A test pattern to monitor the outgassing of boron and phosphorous in boron phosphorous silicon glass (BPSG) films was developed. The outgassing effect on the etching rates was studied by varying the reflow temperature in a nitrogen atmosphere. The wet etching rate reduced effectively and improved the contact profile due to loss of the phosphorous near the BPSG surface. The contact process was used for the mass production of dynamic random access storage (DRAM) devices.
