How to draw layout for a crossover
img Tutorial Home

A. METAL1

Crossover connects two METAL1 pieces together, jumping over another METAL1 piece between them. Assume we are going to connect two METAL1 pieces 300um away from each other.

B. PMMA Insulation Layer

Select PMMA (drw) from LSW window and draw a rectangle of 200um x 300um, completely enclosing the METAL1 piece in the middle by 50um on four edges.

C. PEDOT Conductive Layer

Select PEDOT_CRV (drw) from LSW window and draw a rectangle of 100um x 400um, placed over the METAL1 piece in the middle and extending onto the two METAL1 pieces to connect by 50um.

D. CONTACT

For LVS purpose, dummy contacts are required in layout. Select CONTACT (drw) from LSW window and draw rectangles on two sides where PEDOT overlaps METAL1.

E. Substrate

For LVS purpose, substrate is required in layout. Select SUB (drw) from LSW window and draw a rectangle to enclose everything.

 The final layout should look like this:
