    摘要: A method for forming a thin film lithium ion battery includes, under a same vacuum seal, forming a stack of layers on a substrate including an anode layer, an electrolyte, a cathode layer and a first cap over the stack of layers to protect the layers from air. Under a same vacuum seal, the stack of layers is etched with a non-reactive etch process in accordance with a hardmask, and a second cap layer is formed over the stack of layers without breaking the vacuum seal. Contacts coupled to the cathode and the anode are formed.

    摘要: After forming a first sacrificial gate stack over a portion of a first semiconductor fin located in a logic device region of a substrate, and a second sacrificial gate stack over a portion of a second semiconductor fin located in a memory device region of the substrate, in which each of the first sacrificial gate stack and the second sacrificial gate stack includes, from bottom to top, a tunneling oxide portion, a floating gate electrode, a control oxide portion, a gate conductor and a gate cap, an entirety of the first sacrificial gate stack is removed to provide a first gate cavity, and only the gate cap and the gate conductor are removed from the second sacrificial gate stack to provide a second gate cavity. Next, a high-k gate dielectric and a gate electrode are formed within each of the first gate cavity and the second gate cavity.
