop from yesterday must be changed. | |||
*Substrates rinses with with water for 4-5 min. after developing. | |||
*Substrates can been spin-dried or dried with nitrogen gun after the rinse. | |||
The standard developing time AZ resist: | |||
*1.5µm resist is 60 sec | |||
*2.2µm resist is 70 sec | |||
*4.2µm resist is 3 min | |||
*9,5µm resist is 5min. | |||
====The procedure for making a fresh developer==== | |||
1. 800ml "Developer AZ 351" is mixed with 4000ml water in a special container in the fume hood. | |||
2. Fill the bath with a fresh developer and heat it to 22<sup>o</sup>C before use. | |||
