Dear vbhupendra,
Following is some part of the input-layer in LVS command file, it is a bipolar process, layer 101 is defined in my techfile as a text layer.
NP = 1
ISO = 6
B = 7
E = 11
C = 13
TH = 15
SM = 16
M = 14 TEXT = 101 ATTACH = M
;;;;;;;;;TEXT = 101 attach= M
SUBSTRATE = BULK 256
And I have defined a single NPN as follow assuming that there is no other device, can you check it for me, NP is the N+ burried layer
CONNECT-LAYER =CNPN BNPN ENPN M
AND C BULK CONT
select e inside b enpn
select b enc e bnpn
select np enc enpn cnpn
select e outside b acont1
and acont1 cnpn bcont2
CONNECT M BNPN BY CONT
CONNECT M ENPN BY CONT
CONNECT M CNPN BY bCONT2
ELEMENT BJT[NV] ENPN CNPN BNPN ENPN
*BREAK ALVS
LVSCHK[RPCAET] RESVAL=2 CAPVAL=2 DIOAREA=1 EAPER=1
