{{nihongo|'''Rohm Semiconductor'''|ローム株式会社|Rōmu Kabushiki-gaisha|}} (styled as ROHM) is a Japanese electronic parts manufacturer based in [[Kyoto, Kyoto|Kyoto]], Japan. Rohm was incorporated as Toyo Electronics Industry Corporation by Kenichiro Sato (佐藤 研一郎) on September 17, 1958.

The company was originally called R.ohm,<ref>{{Cite web |title=Company {{!}} ROHM Semiconductor |url=https://www.rohm.com/company |access-date=2022-12-12 |website=www.rohm.com}}</ref> which was derived from R for resistors, the original product, plus [[ohm]], the unit of measure for [[Electrical resistance and conductance|resistance]].

The name of the company was officially changed to Rohm in 1979 and then changed again to Rohm Semiconductor in January 2009.

When Rohm was established, [[resistor]]s were its main product. Later, the company began manufacturing [[semiconductor]]s. [[integrated circuit|IC]]s and discrete semiconductors now account for about 80% of Rohm's revenue.

Through 2012, Rohm was among the top 20 semiconductor sales leaders.

==International expansion==
In 2016, Rohm started the construction of their production facility in [[Kelantan]], [[Malaysia]] and commenced the operation in April 2017. A few years later in 2022, Rohm expanded their facility by approximately 1.5 times bigger with the plan to start operating in 2023. The original plant mainly focuses on the production of discrete semiconductors such as [[diodes]] while the expanded facility will be focusing on the production of analog LSIs and [[transistors]].<ref>{{cite web |url=https://www.rohm.com/news-detail?news-title=new-production-facility-in-malaysia&defaultGroupId=false|title=ROHM Group establishes a New Production Facility in Malaysia to increase production capacity of analog LSIs and transistors|date=14 December 2021|access-date=15 March 2022|website=Rohm Semiconductor}}</ref>

== Products ==
Rohm produces a range of products such as power stage ICs aimed at power supplies, [[CMOS amplifier|CMOS operational amplifier]] used to boost sensor-signals as well as [[Hall effect sensor]]s.<ref>{{cite web|access-date=2024-08-28 |date=2023-08-31 |title=ROHM launches power-stage ICs with built-in 650V GaN HEMTs and gate driver |publisher=semiconductor-today.com |url=https://www.semiconductor-today.com/news_items/2023/aug/rohm-310823.shtml}}</ref><ref>{{cite web|access-date=2024-08-28 |date=2024-08-08 |title=Rohm Announces the 'Industry's Smallest' CMOS Op Amp |publisher=allaboutcircuits.com |url=https://www.allaboutcircuits.com/news/rohm-announces-the-industrys-smallest-cmos-op-amp/}}</ref><ref>{{cite web|access-date=2024-08-28 |date=2023-08-28 |title=Rohm's Automotive Hall ICs Offer 'Industry-Leading Withstand Voltage' |publisher=allaboutcircuits.com |url=https://www.allaboutcircuits.com/news/rohms-new-automotive-hall-ics-offer-industry-leading-withstand-voltage/}}</ref> The company also sells DC to DC controller ICs, current sensor ICs and AC to DC converters.<ref>{{cite web|access-date=2024-08-28 |date=2023-03-23 |title=ROHM's ultra-high-speed control IC technology maximizes performance of GaN switching devices |publisher=semiconductor-today.com |url=https://www.semiconductor-today.com/news_items/2023/mar/rohm-230323.shtml}}</ref><ref>{{cite web|access-date=2024-08-28 |date=2023-03-14 |title=ROHM Boasts ±1% Accuracy in New Current Sense Amplifier ICs |publisher=allaboutcircuits.com |url=https://www.allaboutcircuits.com/news/rohm-boasts-1-accuracy-in-new-current-sense-amplifier-ics/}}</ref><ref>{{cite web|access-date=2024-08-28 |date=2021-06-21 |title=ROHM launches first surface-mount AC/DC converter ICs with built-in 1700V SiC MOSFET |publisher=semiconductor-today.com |url=https://www.semiconductor-today.com/news_items/2021/jun/rohm-210621.shtml}}</ref>
