    Abstract: At least one method, apparatus and system disclosed herein involves forming trench in a gate region, wherein the trench having an oxide layer to a height to reduce or prevent process residue. A plurality of fins are formed on a semiconductor substrate. Over a first portion of the fins, an epitaxial (EPI) feature at a top portion of each fin of the first portion. Over a second portion of the fins, a gate region is formed. In a portion of the gate region, a trench is formed. A first oxide layer at a bottom region of the trench is formed. Prior to performing an amorphous-silicon (a-Si) deposition, a flowable oxide material is deposited into the trench for forming a second oxide layer. The second oxide layer comprises the flowable oxide and the first oxide layer. The second oxide layer has a first height.

  • Publication number: 20180012798
    Abstract: A method provides a structure having a FinFET in an Rx region, the FinFET including a channel, source/drain (S/D) regions and a gate, the gate including gate metal. A cap is formed over the gate having a high-k dielectric liner and a core. Trench silicide (TS) is disposed on sides of the gate. The TS is recessed to a level above a level of the gate and below a level of the cap. An oxide layer is disposed over the structure. A CB trench is patterned into the oxide layer within the Rx region to expose the core and liner at an intermediate portion of the CB trench. The core is selectively etched relative to the liner to extend the CB trench to a bottom at the gate metal. The CB trench is metalized to form a CB contact.

  • Patent number: 9208094
    Abstract: Systems and methods are provided for managing storage cache resources among all servers within the cluster storage environment. A method includes partitioning a main cache of a corresponding node into a global cache and a local cache, sharing each global cache of each node with other ones of the nodes of the multiple nodes, and dynamically adjusting a ratio of an amount of space of the main cache making up the global cache and an amount of space of the main cache making up the local cache, based on access latency and cache hit over a predetermined period of time of each of the global cache and the local cache.

  • Patent number: 9190303
    Abstract: A bonding layer of a first wafer article is thermally treated and a bonding layer of a second wafer article is thermally treated in accordance with first and second process parameters, respectively prior to bonding the first wafer article with the second wafer article. First and second grid distortion in the first and second wafer articles is measured and a difference is determined between the first and second grid distortions. A prediction is made for maintaining the difference within a prescribed tolerance. At least one of the first process parameters and the second process parameters is conditionally varied in accordance with the prediction. The thermal treating of the first and second wafer articles can then be performed with respect to another pair of the first and second wafer articles prior to bonding to one another through their respective bonding layers.
