Dear Members, we have fabricated Polysilicon Piezoresistors on Si(100) surface.The polysilicon was doped with spin on dopant(phosphourous dopant) and drive in and oxidation was done at same time at 1050C. The poly resistors are barely 5 microns distance apart.when i measured the resistance value the value of the resistance differed alot more than 300% change among the adjacent resistors.. Can any one suggest me why this happened? Thanks kris --------------------------------- Do you Yahoo!? Yahoo! Web Hosting - establish your business online
