Abstract: A device for synthesis of macromolecules is disclosed. In one aspect, the device comprises an ion-releaser having a synthesis surface comprising an array of synthesis locations arranged for synthesis of the macromolecules. The ion-releaser also includes an ion-source electrode, which is arranged to contain releasable ions and is arranged to be in contact with each of the synthesis locations of the synthesis surface, thereby release ions to the synthesis locations. The ion-releaser further comprises activating electrodes, which are arranged to be in contact with the ion-source electrode, wherein each one of the activating electrodes is arranged in association with one of the synthesis locations via the ion-source electrode. The ion-releaser is arranged to release at least a portion of the releasable ions from the ion-source electrode to one of the synthesis locations, by activation of the activating electrode associated with the synthesis location.

Abstract: In one aspect, a method for manufacturing a three-dimensional (3D) semiconductor device is disclosed. It includes providing a vertical stack of alternating layers of a first layer type and a second layer type, and providing a first trench and a second trench adjacent the vertical stack. The first trench and the second trench can define a fin. The method further can include recessing the first layer type to form recesses extending into the fin, providing a first electrode in individual ones of the recesses, and providing a second electrode in the first trench and the second trench. The method further can include providing, for individual ones of the recesses, a lateral stack including a memory element, a middle electrode, and a selector element. The lateral stack can extend between the first electrode and the second electrode, thereby forming a memory device.

Abstract: A three dimensional shallow trench isolation structure including sets of parallel trenches extending in two perpendicular directions may be formed by depositing a conformal deposition in a first set of parallel trenches, oxidizing the second set of trenches to enable selective deposition in said second set of trenches and then conformally depositing in said second set of trenches. In some embodiments, only one wet anneal, one etch back, and one high density plasma chemical vapor deposition step may be used to fill both sets of trenches.

Abstract: A substrate may have active areas at different levels separated by a mask. Along the mask may be a shallow trench isolation. Along the shallow trench isolation may be a LOCOS isolation. The shape of a substrate transition region between the levels may be tunably controlled. The shallow trench isolation may reduce the bird's beak effect.
