I'm not going to write your function for you but the following should
help you get started.
dict.keys() <-- returns a list of the keys in your dictionary
[130nm,180nm,250nm]

Here you want to check if the key in the child dictionary matches some
text:
Eg:
Foundry = 'umc'
FoundryList = []
for key in dict.keys:
val = dict.get(key)
if Foundry in val.keys():
FoundryList.append(key)
print FoundryList
[130nm,250nm]

Same concept here:
Process = ['2p6m_1.8-3.3_sal_ms']
ProcessList = []
for key in dict.keys():
val = dict.get(key)
if Process in val.values():
ProcessList.append(key)
print ProcessList
[180nm,250nm]
So key concepts you need are:
- Get a list of keys from the dictionary <-- dict.keys()
- Get the value matching a key <-- dict.get(key)
- Get a list of values from the dictionary <-- dict.values()
This should be enough to get you going.
