Latest Patents
Shaikh N Mohammad's latest patents include a method of making a carrier conduction conductor-insulator semiconductor (CIS) heterojunction transistor. This innovative CIS transistor is built on a silicon (Si) substrate, where a layer of n-type Si is deposited. A trench is formed through the n-type Si layer, which may extend slightly into the substrate. This trench is filled with an insulator, preferably SiO₂. A layer of p-type Si₁-zGeₓ (where z is the mole fraction of Ge and 0.1 ≤ z ≤ 0.9) is then deposited on the n-type Si layer. A p⁺ base contact region is defined in the p-type Si₁-zGeₓ region above the oxide-filled trench. An n-type dopant is ion implanted into both the Si₁-zGeₓ and n Si layers, forming a collector region. A thin oxide layer is deposited on the Si₁-zGeₓ layer, and a low work function metal such as Al, Mg, Mn, or Ti is selectively deposited to define an emitter. Alternatively, the emitter may be p⁺ polysilicon. The thin oxide is then opened to define collector and base contacts, with a suitable metal, such as Al, deposited in the base and collector contacts.
