History
TRW originated in 1901 with the Cleveland Cap Screw Company, founded by David Kurtz and four other Cleveland residents. Their initial products were bolts with heads electrically welded to the shafts. In 1904, a welder named Charles E. Thompson adapted their process to making automobile engine valves and by 1915, the company was the largest valve producer in the United States

At the early stage of American research, TRW was one of the companies involved in the development of automatic guns of the Bushmaster program, where, under the leadership of engineer Eugene Stoner, the author of the famous M16 rifle, a 25 mm automatic cannon was developed under the internal designation TRW model 6425, an ordinary system with automatic gas venting and locking the barrel with a rotary bolt is enough.

Semiconductors and computers
The Ramo-Wooldridge Corp formed Pacific Semiconductors in June 1954, under the leadership of Harper North who had been head of electronics R+D at Hughes Aircraft Company. The funding for this endeavor from Thompson Products was about ten times their initial investment in Ramo-Wooldridge.[ The original goal was to produce the recently invented transistor for commercial sales.
In 1957, Howard Sachar and Sanford "Sandy" Barnes invented the Varicap electronic component (also known as the varactor diode) at Pacific Semiconductors. This device reduced the physical size of radio tuners and eliminated the need for moving mechanical parts. This simplified the implementation of remote control TV tuners. Sachar and Barnes were awarded an Emmy in 2007.

Superfund site
In the 1960s and 1970s, TRW stored trichloroethylene (TCE), a critical chemical for cooling and degreasing computer chips, in tanks deep underground in Sunnyvale, California for later use. TCE is also found in household cleaners. As a result of pipe and tank degradation, the tanks leaked into the ground, resulting in contaminated soil and groundwater. TCE was later determined to be toxic to humans at high concentrations. In 2013, ''The Atlantic

light and oxygenation and excavate the contaminated soil. In 1994, a public health study determined that the groundwater was still unacceptably contaminated, which can cause vapor intrusion. The EPA says the site has institutional controls to protect people from contact with affected water. Drinking water in the area comes from Hetch Hetchy and municipal wells.

using bacteria in molasses to naturally breakdown the TCE into harmless sub-compounds was implemented. Other measures included engineering vapor pathways to avoid direct human contact by releasing it into the air. Jared Blumenfeld, the former EPA director, said that TCE released in the air after the cleanup efforts reduces the concentrations to levels that eliminate health risks. Blumenfeld said that airborne TCE is not ideal, but the cleanup has reduced the toxins by 90% , according to Max Shahbacian, the project's lead at California State Water Resources Control Board before it was transferred to the EPA, and geologist Michael Calhoun.
In 2014 and 2015, a newly required vapor intrusion test of the surrounding residential area, including homes, apartment buildings, and four schools, showed unacceptable levels of TCE. A 2011 study had revealed TCE caused birth defects and cancer

expressed concerns that the EPA had not been properly monitoring the site and notififying residents of a possible health issue. The EPA litigated with the responsible parties in order update its notification and testing measures to warn residents about possible exposure as early as possible and keeping people away from any unsafe areas.
, the site is owned by GI Partners, an investment company, and has been leased by Apple Inc. since 2015 for research and development . The octagonal glass building was renovated in 2014 and made available for occupancy in 2015. The safety of the site was verified by the EPA. In 2016, the Donald Trump administration cut funding the Superfund program by $330 million and EPA funding by more than 30%, resulting in a significant reduction in enforcement and testing. During his presidency, the EPA increased its use of consent decrees, or administrative settlements, to ensure progress continued under the budget cuts, forcing responsible parties to pay for the cleanup. Scott Pruitt, Trump's head of the EPA threatened to cut budgets again for the enforcement. In 2019, the EPA and Philips Semiconductors agreed to a consent decree, with Northrop Grumman as a signatory, to fund the remaining cleanup and monitoring of the site, along with two nearby sites collectively known as the "Triple Site".
In March 2021, Ashley Gjøvik, a former Apple program manager, publicized concerns that the site had not been properly tested since 2015 after receiving an email from Apple notifying employees of forthcoming vapor intrusion testing. An EPA study in 2019 had confirmed the previous remedies effective, but Gjøvik told ''TechCrunch

Based on field testing done between April 24, 2023 and May 5, 2023, the EPA concluded that vapor intrusion was being prevented.
