Repercussions on the reliability capability and electrical performance of power p-channel LDMOS devices by different discrete-distributed architectures in the drainside are investigated in this paper. Here, in order to effectively improve the reliability issues, a drain-side "NPN" and "PNP" styles of pLDMOS-SCR with some discrete-distributed areas arrangement are fabricated by a 0.25 μm 60 V BCD process. From the experimental results, we can find that the layout manner of discrete-distributed types in the drain-side have little impacts on the anti-ESD capability, due to their secondary breakdown current (I<SUB>t2</SUB>) values are greater than 7 A. On the other hand, the lowest N+/P+ area ratio of discrete-distributed type has a better electrical property and anti-latchup (LU) immunity than that of the reference DUT (type-6). In other words, the layout type of "NPN_discrete 3_2co" has a higher Vt1, Vh, and VBK values; the Vt1 improvement is more than 18.2%, Vh improvement is more than 25.6%, and VBK improvement is more than 24.24% as compared with the reference DUT (type-6), respectively. Finally, it can be summarized that the "PNP" stripe-type (type 7) is the best choice for the anti- ESD/LU immunities and electrical performance considerations.
