Abstract: Provided is a GaAs wafer that can suitably be used to produce LiDAR sensors in particular and a method of producing a GaAs ingot that can be used to obtain such a GaAs wafer. The GaAs wafer has a silicon concentration of 5.0×1017 cm?3 or more and less than 3.5×1018 cm?3, an indium concentration of 3.0×1017 cm?3 or more and less than 3.0×1019 cm?3, and a boron concentration of 1.0×1018 cm?3 or more. The average dislocation density of the GaAs wafer is 1500/cm2 or less.

Abstract: Provided is a GaAs ingot with which a GaAs wafer having a carrier concentration of 5.5×1017 cm?3 or less and low dislocation density with an average dislocation density of 500/cm2 or less can be obtained by adding a small amount of In with Si. A seed side end and a center portion of a straight body part of the GaAs ingot each have a silicon concentration of 2.0×1017 cm?3 or more and less than 1.5×1018 cm?3, an indium concentration of 1.0×1017cm?3 or more and less than 6.5×1018 cm?3, a carrier concentration of 5.5×1017 cm?3 or less, and an average dislocation density of 500/cm2 or less.

Abstract: A transfer method controls transfer of a template in a system (1) that supports introduction of an ERP package for a plurality of customer companies. The template includes: a plurality of software modules necessary for performing a plurality of functions including functions tailored to a plurality of industries or functions tailored to part of the industries; and a plurality of parameter settings used for determining operations of the software modules. The transfer method includes: a reception step of receiving an instruction to transfer a template; and a transfer step of transferring, on receiving the instruction to transfer a template, a plurality of software modules and a plurality of parameter settings which are included in the template from a first server (20) used for developing the template to a second server (30) used for performing a test for each customer company.
