An oxide layer spacer is formed on the sidewall of the oxide layer pattern wherein the nitride layer exposed by the oxide layer spacer is etched to expose the substrate. Impurity-containing silicon is grown on the exposed substrate to form the first silicon layer(200) wherein the first silicon layer is grown to be higher than the oxide layer pattern so that the channel region is formed. The second silicon layer of a mushroom type is formed on the first silicon layer. Ions are implanted into the second silicon layer to form the drain region(310). A nitride layer spacer(320) is formed on the sidewall of the drain region. The oxide layer pattern and the oxide layer spacer are removed. A gate insulation layer(400) is formed to cover the exposed region on the side surface of the first silicon layer and under the drain region. A predetermined thickness of a polysilicon layer is formed and planarized to expose the drain region.

Title: Method and apparatus for bandwidth allocation
IPC: H04W74/06
Filed: 2000-05-19
Abstract: A method and apparatus for requesting and allocating bandwidth in a broadband wireless communication system. The method and apparatus includes a combination of techniques that allow a plurality of CPEs to communicate their bandwidth request messages to respective base stations. One technique includes a “polling” method whereby a base station polls CPEs individually or in groups and allocates bandwidth specifically for the purpose of allowing the CPEs to respond with bandwidth requests. The polling of the CPEs by the base station may be in response to a CPE setting a “poll-me bit” or, alternatively, it may be periodic. Another technique comprises “piggybacking” bandwidth requests on bandwidth already allocated to a CPE. Currently active CPEs request bandwidth using unused portions of uplink bandwidth that is already allocated to the CPE. The CPE is responsible for distributing the allocated uplink bandwidth in a manner that accommodates the services provided by the CPE.
