Glossary

A~E

 Adjusted net D/E ratio

The net D/E ratio is one of the safety indicators calculated from net interest-bearing debt, obtained by subtracting cash and cash equivalents from the interest-bearing debt, divided by shareholders’ capital.
This is an index adjusted in consideration of hybrid finance equity. We adopt it as a Key Performance Indicator (KPI) for financial soundness.

Bulk

This is a form of industrial gas supply. Cryogenic liquefied gas produced at an industrial gas production base is supplied to a storage tank on the users’ premises via a tanker truck. It is common to have a relatively medium-term supply contract with users.

Cubic meter

This is an internal term. It is common to use the Japanese character (米) to indicate meters, but we call cubic meters ryube.

Discrete

A semiconductor device with a single function to control the flow of electricity, such as a transistor or diode. A circuit that integrates these functions becomes an integrated circuit (IC), and a system LSI (Large Scale Integrated Circuit) is a further integration of ICs

DRAM [Dynamic Random Access Memory]

Memory that can only record data when electricity is present, and is used as the main memory for operating systems and applications in PCs and smartphones.

Diborane(B₂H₆)

A type of electronic material gas.

Semiconductor structures are formed by the deposition (layering) of molecules such as silicon, which is the main material of semiconductors, using chemical vapor deposition (CVD) and other methods.
By adding Boron (chemical formula: B), which is contained in Diborane (chemical formula: B₂H₆) gas, to these stacked films, the electrical characteristics and properties of the target film are changed, and the film is used to add or improve semiconductor functions.
Targeted Devices > Logic IC, DRAM, Flash Memory, Discrete etc.

It is also used in the metal wiring deposition process to perform the necessary pretreatment in the deposition area in order to achieve uniform, stable, and high-speed film growth.
Targeted Devices > Flash Memory, DRAM etc.

F~J

Hybrid finance

This is a financing method, and we put it into practice with a combination of hybrid bonds (corporate bonds) and hybrid loans (borrowing) for the first time in 2019. Generally speaking, the portion accepted as equity by an external rating agency can be treated as “capital” when analyzing a company using a safety index.

Industrial gas

Before the early 2000s, oxygen and nitrogen used for medical purposes were separated. Now however, gases for both industrial and medical purposes are collectively called industrial gases. In English, industrial gas is the common term.

Flash Memory

Memory that retains its memory even when the power is turned off. It is widely used as a storage medium (storage/SSD, etc.) for memory cards, PCs, smartphones, servers, etc. The demand for 3D NAND, which has a stacked memory structure, is growing rapidly, and the demand for various gases used for film deposition is also increasing due to the stacking process.

K~O

On-site

This is a form in which industrial gases are supplied. An air separation unit is installed on the user’s premises or adjacent thereto to supply gas directly through piping. The common practice is to conclude a long-term supply contract with users for underground piping.

Logic IC [Integrated Circuit]

Information processing and processing used in a wide range of applications, such as the central processing unit (CPU), the core component of personal computers, and in the control of smartphones and home appliances. Highly functional semiconductor devices that are required to be faster, smaller, and more power-efficient. Memory devices that are classified into several categories according to their functions. DRAM, flash memory, etc. are well known.

Memory IC

Memory devices that are classified into several categories according to their functions. DRAM, flash memory, etc. are well known.

P~T

Package

This is one of the industrial gas supply forms to transport the gas produced at the industrial gas plants to the filling station, filling in small portions into cylinders (also called bombe) and supply by vehicles such as trucks to end users. It is common to have a relatively short-term supply contract with users.
