    摘要: The invention includes methods of forming recessed access devices. A substrate is provided to have recessed access device trenches therein. A pair of the recessed access device trenches are adjacent one another. Electrically conductive material is formed within the recessed access device trenches, and source/drain regions are formed proximate the electrically conductive material. The electrically conductive material and source/drain regions together are incorporated into a pair of adjacent recessed access devices. After the recessed access device trenches are formed within the substrate, an isolation region trench is formed between the adjacent recessed access devices and filled with electrically insulative material to form a trenched isolation region.

    摘要: The invention includes methods of forming field effect transistor gates. In one implementation, a series of layers is formed proximate a semiconductive material channel region. The layers comprise a gate dielectric layer and a conductive metal-comprising layer having an ion implanted polysilicon layer received therebetween. Patterned masking material is formed over the series of layers. Using the patterned masking material as a mask, etching is conducted through the conductive metal-comprising layer and only partially into the ion implanted polysilicon layer. After such etching, the ion implanted polysilicon is annealed effective to electrically activate implanted impurity atoms received therein. Other aspects and implementations are contemplated.

    摘要: According to one embodiment of the invention, a high pressure anneal is utilized to form titanium silicide at the bottom of a contact hole, at a pressure of at least approximately 1.1 atmospheres, from a reaction between deposited titanium and underlying silicon. When such high pressures are used, temperatures of less than approximately 700 degrees Celsius are utilized. According to another embodiment of the invention, a conductive plug fill material is deposited within a contact hole such that the plug structure is relatively free of voids. Either during deposition of the conductive plug fill material or after such deposition, the conductive plug fill material is subjected to a high pressure force-fill, at a pressure of at least approximately 1.1 atmospheres. When such high pressures are used, temperatures of less than approximately 700 degrees Celsius are utilized for the force-fill. Aluminum can be used for the conductive plug fill material when using this embodiment of the invention. In further embodiments, dielectrics deposited between conductive layers are reflowed at high pressure and low temperature. Still further, multiple metalized layers are connected by vias filled with conductive material using high pressure and low temperature.
