Hamamatsu Photonics K.K.
They seem to produce wafers/die...

On 19990813 Harris sold it's Semiconductor Corporation under the name Intersil to Citicorp Venture Capital.
Not all of Harris' semiconductors went with Intersil. I've just gotten an e-mail back from Intersil that states that Harris' CMOS logic families of parts were sold to Texas Instruments.

(also know as Hi/fn)
This is the former Stac Electronics. Stac specialized in making compression chips (using their own LZS compression algorithm) for use in things like tape drives. In the late 1990s their chip division (as well as the LZS patents) were spun off into Hi/fn, which started diversifying into encryption processing (with compression included, intended for VPN appliances and such) in 1997-1998.
The parent company dropped the Stac name, changing their name to Previo, and got into the backup, disaster recovery and helpdesk support software business (their page is at

HighPoint Technologies
IDE/ATA RAID controller chip.

HPT370A PCI Dual Channel Ultra DMA/ATA100 RAID Controller, which is the new version of HPT370 RAID controller family that integrates the latest ATA100 technology. Compared to HPT370, HPT370A adopts higher process.
Used by Adaptec and Sun Cobalt.

Holt Integrated Circuits was one of the early suppliers of low power, mixed signal cell based custom and semi-custom CMOS IC's worldwide. Applications included heart pacemakers, data and voice communications, industrial instrumentation, avionics and consumer products.
Holt has gradually changed it's focus to become a major supplier of standard products for the display driver and avionics markets.
The HI-8010 series of Dichroic LCD Display Drivers was Holt's first standard product entry into the avionics market in 1984. Along with the newer HI-8020, HI-8040 & HI-8045 drivers, they are now widely used in a variety of military and commercial avionics displays as well as ground based applications.
The initial Holt ARINC 429 standard products were introduced in 1990 in response to requests from several avionics manufacturers for an alternate, cost effective source of monolithic devices for this protocol. The product line has been further expanded with additional devices including two DESC SMD part numbers. New products are under development for both this and other avionics protocols.
With a product development strategy focused on technology trends that will provide physically smaller ICs with enhanced performance and functions, look for new innovations with astonishing levels of integration in our new product introductions over the coming years. Our expertise in providing the right components and circuits on-chip has enabled Holt to be a leader in mixed voltage and mixed mode designs for our target markets. This translates to performance, cost, and size advantages for our customers.

Hynix Semiconductor has grown steadily into a world-class Semiconductor manufacturer. Our success has been based on a number of factors such as efficiency of production, ongoing R & D investment, a clear and dedicated management team whose primary concern is customer satisfaction and a now with a exclusive focus on semiconductors.
In 1999 we merged with LG Semiconductor, with the result that Hynix Semiconductor is now the world's largest DRAM producer, as well as being the leader in semiconductor R & D by fully exploiting the synergies resulting from the integration of both companies.
