Abstract:
A method of forming a semiconductor structure, comprising:forming a nitride layer on a stack; and etching the nitride layer to form spacers in contact with sides of the stack; wherein the stack is on a semiconductor substrate, the stack comprises (i) a gate layer, comprising silicon, (ii) a metallic layer, on the gate layer, and (iii) an etch-stop layer comprising nitride, on the metallic layer; and wherein the forming is by CVD with a gas comprising SixL2x, L is an amino group, X is 1 or 2, the gate layer comprises a P+ region and an N+ region, and the P+ and N+ regions are separated by a region which is on an isolation region of the substrate having a width of at most 0.4 microns.
