A molecular synthesis array

Abstract

According to an aspect of the present inventive concept there is provided a molecular synthesis array comprising: a substrate; an insulating layer (202) arranged on the substrate; a plurality of column lines (102) extending in parallel along a column direction of the molecular synthesis array (100), and a plurality of row lines (104) extending in parallel along a row direction of the molecular synthesis array (100), wherein the column lines (102) are vertically separated from the row lines (104) and extend transverse to the row lines (104); a plurality of synthesis cells (105), wherein each cell (200) is coupled to a respective pair of a column line and a row line and comprises: a lower electrode (226) and an upper electrode (206) vertically separated from each other and embedded in the insulating layer (202), a synthesis well (223) extending from an upper surface (225) of the insulating layer (202) to the lower electrode (226), through the insulating layer (202) and through the upper electrode (206), wherein the well (223) exposes a surface portion (214) of the upper electrode (206) and a surface portion (220) of the lower electrode (226), and a select transistor (106) having a first terminal (114a), a second terminal (114b) and a gate terminal (114c), the first and second terminals (114a, 114b) forming respective source/drain terminals of the select transistor (106), wherein the gate terminal (114c) is coupled to the row line, the first terminal (114a) is coupled to the column line, the second terminal (114b) is coupled to the lower electrode (226), and the upper electrode (206) is coupled to a reference voltage, or wherein the gate terminal (114c) is coupled to the row line, the first terminal (114a) is coupled to the column line, the second terminal (114b) is coupled to the upper electrode (206), and the lower electrode (226) is coupled to a reference voltage.
