Abstract:
Embodiments relate to a two-transistor (2T) floating-body cell (FBC) for embedded- DRAM applications. Further embodiments pertain to a floating-body/ gate cell (FBGC), which yields reduction in power dissipation, in addition to better signal margin, longer data retention, and higher memory density.

Abstract:
A method of forming a doped region (34, 32) includes, in one embodiment, implanting a dopant into a region (30, 28) in a semiconductor substrate (12), recrystallizing the region by performing a first millisecond anneal, wherein the first millisecond anneal has a first temperature and a first dwell time, and activating the region using as second millisecond anneal after recrystallizing the region, wherein the second millisecond anneal has a second temperature and a second dwell time. In one embodiment, the first millisecond anneal and the second millisecond anneal use a laser (52). In one embodiment, the first temperature is the same as the second temperature and the first dwell time is the same as the second dwell time. In another embodiment, the first temperature is different from the second temperature and the first dwell time is different from the second dwell time.
Abstract:
A strained semiconductor layer (18) is achieved by a method for transferring stress from a dielectric layer (30) to a semiconductor layer (18). The method comprises providing a substrate (12) having a semiconductor layer (18). A dielectric layer (30) having a stress is formed over the semiconductor layer (18). A radiation anneal (32) is applied over the dielectric layer of a duration not exceeding 10 milliseconds to cause the stress of the dielectric layer (30) to create a stress in the semiconductor layer (18). The dielectric layer (30) may then be removed. At least a portion of the stress in the semiconductor layer (18) remains in the semiconductor layer after the dielectric layer (30) is removed. The radiation anneal can be either by using either a laser beam or a flash tool. The radiation anneal can also be used to activate source/drain regions (26, 28).
