Abstract:
1. An impedance tunable semiconductor component, comprising a first conductive region and a second region, said first conductive region comprising a first type dopant composition, said second region comprising a second type dopant composition, said first conductive region and said second region being contiguous, said first conductive region defining a conductive path, said second type dopant composition non-conductive relative to said first type dopant composition, said first conductive region comprising a first link member and a second link member, said first link member and said second link member separated by a gap region defined by said second region, said first conductive region having a heat modifiable dopant profile, said second region having a heat modifiable dopant profile at least with respect to said gap region, and a current mask region disposed in said gap region spaced apart from said first link member and said second link member said current mask region having a heat modifiable dopant profile, and wherein said current mask region comprises a third type dopant composition sufficiently different from said first type dopant composition and said second type dopant composition to offset leakage of electrical current across the gap region between the first link member and the second link member.
