Title: Formation of self-aligned contact
Inventor: KIYOZUMI FUMIO
IPC: H01L21/283
Filed: 1985-07-22
Abstract: PURPOSE:To easily obtain a semiconductor element having a fine construction and to enable a highly integrated semiconductor device to be manufactured with a high yield, by using a mask resistive to oxidation which is formed by the implantation of nitride ions for selectively growing an oxide film, and by forming a contact between a metal wire and a diffused layer in self-alignment through this oxide film. CONSTITUTION:A polycrystalline silicon film 5a is etched by using resist 6 as a mask so that a gate electrode 5b is formed. Nitride ion are implanted into the surface of a semiconductor substrate by using the resist 6 on the gate electrode as a mask, and the substrate is then subjected to a heat treatment. During this heat treatment, the region 7a into which the nitride ions have been implanted is converted to a nitride layer 7b highly resistive to oxidation. The polycrystalline silicon surface of the gate electrode 5b is selectively oxidized to form a thick oxide film 8 by using the nitride layer 7b as a mask resistive oxide film 8 by using the nitride layer 7b as a mask resistive to oxidation. Consequently, the gate electrode 5b is thereby covered with the oxide film 8. Arsenic or phosphorus is diffused to form diffused layers 9 and 10 which will constituted source and drain regions. Finally, a metal film of aluminium or an aluminium alloy is adhered and patterned thereon.

Filed: 1999-06-08
Abstract: PROBLEM TO BE SOLVED: To relieve a load of a system by validating absence transfer to only a first incoming call so as to avoid wasteful transfer on the arrival of a plurality of incoming calls to the same extension. SOLUTION: The private branch exchange discriminates whether an incoming call has already been transferred, on the basis a data table MB1 of a storage device 7 at the arrival of an incoming call to an extension to which absence transfer it set, and when the incoming call is not transferred, the transfer of the incoming call is executed, while storing a fact of the transferred incoming call to the data table MB1 of the storage device 7. When the new incoming call arrives in the extension, since the transfer of the incoming call is stored in the data table MB1 of the storage device 7, the transfer of the new incoming call is restricted. When a data table MB4 of the storage device 7 stores a proxy destination extension, the new incoming call is transferred to the proxy destination extension. When the first incoming call is terminated, contents of the data table MB1 of the storage device 7a re deleted to prepare for the incoming call that is expected to be received next.
