Title: Semiconductor memory device
Inventor: SUGIURA SOICHI
IPC: H01L27/108
Filed: 1989-11-28
Abstract: PURPOSE:To make an element isolation region small and fine and to obtain a fine semiconductor memory device by a method wherein, in a memory cell, arsenic whose spread of thermal diffusion is smaller than that of phosphorus is implanted as impurities used to form a source region and a drain region of a transistor for selection use. CONSTITUTION:As ions are implanted into N-type regions 6, 7, 8 which constitute a dynamic RAM cell; a source and a drain are formed respectively to form a transistor for selection use. Since a diffusion coefficient of As is smaller than that of P, As can be implanted to be shallow as shown by a solid line regarding a relationship between an atomic concentration and a depth; As is not implanted to be so wide as P as shown by a broken line. Consequently, it is possible to reduce spread of impurities by a heat treatment after that; a sufficient dielectric breakdown strength can be obtained among the regions 6, 7, 8; an element isolation region can be reduced. Thereby, the transistor can be operated for a long time.

IPC: H01L29/812
Filed: 1989-11-27
Abstract: PURPOSE:To obtain low noise characteristics over a wide current region by controlling the composition ratio of In, Ga and As and gradually reducing the composition of In in an InGaAs layer toward the electron supply layer side from the undoped layer side. CONSTITUTION:The composition ratio of In, Ga and As constituting an InGaAs layer 33 is controlled, and the composition of In in the InGaAs layer 33 is reduced gradually toward the electron supply layer 34 side from the undoped layer 32 side, thus forming the InGaAs layer 33. Consequently, the lattice constant of the InGaAs layer 33 and the bonding length of a constituent atom are augmented toward the electron supply layer 34 side from the undoping layer 32 side. As a result, the bottom of the energy level of the conduction band of a compound semiconductor element is flattened, and channel width is kept constant at all time without depending upon the concentration change of carriers. Accordingly, the carrier concentration dependency of the noise characteristics of the compound semiconductor element is inhibited, thus acquiring low noise characteristics over a wide carrier concentration region.
