    摘要: A method of compensating resistivity of a near-surface region of a substrate includes epitaxially growing a buffer layer on the substrate, wherein the buffer is grown as having a dopant concentration as dependent on resistivity and conductivity of the substrate, so as to deplete residual or excess charge within the near-surface region of the substrate. The dopant profile of the buffer layer be smoothly graded, or may consist of sub-layers of different dopant concentration, to also provide a highly resistive upper portion of the buffer layer ideal for subsequent device growth. Also, the buffer layer may be doped with carbon, and aluminum may be used to getter the carbon during epitaxial growth.

    摘要: The invention includes methods of forming epitaxial silicon-comprising material and methods of forming vertical transistors. In one implementation, a method of forming epitaxial silicon-comprising material includes providing a substrate comprising monocrystalline material. A first portion of the monocrystalline material is outwardly exposed while a second portion of the monocrystalline material is masked. A first silicon-comprising layer is epitaxially grown from the exposed monocrystalline material of the first portion and not from the monocrystalline material of the masked second portion. After growing the first silicon-comprising layer, the second portion of the monocrystalline material is unmasked. A second silicon-comprising layer is then epitaxially grown from the first silicon-comprising layer and from the unmasked monocrystalline material of the second portion. Other aspects and implementations are contemplated.

    摘要: The present disclosure provides methods and systems for controlling temperature. The method has particular utility in connection with controlling temperature in a deposition process, e.g., in depositing a heat-reflective material via CVD. One exemplary embodiment provides a method that involves monitoring a first temperature outside the deposition chamber and a second temperature inside the deposition chamber. An internal temperature in the deposition chamber can be increased in accordance with a ramp profile by (a) comparing a control temperature to a target temperature, and (b) selectively delivering heat to the deposition chamber in response to a result of the comparison. The target temperature may be determined in accordance with the ramp profile, but the control temperature in one implementation alternates between the first temperature and the second temperature.

    摘要: An improved charge storing device and methods for providing the same, the charge storing device comprising a conductor-insulator-conductor (CIC) sandwich. The CIC sandwich comprises a first conducting layer deposited on a semiconductor integrated circuit. The CIC sandwich further comprises a first insulating layer deposited over the first conducting layer in a flush manner. The first insulating layer comprises a structure having a plurality of oxygen cites and a plurality of oxygen atoms that partially fill the oxygen cites, wherein the unfilled oxygen cites define a concentration of oxygen vacancies. The CIC sandwich further comprises a second conducting layer deposited over the first insulating layer in a strongly oxidizing ambient so as to reduce the concentration of oxygen vacancies in the first insulating layer, so as to provide an oxygen-rich interface layer between the first insulating layer and the second conducting layer, and so as to trap a plurality of oxygen atoms within the second conducting layer. The oxygen-rich interface layer and second conducting layer act as oxygen vacancy sinks for absorbing migrating oxygen vacancies that originate from the first insulating layer to thereby reduce the concentration of oxygen vacancies in the first insulating layer and to thereby reduce the buildup of oxygen vacancies at the interface layer. Thus, the first insulating layer provides an increased dielectric constant and an increased resistance to current flowing therethrough so as to increase the capacitance of the CIC sandwich and so as to reduce leakage currents flowing through the CIC sandwich.
