Narrative:
Aircraft X was cleared for the RNAV approach and descending on the approach. I took the radar handoff on aircraft Y from tower while aircraft Y was still not a conflict. Aircraft X was at 3;000 feet and the two aircraft were now on a converging course and appeared likely to merge. Aircraft X had a crossing altitude of 1;500 feet on the next fix on the approach. Aircraft Y was climbing out northeast bound. At approximately 1;500 feet I called tower and told them to turn aircraft Y or to transfer communications to me. I told aircraft X to continue present heading and to maintain 3;000 feet.at this point aircraft Y was at 1;700 feet and I was anticipating them to continue climbing. I did not receive communications with aircraft Y until after the targets merged and aircraft Y was across the aircraft X's final approach course. Where the targets merged aircraft X should have been below 2;400 feet descending to 1;500 feet for their next crossing restriction. After the targets merged I cleared aircraft X for the visual approach. At this point they were on approximately a seven mile final at 3;000 feet; almost to the fix that they should have been at 1;500 feet. This set them up for a less than stable approach to the runway.I recommend that tower and TRACON meet to collaborate on a safer and more efficient way to handle VFR departures that are going to cross the oak finals.
