Abstract: Systems and methods are provided for improved point querying of a database. The index values are separated from data and retained in cache memory to allow access without requiring a disk input/output (I/O) operation and thereby having less latency resulting from such disk I/O operations. The index values can be compressed using an algorithm such as Crit-Bit-Trie to allow storage of the index values in limited cache memory space. The index values can be selected for storage according to a least recently used approach when cache memory is insufficient to store all index values to maintain a hit rate for the cached portion and reduce the disk I/O operations.

Abstract: A sidewall protection layer is formed on sidewall spacers of a dummy gate structure of a semiconductor device prior to etching an underlying fin structure to form a source/drain recess. The sidewall protection layer enables the profile of the source/drain recess to be precisely controlled so that etching into residual dummy gate material near the source/drain recess is minimized or prevented. The sidewall protection layer may be removed or retained in the semiconductor device after formation of the source/drain recess. The sidewall protection layer reduces the likelihood of the source/drain regions of the semiconductor device contacting the metal gate structures of the semiconductor device after the dummy gate structures are replaced with the metal gate structures. Thus, the sidewall protection layer reduces the likelihood of electrical shorting between the source/drain regions and the metal gate structures.
