Abstract:
The proposed phase-change memory cell comprises a substrate (2) housing a selection transistor, an electrical insulation layer (10) having a conductive through via (11a) electrically coupled to a first electrode (4) of the transistor, a heater element (34) including a first portion in electrical contact with the conductive through via and a second portion that extends orthogonal to the first portion, a first protection element (32) extending on the first and second portions of the heater element, a second protection element (40) extending in direct lateral contact with the first portion of the heater element and with the first protection element, and a phase-change region (50) extending over the heater element in electrical and thermal contact therewith.
Abstract:
An apparatus for nucleic acid sequencing includes: a base-detection device (4) in a detection site, the base-detection device (4) being configured to detect bases of a portion of a nucleic acid strand (F) at the detection site; and a conveying device (5), configured to extend the nucleic acid strand (F) and to cause the extended nucleic acid strand (F) to slide through the detection site along a path (A). The base-detection device (4) includes a plurality of field-effect nanowire detectors (21), arranged along the path (A) and each including a respective nanowire (25) and nucleic acid probes (27), which are defined by respective base sequences and are fixed to the respective nanowire (25).
