Patent number: 6285073Abstract: The horizontal surface area required to contact semiconductor devices, in integrated circuits fabricated with trench isolation, is minimized without degrading contact resistance by utilizing the vertical surface area of the trench sidewall. A trench isolation region (40) is formed within the semiconductor substrate (12). A doped region (74, 96) is then formed such that it abuts the trench sidewall (24). A portion (56, 110) of the trench sidewall (24), abutting the doped region (74, 96), is then exposed by forming a recess (55, 112) within the trench isolation region (40). A conductive member (66, 114, 118) is then formed such that it is electrically coupled to the doped region (74, 96) along the exposed trench sidewall, as well as along the major surface (13) of the semiconductor substrate (12), and results in the formation of a low resistance contact structure.Type: GrantFiled: May 30, 1995Date of Patent: September 4, 2001Inventors: Kent J.

Patent number: 5616941Abstract: A floating gate (51)is formed to have a cavity (52) that increases the capacitive coupling between the floating gate (51) and a control gate for the memory cell. The memory cell may be used in EPROM, EEPROM, and flash EEPROM arrays and may be programmed and erased by hot carrier injection, Fowler-Nordheim tunneling or the like. The process sequence for forming the cavity (52) of the floating gate (51) has good process margin allowing some lithographic misalignment. In one embodiment, a multi-tiered floating gate may be formed. The multi-tier structure allows the capacitive coupling to further increase without occupying more area.Type: GrantFiled: September 20, 1995Date of Patent: April 1, 1997Assignee: Motorola Inc.Inventors: Scott S.

Patent number: 5583360Abstract: A method for forming a vertical neuron MOSFET begins by providing a substrate (12). One or more conductive layers (24 and 28) are formed overlying the substrate (12). An opening (32) is formed through a portion of the conductive layers (24 and 28) to form one or more control electrodes from the conductive layers (24 and 28). A floating gate (36, and 38) is formed adjacent each of the control electrodes. A dielectric layer (34) is formed within the opening (32) and between the control electrodes and the floating gate (36, and 38) to provide for capacitive coupling between the control electrodes and the floating gate (36, and 38). The capacitive coupling may be altered for each control electrode via isotropic sidewall etching and other methods. By forming the neuron MOSFET in a vertical manner, a surface area of the neuron MOSFET is reduced when compared to known neuron MOSFET structures.Type: GrantFiled: August 28, 1995Date of Patent: December 10, 1996Assignee: Motorola Inc.Inventors: Scott S.

Patent number: 5538922Abstract: A contact is formed in a semiconductor device (10), independent of underlying topography or pitch. In one method of the present invention, an insulating layer (18) is deposited over a semiconductor substrate (12). An etch stop layer (20) is deposited over the insulating layer. A frame structure (22) is formed on the etch stop material and defines at least one contact region (23 and/or 25) within which the etch stop material is exposed. The exposed portions of the etch stop material are removed from the contact region to expose a portion of the insulating layer. The exposed portion of the insulating layer is then anisotropically etched and at least one contact (30 and/or 32) is formed in the contact region. Depending on where the contact region is positioned, either a self-aligned contact or a non-self-aligned contact may be formed, or both types of contacts may be formed simultaneously.Type: GrantFiled: January 25, 1995Date of Patent: July 23, 1996Assignee: Motorola, Inc.Inventors: Kent J.

Patent number: 5455194Abstract: A method for the fabrication of a trench isolation region (44) includes the deposition of first, second, and third oxidizable layers (28, 34, 42). The first oxidizable layer (28) is deposited to overlie the surface of a trench (12) formed in a semiconductor substrate (10). The first oxidizable layer (28) also fills a recess (26) formed in a masking layer (14), and resides adjacent to the upper surface of the trench (12). After oxidizing the first oxidizable layer (28), a second oxidizable layer (34) is deposited to fill the trench (12). A third oxidizable layer (42) is deposited to overlie the second oxidizable layer (34) and fills a remaining portion of the recess (26). An oxidation process is performed to oxidize oxidizable layer (42) and a portion of second oxidizable layer (34) to form a trench isolation region (44). In an alternative embodiment of the invention, a shallow isolation region (46) is formed in proximity to the trench isolation region ( 44).Type: GrantFiled: March 6, 1995Date of Patent: October 3, 1995Assignee: Motorola Inc.Inventors: Barbara Vasquez, Michael P.

Patent number: 5445107Abstract: A silicon-on insulator film (38) is formed by solid phase epitaxial re-growth. A layer of amorphous silicon (36) is formed such that it is only in direct contact with an underlying portion of a silicon substrate (12). The layer of amorphous silicon (36) is subsequently annealed to form a monocrystalline layer of epitaxial silicon (38). Because the amorphous silicon layer (36) is in contact with only the silicon substrate (12), during the re-growth process, the resulting epitaxial layer (38) is formed with a reduced number of crystal defects. The resulting epitaxial silicon layer (38) may then be used to form semiconductor devices.Type: GrantFiled: November 22, 1993Date of Patent: August 29, 1995Assignee: Motorola, Inc.Inventors: Scott S. Roth, Howard C. Kirsch

Patent number: 5374573Abstract: A thin film transistor with self-aligned source and drain regions is fabricated, in one embodiment, by forming an opening (124) in a dielectric layer (118) which overlies a substrate (116). A semiconductive sidewall spacer (130) is formed around the perimeter (126) of the opening (124) and adjacent to the sidewall (128) of the opening (124). A first electrode region (120) is electrically coupled to a first portion of the semiconductive sidewall spacer (130) at a first location along the perimeter (126) of the opening (124) which lies only in the second lateral half of the opening (124). A second electrode region (122) is electrically coupled to a second portion of the semiconductive sidewall spacer (130) at a second location along the perimeter (126) of the opening (124) which lies only in the first lateral half of the opening (124). A dielectric layer (132) is formed adjacent to the semiconductive sidewall spacer (130).

Patent number: RE35294Abstract: A reduction in defects and lateral encroachment is obtained by .[.utilizing a high pressure oxidation in conjunction with.]. an oxidizable layer conformally deposited over an oxidation mask. .[.The.]. .Iadd.In one embodiment, the .Iaddend.use of high pressure oxidation provides for the formation of LOCOS oxide without the formation of defects. Any native oxide present on the substrate surface is removed by using a ramped temperature deposition process to form oxidizable layer and/or a high temperature anneal is performed to remove the native oxide at the substrate surface. In this embodiment, any oxide which can act as a pipe for oxygen diffusion is removed. Therefore, nominal or no lateral encroachment is exhibited..Iadd.Alternately, lateral encroachment can be controlled by intentionally growing an oxide layer on the substrate surface. .Iaddend.Type: GrantFiled: May 17, 1994Date of Patent: July 9, 1996Assignee: Motorola, Inc.Inventors: Barbara Vasquez, Michael P.
