Patent ID: 7919402

Claim:
A method of implantation for semiconductor manufacturing, comprising the following steps: a. creating a flow of C n H m vapor or gas, where n and m are integers such that n>1 and m≧0; b. introducing said vapor or gas into the ion source of an ion implanter; c. ionizing said vapor or gas to form ions of C n H x + , where x is a positive integer or zero; d. accelerating said ions into a n- or p-type silicon substrate at a depth R p ; e. implanting a dopant ion of the form A n R z H x + to a silicon depth R′ p <R p , defining a doped silicon substrate, where A is either an n- or p-type dopant in silicon, selected from the group of As, P, B, In or Sb, and where R denotes a molecule whose atomic constituents are not injurious to the silicon transistor formation process, selected from the group of Si, Ge, F, or C, and n, x and z are positive integers greater than or equal to zero; f. activating said doped silicon substrate with a heat treatment to cure defects resulting from said implanting of said dopant ion.
