  • Patent number: 11245024
    Abstract: A method of manufacturing a semiconductor device includes forming a fin structure comprising alternately stacked first semiconductor layers and second semiconductor layers over a substrate. A sacrificial gate structure is formed over the fin structure. Spacers are formed on either side of the sacrificial gate structure. The sacrificial gate structure is removed to form a trench between the spacers. The first semiconductor layers are removed from the trench, while leaving the second semiconductor layers suspended in the trench. A self-assembling monolayer is formed on sidewalls of the spacers in the trench. Interfacial layers are formed encircling the suspended second semiconductor layers, respectively. A high-k dielectric layer is deposited at a faster deposition rate on the interfacial layers than on the self-assembling monolayer. A metal gate structure is formed over the high-k dielectric layer.

  • Publication number: 20210335440
    Abstract: A memory test system including a memory storing non-transitory machine executable instructions configured to generate test patterns. A processor or state machine is configured to execute the machine executable instructions to generate the test patterns. A memory controller receives the test patterns, writes the generated test patterns to a memory being tested, and reads the test patterns from the memory being tested to create read test patterns. A comparator or controller is configured to compare the generated test patterns to the read test patterns and responsive to differences between the generated test patterns and the read test patterns, generate a memory read error. Pass/fail registers may store data and a memory address associated with the memory read error. The test patterns can be stored for a period of time before being read to test the ability of the memory being tested to store the test pattern.
