Developer-1 and Developer-2

Developer-1 (right) and Developer-2 (left) are located in C-1

Feedback to this section: click here

Developer-1 and Developer-2 are manual developer baths for submersion development of AZ 5214E and AZ 4562 resists in AZ 351B developer. The developer is mixed 1:5 in water by the user, and the wafer cassette is agitated manually by the user during development.

The user APV, and contact information can be found in LabManager: Developer-1 Developer-2

Process information

Before using one of developer baths, please check the "Litho4_Dev-7up-KOH" logbook to find out when they were last used. A fresh bath can be reused without problems.
The main rule is a developer made yesterday must be changed.
Rinse substrates with water for 4-5 min. after development.
Spin-dry substrates or dry with nitrogen gun after rinsing.

Standard development time using vigorous agitation:

AZ 5214E:

1.5µm resist: 60 sec
2.2µm resist: 70 sec
4.2µm resist: 3 min

AZ 4562:

10µm resist: 5 min

Procedure for making a new developer

1. 800ml "Developer AZ 351B" is mixed with 4000ml water in a special container in the fume hood.

2. Fill the bath with the developer mixture and heat it to 22 °C before use.

SU8-Developer

Feedback to this section: click here

The SU8-Developer bench is a manually operated chemical bench for submersion development of SU-8 photoresist in PGMEA (supplied in the cleanroom as mr-Dev 600). After development, the substrates are rinsed with IPA and dried in the bench.

The user manual, user APV, and contact information can be found in LabManager

Developer-TMAH

Feedback to this section: click here

Developer-TMAH is a manually operated, single substrate spray-puddle developer. It uses the TMAH based AZ 726 MIF developer (2.38 % TMAH in water with a small amount of wetting agent).

The user manual, user APV, and contact information can be found in LabManager

Process information

Standard recipes
