Virtual Si Museum /2107/ TG4 and TG50

The TG1-TG5 series transistor are the first industrially mass-produced BJT transistors in Poland. The serial production was started by the TEWA Semiconductor Factory, Warsaw, in early1960s. Then, the TG50-TG55 series, was also manufactured by the TEWA in 1961–1962. 

The TG4 (see Pic: below) is low power, low frequency, pnp germanium (Ge) alloy transistor (with 75 mW max collector power) [1].

The TG50 (below) is medium power, low frequency,  pnp germanium (Ge) alloy transistor (with 175 mW max collector power) [2].

An initial stage of Polish semiconductor microelectronics research activities has been reviewed by Prof. Jerzy Pułtorak. In his paper [3], he has reviewed activities of leading Polish R&D groups starting from Department of Electronics, Polish Academy of Sciences (PAN) founded on July 4, 1952 till foundation of the Instytut Technologii Elektronowej (ITE, Warsaw) early 1960 (now Sieć Badawcza Łukasiewicz - Instytut Mikroelektroniki i Fotoniki).  The first, in Poland, experimental germanium point-contact transistor TP-1 [4] has been developed by Prof. Rosinski just after John Bardeen, Walter Brattain and William Shockley have invented a semi-conductor triode (transistor) [5] on December 23, 1947.

[mos-ak] [Final Program] 1st Asia/South Pacific MOS-AK Workshop (Online) FEB. 25-26, 2021

Together with IEEE Young Professionals (at iitk.ac.in), the MOS-AK workshop online host as well as all the Extended MOS-AK TPC Committee, we have the pleasure to invite to the very first Asia/South Pacific MOS-AK Workshop which will be Virtual/Online event. Scheduled, 1st Asia/South Pacific MOS-AK Workshop, aims to strengthen a network and discussion forum among experts in the field, enhance open platform for information exchange related to compact/SPICE modeling and Verilog-A standardization, bring people in the compact modeling field together, as well as obtain feedback from technology developers, circuit designers, and TCAD/EDA tool developers and vendors.

The MOS-AK workshop program is available online: 

http://www.mos-ak.org/asia_pacific_2021/

Venue: Virtual/Online MOS-AK Workshop - FEB. 25-26, 2021

• Day 1 (FEB.25) begins: 8:00 in Europe; 12:30 in India; 15:00 in China
• Day 2 (FEB.26) begins: 8:00 in Europe; 12:30 in India;15:00 in China

Online Free Registration is open, now:
